We experimentally demonstrated a passively mode-locked picosecond Tm,Ho:LiLuF4 laser with low threshold and high efficiency. The stable continuous-wave (CW) mode-locked operation with 12 ps pulse width is obtained by using a five-mirror cavity structure and semiconductor saturable absorber mirrors (SESAMs). The results indicate that the laser offers a mode-locked threshold power of 1.03 W and maximum mode-locked output power of 350 mW. The repetition rate of mode-locked pulse sequence is 98.04 MHz, corresponding a maximum single pulse energy of 3.51 nJ.
