If you’re looking for a device to provide skin rejuvenating benefits or to treat chronic skin disorders like eczema or psoriasis, you may find red light to be enough.

Red wavelengths benefit the skin and systems within the skin tissue, including the circulatory system, peripheral nervous system, and hair follicles.

When infrared waves come in contact with your body’s tissues, it causes the molecules to vibrate, which produces heat and causes a rise in body temperature.

A large body of scientific research suggests wavelengths in the red/NIR electromagnetic scale can safely deliver a variety of health benefits, without adverse effects.

What's more is that the BIOMAX Series now features a blue light therapy. All models ship with a 480nm light that treats the skin. This has even more synergistic benefits when used at the same time as the other wavelengths.

“Being able to complete the whole picture of diode to on-chip laser to systems applications is really just an optimization challenge, and of course one we’re really excited to work on,” says Yang. “But even with the low optimization we start with, it’s still able to achieve lasing.”

Beyond 850nm, infrared waves penetrate even deeper. Infrared light therapy is most commonly used in infrared saunas, which typically use wavelengths in the 1000nm range.

These feature a blend of five of the most beneficial red/NIR wavelengths, delivered in a specific ratio designed for the most comprehensive skin-to-deep-tissue treatment. These also include the new 480nm blue lights that have further treatment benefits.

Here’s what you need to know about these wavelengths: what they are, their benefits, when to use each one, and how they can work together to improve your health and wellbeing.

Technically, both NIR and IR light therapy fall into the same category of invisible infrared wavelengths in the electromagnetic spectrum.

NIR light is closely related to red light in that it doesn’t cause heating of the body, which occurs in wavelengths in the mid to far-infrared light spectrum.

Unlike numerous other types of lasers such as semiconductor lasers, titanium:sapphire lasers have proved extremely difficult to miniaturize because traditional designs require very high input power to achieve lasing. “Titanium:sapphire has the ability to output very high powers, but because of the way the laser level structure works – specifically the fluorescence has a very short lifetime – you have to pump very hard in order to see appreciable amounts of gain,” says Stanford’s Joshua Yang. Traditional titanium:sapphire lasers have to be pumped with high-powered lasers – and therefore cost in excess of $100,000.

Among the many potential benefits of light therapy using red/NIR wavelengths, these four benefits stand out as the keys to supporting the body’s self-healing mechanisms.

Nonetheless, we recommend a combination of red and NIR light. This has been clinically proven to stimulate positive biological processes in the body, including:

If titanium:sapphire lasers could be miniaturized and integrated into chips, potential applications would include optical logic, sensing and quantum computing. Last year, Yubo Wang and colleagues at Yale University unveiled a chip-integrated titanium:sapphire laser that utilized an indium gallium nitride pump diode coupled to a titanium:sapphire gain medium through its evanescent field. The evanescent component of the electromagnetic field does not propagate but decays exponentially with distance from the source. By reducing loss, this integrated setup reduced the lasing threshold by more than an order of magnitude. However, Jelena Vučković – the leader of the Stanford group – says that “the threshold was still relatively high because the overlap with the gain medium was not maximized”.

He writes: “Many investigators believe that PBM for brain disorders will become one of the most important medical applications of light therapy in the coming years and decades.”

He also believes it would be interesting to look at integration of other visible-wavelength lasers: “I’m expecting to see more results in the next few years,” he says.

The term 'red light therapy' often includes wavelengths in both the visible spectrum of light and the invisible spectrum of light. The visible spectrum is from 630 to 660 nanometers, whereas the invisible infrared spectrum is from 810 to 850 nanomeneters. This is considered near-infrared.

We look forward to seeing the increased benefits of this innovation in addition to the already effective red light wavelengths.

What all these wavelengths have in common is that they fall into what is known as the 'therapeutic window.' This means they have the power to treat specific conditions.

A compact, integrated titanium:sapphire laser that needs only a simple green LED as a pump source has been created by researchers at Stanford University in the US. Their design reduces the cost and footprint of a titanium:sapphire laser by three orders of magnitude and the power consumption by two. The team believes its device represents a key step towards the democratization of a laser type that plays important roles in scientific research and industry.

