摘要
全固态被动锁模振荡器具有脉冲能量高、稳定性好的特点,研究了高功率掺钕钒酸钇(neodymium doped yttrium vanadate,Nd:YVO_(4))参量克尔透镜锁模振荡器。该振荡器中的参量克尔效应来自于光在三硼酸锂(lithium triborate,LBO)中产生的级联二阶非线性效应。结果表明,参量克尔透镜锁模振荡器能够实现自启,获得了输出的总平均功率为20 W、重复频率为79.3 MHz、脉冲宽度为22 ps的激光。
An all-solid-state passive mode-locked oscillator has the characteristics of high pulse energy and good stability.A high-power neodymium-doped yttrium vanadate(Nd:YVO_(4))parametric Kerr lens mode-locked oscillator is researched,in which the parametric Kerr effect is from the cascaded second-order nonlinear effect produced by light in lithium triborate(LBO).The results show that the oscillator can be self-started with a total average power of 20 W,repetition rate of 79.3 MHz and pulse duration of 22 ps.
