Red lasers are lasers that operate at wavelengths from 620 nm to 699 nm, which falls within the red spectral range of the electromagnetic spectrum. The typical emission of red lasers occurs at approximately 650 nm. This wavelength is achieved by employing different techniques like gas discharge, solid-state, or diode pumping. For some red lasers, the standard wavelength of light they emit is 632.8 nm, like the helium-neon (HeNe) lasers. HeNe lasers have been used for a long time and are commonly found in laboratories. They are great for precise measurements and aligning other lasers. The shorter red wavelengths are easier for us to see, but they can be a bit more challenging to produce efficiently.

Red lasers usually possess relatively low output power, which can vary depending on the intended application. They can be designed for continuous-wave or pulsed output and can be further adjusted for specific use through modulation. Also, red lasers often exhibit a narrow spectral linewidth, making them particularly advantageous for applications such as spectroscopy and precision measurements.

Red laser pointers are widely used for presentations, lectures, and demonstrations due to their visibility and affordability. They are used in optical communication systems to transmit data efficiently through optical fibers. These lasers are utilized in dermatology, ophthalmology, and photodynamic therapy for various medical treatments and diagnostics. The narrow spectral linewidth of red lasers makes them ideal for spectroscopic analysis and precise measurements in scientific research. They also find use in industrial settings for alignment, leveling, and positioning tasks.

The laser cavity or resonator of a red laser consists of a gain medium, mirrors, and an energy source. The gain medium is typically a material, such as a crystal or a gas, capable of emitting photons when stimulated. For red lasers, common gain media include neodymium-doped crystals or helium-neon gas mixtures.

The gain medium receives energy from an external source, such as electrical discharge or optical pumping. This energy excites the atoms or molecules within the gain medium to higher energy states. As these excited particles return to lower energy states, they emit photons with precise wavelengths characteristic of the red spectral region.

The mirrors placed at the ends of the laser cavity play a crucial role in the laser's operation. One mirror is highly reflective, allowing photons to bounce back and forth within the cavity, stimulating further emission. The other mirror, partially reflective, permits a small fraction of photons to escape, forming the laser beam.
