Laser Crystal Absorption Coefficient Measurement System Model Number: STA-CAC
In the process of crystal production, due to the purity of the material, production technology and other reasons, the light absorption uniformity of the crystal will be affected, thus affecting the crystal efficiency; After absorbing electromagnetic waves, the electromagnetic wave energy is converted into heat energy, which causes the internal temperature of the material changes , so that the internal heat absorption of the crystal is nonuniformity, resulting in large deformation. Therefore, it is of significant guiding principle and pratical value to study the effect of optical absorption coefficient of laser crystal material on laser output and frequency conversion efficiency.
Features
- Real-time laser power monitoring via dual-optical path design
- Wavelength selection based on sample characteristics
- Customizable sample holders
- Intuitive, storable results for analysis
- Simple and user-friendly operation
Laser Crystal Absorption Coefficient Measurement System
Experimental Example
The absorption coefficient of the laser crystal is determined by monitoring the laser power before and after the sample in real time using a dual-beam differential method. The sample is rotated to find the position of minimum loss (or optimal alignment) for measurement.
