EYE SAFE LASER CRYSTAL - An Overview
EYE SAFE LASER CRYSTAL - An Overview
Blog Article
Based on the laser’s power and exposure length, these accidents can range from insignificant discomfort to sizeable eye injury.
Just one Major software is wind velocity measurement. Substantial-power LIDAR units employing Tm:YAG crystals can venture laser beams to significant altitudes to evaluate wind velocity and route with extraordinary accuracy.
We report over a superior average energy and higher repetition price nanosecond pulsed eye-safe KGW Raman laser intracavity pushed by an acousto-optic Q-switched 1342 nm two-crystal Nd:YVO4 laser. Having benefits of the thoroughly chosen two-composite-laser-crystal configuration, the extensively optimized gate-open time of acousto-optic modulator and the ingeniously built U-formed resonator, substantial energy and efficiency enhancements and excellent method matching are actually enabled.
A non-critically stage matched KTA optical parametric oscillator intracavity pumped by an actively Q-switched Nd:GYSGG laser with twin signal wavelengths
The principle of emission wavelengths lies in the really core of laser technologies, dictating many parameters such as penetration depth, power density, and safety steps. It’s no coincidence that Yb:Er:glass and Tm:YAG, two popular laser crystals, are famous for their eye-safe wavelengths.

Both crystals have their exclusive strengths. The selection concerning the two is determined by the specific application demands.
When we click here converse of Yb:Er:glass, we check with a laser crystal that primarily operates in an eye-safe spectral region of all-around one.5 µm. This wavelength location doesn’t just surface appealing around the area; it carries sizeable implications for just a big selection of purposes.
The battle involving these two forms of laser crystals is centered about their emission wavelengths, get, and purposes. Allow’s dissect The 2 and find out how they square off in opposition to one another.
This ensures lessened danger of retinal hurt, featuring a safer option for a variety of apps. Further than the safety element, Thulium-doped achieve media also stick out because of their superior performance.
: Holmium-doped acquire media offer great functionality in the clinical area because of their superior absorption coefficient in drinking water. This enables for specific energy shipping into the target tissue, decreasing the probable damage to surrounding parts.
