What is 808nm Laser

An 808nm laser is a type of infrared laser diode that emits light at a wavelength of 808 nanometers. This wavelength is invisible to the human eye, but can be detected by some cameras and sensors. 808nm lasers have various applications, such as:

• Pumping solid state lasers, such as Nd:YAG or Er:YAG
• Hair removal and skin treatments
• Fiber optic communications
• Military and industrial uses

808nm lasers can have different power levels, beam profiles, output modes, and fiber coupling options depending on the specific product and purpose. They can also be driven by different types of drivers, such as CW (continuous wave), pulsed, or modulated.

808nm laser is important because it has several advantages for different applications, such as:

• It is the optimal wavelength for stimulating mitochondria and increasing cellular energy production, which can speed up healing, reduce inflammation, and alleviate pain.
• It has a good balance of depth of penetration and low absorption by skin and blood, which makes it suitable for treating various tissues and organs.
• It can be used to pump other solid state lasers, such as Nd:YAG or Er:YAG, which have applications in dentistry, surgery, and industry.
• It can be used for fiber optic communications, military and industrial uses.

808nm laser is one of the most widely used wavelengths in laser therapy and has been proven to have beneficial effects on various conditions and diseases.

An 808nm laser compares to other wavelengths in terms of its absorption, penetration, and interaction with different tissues and materials. Some general comparisons are:

• An 808nm laser has lower absorption by skin and blood than shorter wavelengths, such as red (600-660nm) or violet (400-450nm), which makes it more suitable for deeper treatments
• An 808nm laser has higher absorption by melanin than longer wavelengths, such as infrared (900-1000nm) or far-infrared (1000-10000nm), which makes it more effective for hair removal and skin treatments
• An 808nm laser has a higher peak of interaction with mitochondria than other wavelengths, which makes it more efficient for stimulating cellular energy production and healing
• An 808nm laser can be used to pump other solid state lasers, such as Nd:YAG or Er:YAG, which have shorter wavelengths and different applications, such as dentistry, surgery, and industry

Of course, these comparisons are not absolute and depend on the specific type, power, mode, and configuration of the laser. Different wavelengths may have advantages and disadvantages depending on the application and the desired outcome.
