Abstract

We demonstrated a CW mode-locked all solid-state Tm: CaGdAlO4(Tm: CGA) laser using SESAM as a mode-locked starting element. The laser cavity adopts an X-type four-mirror cavity structure, and the pump source is an 790nm LD. The minimum mode locking threshold of Tm: CaGdAlO₄ solid state laser was measured to be 7.54W, and when the pump power reached 14.79W, the corresponding maximum output power was 114mW at 1889nm, the repetition rate was 105.2 MHz, and the pulse width was 242.3ps. The experimental results show that Tm: CaGdAlO₄ crystal can obtain a stable 2μm picosecond pulse, which is very suitable as a gain material for 2μm ultrashort pulse lasers.
