In a carbon dioxide generator, a chamber is filled with carbon dioxide, helium, and nitrogen. The carbon dioxide is the medium used to generate the laser beam, and the other gases support and stabilise the process.

Laser light consists of parallel beams of light on the same wavelength. Compared with the light from a torch, this allows the beam to be focused down to an extremely small point.

The photons bounce between a rear mirror and a front mirror to build the laser beam up to its full intensity. The front mirror is semi-transparent and allows a certain number of photons to pass through. However, the majority of the photons are reflected back to maintain the full intensity of the generator.

This type of generator follows the basic principle of how a laser beam is generated, whereby a medium is “pumped” with energy to then emit photons when the medium returns to its natural state.

Although all laser generators work in this way, they have different ways of supplying energy, known as pumping, and different types of atoms used for the excitation, i.e. different laser media.

Pumping is done using relatively cheap diode lasers which insert laser light into the fibre. The light is directed towards and reflected against the outer sheath and repeatedly passes through the fibre core, which raises the electrons of the medium to a higher energy level (excitation), which are then stimulated to return to their basic state (emission), which releases the beams of light (photons).

In simple terms, a laser uses light to transmit heat very precisely. The same principle applies to modern lasers as when laser technology was discovered almost sixty years ago. Over thirty years, Permanova has worked to refine the technology and make it easy and safe to use. For those who want to delve into the underlying physics and technology, there is a lot of information to feast on below.

No special drivers are needed, use your operating system's built in USB camera support for instant image/video data. Works with Mac, Windows, Linux, etc. Note this is not going to give you iPhone-quality output with HDR and low-light vividness, it's a basic camera that is inexpensive and compact, but should work for many vision recognition, and photo-taking situations.

The word LASER is the acronym of Light Amplification by Stimulated Emission of Radiation, which is essentially an explanation of the process.

Pumping takes place by way of electrical discharges to raise the electrons of the medium to a higher energy level (excitation), which are then stimulated to return to their basic state (emission), which releases the beams of light (photons).

If you buy less than a full reel, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. If the piece comes from the end of the reel, the connector may be on the output end of the strip!

This type of generator follows the basic principle of how a laser beam is generated, whereby a medium is “pumped” with energy to then emit photons when the medium returns to its natural state.

In this way, the laser beam is generated in the direction of the fibre and is then emitted and transmitted via the fibre to the point of application.

The photons let through form the laser beam that is then directed via optical mirrors and lenses to the point of application.

This type of generator follows the basic principle of how a laser beam is generated, whereby a medium is “pumped” with energy to then emit photons when the medium returns to its natural state.

This was probably originally designed for use inside monitors or products that need a simple video sensor with 640x480 output and 8mm x 25mm x 4.5mm PCB. Inside is a GC0307 image sensor SM3762 camera-to-USB adapter chip wired up to a 1mm pitch connector for power/ground/D+/D-. An adapter cable that converts this to a USB A port is included, but of course you can cut it for direct wiring.

This type of emission is not desirable in the context of lasers as, ideally, photons with a parallel direction are required. This can be achieved by “pushing” the electron down to its original level using another photon. This is called stimulated emission and results in the photons emitted having exactly the same direction as the one that pushed the electron down. These in turn push down additional excited electrons, which creates a chain effect of emissions and subsequently builds up the energy in the laser beam.

Pumping takes place by way of flashing light to raise the electrons of the medium to a higher energy level (excitation), which are then stimulated to return to their basic state (emission), which releases the beams of light (photons).

This unbelievably small USB camera is great for embedded projects that have USB host support for standard UVC cameras, and not a lot of space. Sure you could get a desktop USB camera at any tronix shop, but would it be so incredibly small?

In order to create a photon, with both wave and particle properties, external energy must be added to an atom. This raises the energy level of one or more electrons, resulting in their jumping up one or more electron shells. This is called excitation.

The photons bounce between a rear mirror and a front mirror to build the laser beam up to its full intensity. The front mirror is semi-transparent and allows a certain number of photons to pass through. However, the majority of the photons are reflected back to maintain the full intensity of the generator.

Cost. In the 1990s, laser sources were bulky and relatively expensive to buy. A lot has happened since then. Modern industrial lasers are rarely bigger than a large refrigerator. The cost per kilowatt is a third of what it once was, and uptime is in excess of 99%.

In a fibre laser, the medium is usually an erbium-doped fibre. The fibre itself consists of three layers – the inner ytterbium-doped core, a transparent middle layer, and the outer sheath.

Since this state is not a natural state for the atom, the electron eventually jumps back to its original level and emits the excess energy in the form of a photon in a random direction. This is called spontaneous emission.

Adafruit NeoPixel Digital RGB LED strips come to us in 4 or 5 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires as shown in the picture below. If you order a full 4 or 5 meters, you get the full reel with both connectors installed.

Several types of fibre generators are available. For example, in some cases the beam is bounced between mirrors at the ends, or the pumping is done by way of one or more inlets along the length of the fibre instead of from the end.
