摘要
报道了稳定连续锁模皮秒Yb:LSO激光脉冲的产生研究。实验中增益介质采用原子数分数为5%掺杂的Yb3+Lu2SiO5(Yb:LSO)激光晶体, 利用半导体可饱和吸收镜(SESAM)作为被动锁模元件。在2 W抽运功率下, 获得了平均功率70 mW的Yb:LSO激光稳定锁模输出, 重复频率69.8 MHz;实际测得脉冲宽度为3.6 ps, 脉冲中心波长可分别运转于1047 nm及1066 nm。
Abstract
A stable continuous-wave mode-locked picosecond Yb:LSO laser was demonstrated. The 5% doped Yb3+Lu2SiO5 (Yb:LSO) crystal was used as the laser medium, and a semiconductor saturable absorber was employed to realize mode-locking. With the pump power of 2 W, the output picosecond pulse power is 70 mW, at the repetition rate of 69.8 MHz. The measured pulse width is 3.6 ps, and the center wavelength can be at 1047 nm or 1066 nm.
