Efficient TM: Ylf Crystal with Linearly Polarized Laser Output

Product Description

Products Description
Tm:YLF Tm: YLF crystal is a negative uniaxial crystal with a negative temperature coefficient of refractive index, which can offset part of thermal distortion, so the output beam quality is high. The pumping wavelength is 792nm, and the linearly polarized laser light of 1.9μm is output in the a-axis direction. The c-axis output is non-linearly polarized light. Selecting the appropriate crystal size and doping concentration can obtain high-power laser output, and it is an important pump source laser crystal for mid-wave infrared lasers. Main features: Linearly polarized laser output The thermal effect of laser operation is small Cross relaxation Efficient Suitable for diode pumped
