摘　　要：A diode-pumped mode-locked(ML)Tm,La:CaF_(2) crystal laser is reported in this paper.This laser system delivers stable con tinuous-wave ML pulses,achieving a maximum output power of 143 mW at a fundamental frequency of 96.2 MHz.Moreover the signal-to-noise ratio in the stabilized single-pulse regime reaches as high as 75 dB.The central wavelengths of the lase are located at 1886.5 and 1886.7 nm,which further advances the development of ultrafast lasers in the water absorptio band of 1.8–1.9μm.
