We demonstrate a successful recompression of 4.5 mJ, 30 fs femtosecond pulses from a Ti:Sapphire oscillator amplified in a ring multi-pass optical parametric chirped pulse amplifier using beta-barium borate crystal pumped by a commercial frequency doubled Nd:YAG laser. Pulses with duration close to the Fourier transform limit were obtained.
我们展示了通过使用商用倍频Nd:YAG激光器泵浦的β-硼酸钡晶体,在环形多程光学参量啁啾脉冲放大器中对来自钛宝石振荡器的4.5 mJ、30 fs飞秒脉冲进行成功再压缩。获得了持续时间接近傅里叶变换极限的脉冲。
