We report on a diode-pumped passively mode-locked Yb:Lu(1.5)Y(1.5)Al(5)O(12) (Yb:LuYAG) laser for the first time to our knowledge. With the mixed crystal of Yb:LuYAG as gain medium, the mode-locked laser generated 2.2 W of average output power with a repetition rate of 83.9 MHz and pulse duration of 2.4 ps at the wavelength of 1030 nm. In order to obtain higher output power, the output from the mode-locked oscillator was further amplified to 8.5 W by two-stage single-pass amplifiers. The high-power picosecond laser is very useful for applications such as pumping of midinfrared optical parametric oscillators, material microprocessing, and UV light generation.
据我们所知，我们首次报道了一种二极管泵浦被动锁模Yb:Lu(1.5)Y(1.5)Al(5)O(12)（Yb:LuYAG）激光器。以Yb:LuYAG混合晶体作为增益介质，该锁模激光器在1030nm波长处产生了2.2W的平均输出功率，重复频率为83.9MHz，脉冲持续时间为2.4ps。为了获得更高的输出功率，锁模振荡器的输出通过两级单程放大器进一步放大至8.5W。这种高功率皮秒激光器对于诸如泵浦中红外光学参量振荡器、材料微加工和产生紫外光等应用非常有用。
