2790nm Er,Cr:YSGG laser is called erbium laser. It can be strongly absorbed by water molecules, organic matter and inorganic hydroxyapatite in solid biomass. It can use less energy to get a greater effect, This advantage is beyond the reach of other wavelengths of laser, so it not only can cut soft tissue accurately, but also can cut enamel dentin efficiently without causing thermal damage to dental pulp.The working principle of 2790nm Er,Cr:YSGG laser: transferring the energy to the coaxial water-air mixture by using the fluid dynamics, and powerful absorption of laser energy by atomized water particles with producing the expansion and acceleration. High-energy and high-kinetic energy water beams formed by high velocity arrangement, and then cutting soft tissue fastly.
2790nm Laser (Er:Cr:YSGG Laser)
2790nm Passive Q-Switch Crystal - Er,Cr:YSGG
InAs/GaAs——Using the InAs thin film on the GaAs substrate as the saturable absorber of passively Q-switch, the Q-modulated output of Er:Cr:YSGG laser is achieved, and the short pulse can be obtained.
