A highly efficient diode-end-pumped femtosecond Yb:yttrium aluminum garnet (YAG) ceramic laser was demonstrated. Pumped by a 968 nm fiber-coupled diode laser, 1.9 W mode-locked output power at a repetition rate of 64.27 MHz was obtained with 3.5 W absorbed pump power, corresponding to a slope efficiency of 76%. Our measurement showed that the pulse duration was 418 fs with the central wavelength of 1048 nm.
我们演示了一种高效的二极管端面泵浦飞秒掺镱钇铝石榴石（Yb:YAG）陶瓷激光器。该激光器采用 968nm 光纤耦合二极管激光器作为泵浦源，当吸收泵浦功率为 3.5W 时，获得了 1.9W 的锁模输出功率，重复频率为 64.27MHz，斜率效率为 76%。我们的测量结果表明，脉冲持续时间为 418fs，中心波长为 1048nm。
