High power red laser generation by second harmonic generation with GTR-KTP crystal Download: 800次
Abstract
In this Letter, a gray-tracking-resistant—potassium titanyl phosphate (GTR-KTP) crystal is used for intracavity frequency doubling red laser generation for the first time. Under the 808 nm LD pump power of 180 W, as high as 12.5 W of red laser output is obtained with the optimum repetition rate of 7 kHz. Within the red laser power variation range between the maximum to 70%, a temperature tolerance is measured to be 35°C. The results prove that GTR-KTP should be a potential nonlinear crystal for red laser generation.
