报道了半导体激光器抽运的连续锁模镱钠共掺氟化钙(Yb,Na∶CaF2)激光器中,利用半导体可饱和吸收镜(SESAM)启动被动锁模,SF10棱镜对进行腔内色散补偿,在吸收抽运功率为9 W的条件下,采用1%的耦合输出镜,获得了脉冲宽度为406 fs,输出功率为80 mW,中心波长在1043 nm附近,重复频率为94.8 MHz的连续脉冲序列。
The demonstration of a laser diode(LD)-pumped continuous-wave(CW) mode-locked Yb,Na∶CaF2 laser is presented.By employing a semiconductor saturable absorber mirror(SESAM) for initiating the passively mode locking and a pair of SF10 prisms for the dispersive compensation,a pulse series with a duration of 406 fs and a repetition frequency of 94.8 MHz is obtained.With a 1% output coupler,the maximum of average output power centered at 1043 nm is 80 mW under the absorbed pumping power of 9 W.
