Comparative study of high power Tm:YLF and Tm:LLF slab lasers in continuous wave regime.

We report on Tm:YLF and Tm:LLF slab lasers (1.5 x 11 x 20 mm) end pumped from one end with a high-brightness 792 nm laser diode stack. These two lasers are compared under identical pump conditions in continuous-wave regime.