The researchers went on to demonstrate two things that had never been achieved before. First, they incorporated the tunability so valued in titanium:sapphire lasers into their system by using an integrated heater to modify the refractive index of the resonator, allowing it to lase in different modes. They achieved single mode lasing in a range of over 50 nm, and believe that it should be possible, with optimization, to extend this to several hundred nanometres.

That is encouraging, although more studies are needed on the effects of NIR light and brain health. Anyone suffering from a brain injury or neurological disorder should always receive treatment as prescribed by a medical professional.

Infrared dangers

In the new research, Vučković’s group fabricated their laser devices by creating monocrystalline titanium:sapphire optical resonators about 40 micron across and less than 1 micron thick on a layer of sapphire using a silicon dioxide interface. The titanium:sapphire was then polished to within 0.1 micron smoothness using reactive ion etching. The resonators achieved almost perfect overlap of the pump and lasing modes, which led to much less loss and a lasing threshold 22 times lower than in any titanium:sapphire laser used previously. “All the fabrication processes are things that can be done in most traditional clean rooms and are adaptable to foundries,” says Yang – who is first author of a paper in Nature that describes the new laser.

In many respects, red, NIR, and IR wavelengths provide similar health benefits including pain relief as well as some surprising benefits like weight loss.

The researchers achieved lasing with a $37 green laser diode as the pump. However, subsequent experiments described in the paper used a tabletop green laser because the team is still working to couple the cheaper laser into the system into the system effectively.

Since its invention by Peter Moulton at the Massachusetts Institute of Technology in 1982, the titanium:sapphire laser has become an important research and engineering tool. This is thanks to its ability to handle high powers and emit either spectrally pure continuous wave signals or broadband, short pulses. Indeed, the laser was used to produce the first frequency combs, which play important roles in optical metrology.

Infrared light therapy (over 900nm) has the deepest penetration along with positive health effects, but should be used with caution to prevent thermal damage to the body’s cells.

Nerve cells in particular appear to respond well to infrared light energy. Most studies reference infrared waves in the 800 to 900nm range.

Also, note that Platinum Therapy Lights has added a 480nm blue light to all its BIOMAX Series panels for even greater holistic effects. Now, the panels also offer custom adjustment for each spectrum, meaning users can pick and choose which set of wavelengths to use as well as their intensity.

If you’ve spent time researching red light therapy, you’ve undoubtedly seen the terms red light, near-infrared (NIR), and infrared (IR) therapy used interchangeably.

Finally, they produced a titanium:sapphire laser amplifier, something that the team says has not been reported before. They injected 120 pJ pulses from a commercial titanium:sapphire laser and amplified them to 2.3 nJ over a distance of 8 mm down the waveguide. The distortion introduced by the amplifier was the lowest allowed by the laws of wave motion – something that had not been possible for any integrated amplifier at any wavelength.

NIR waves of up to 850nm are used in red light therapy systems. IR waves are most commonly used either in clinical applications or in infrared saunas.

The three wavelengths used in BIOMAX series therapy devices. In the red range, they include 630 and 660nm. In the NIR range, they include 810, 830, and 850nm.

What sets red light apart from near-infrared is the depth to which the light photons can absorb into your body’s tissues.

What’s really interesting is that the human body reacts differently to these longer wavelengths. Instead of light, the body perceives them as infrared heat.

What is ir light used forin everyday life

They also performed a cavity quantum electrodynamics experiment with colour centres in silicon carbide using their light source: “That’s why [titanium:sapphire] lasers are so popular in quantum optics labs like ours,” says Vučković; “If people want to work with different colour centres or quantum dots, they don’t have a specific wavelength at which they work.” The use of silicon carbide is especially significant, she says, because it is becoming popular in the high-power electronics used in systems like electric cars.

While red light can do that at the skin level, if a condition is caused by inflammation deeper in the body, you’ll need the deeper penetration of NIR light to reduce the inflammation.

You may also see the acronym LLLT in reference to low-level laser therapy. In this treatment, the wavelengths and benefits are the same but the delivery is different. As the name implies, low-level laser therapy uses low-level lasers, whereas red light therapy utilizes red LED lights.

Therefore, infrared light in the NIR spectrum could be a potentially effective therapy for Alzheimer’s, Parkinson’s, and other neurodegenerative disorders

A 2014 controlled trial showed promise for the use of red light to reduce wrinkles and increase collagen protein synthesis. You can see photos of the results in the red light therapy skin trial results.
