%X 本实验以InGaAs半导体可饱和吸收镜(SESAM)作为锁模启动元件在Tm:Lu3Al5O12 (Tm:LuAG)激光器中实现了双波长连续锁模运转。采用1.5%，3%和5%的输出镜，当腔内未插入SESAM时，最大连续输出功率分别为680 mW、1.09 W和1.4 W。当腔内插入SESAM后，仅在1.5%输出镜下实现了稳定双波长连续锁模运转，对应的输出波长为2020.3 nm和2023.2 nm，脉冲宽度为63.2 ps，重复频率为97.9 MHz，最大平均输出功率135 mW。结果表明：Tm:LuAG晶体是2 μm波段优良的双波长晶体。<br />
In this experiment, an InGaAs semiconductor saturable absorber mirror (SESAM) is used as a mode-locked starting element to realize dual-wavelength continuous-wave (CW) mode-locked operation in Tm:Lu3AL5O12 (Tm:LuAG) laser. With 1.5%, 3% and 5% output mirrors, the maximum CW output power is 680 mw, 1.09 w and 1.4 W respectively. When SESAM is inserted into the cavity, a stable dual-wavelength mode-locked operation is realized only with 1.5% output mirror. The corresponding output wavelengths are 2020.3 nm and 2023.2 nm; the pulse duration is 63.2 ps; the repetition rate is 97.9 MHz; the maximum average output power is 135 mW. The results show that Tm:LuAG crystal is an excellent dual-wavelength crystal in 2 μm band.
