Thermal Effect in KTP Crystals During High Power Laser Operation

         

摘要

We report on the theoretical and experimental studies of the thermal effect of the KTP crystal during rnhigh power operation. From the dependence of the refractive index temperature coefficients on wavelength, the rndependence of the optimum phase-matching angles on temperature is derived. In the experiment, the angle of rnthe frequency-doubled KTP crystal is tilted to compensate for the thermal effect and to obtain △φ = 0.7° when rnthe green laser output power is 30 W and the KTP crystal temperature is about 80°C. We obtained the highest rnstable output power greater than 40 W with an L-shaped flat-flat intracavity frequency-doubled Nd:YAG laser.rnThe experimental results are very consistent with the theoretical analysis.
