Abstract

We report a 100 W, 20 mJ, 1-ps, all-Yb:YAG thin-disk regenerative amplifier seeded by a microjoule-level Yb:YAG thin-disk Kerr-lens mode-locked oscillator. The regenerative amplifier is implemented in a chirped pulse amplification system and operates at an ambient temperature in air, delivering ultrastable output pulses at a 5 kHz repetition rate and with a root mean square power noise value of less than 0.5%. Second harmonic generation of the amplifier's output in a 1.5 mm-thick BBO crystal results in more than 70 W at 515 nm, making the system an attractive source for pumping optical parametric chirped pulse amplifiers in the visible and near-infrared spectral ranges.

摘要

我们报道了一种由微焦耳级的镱钇铝石榴石（Yb:YAG）薄片克尔透镜锁模振荡器作为种子源的100瓦、20毫焦、1皮秒全镱钇铝石榴石薄片再生放大器。该再生放大器应用于啁啾脉冲放大系统中，在空气中的环境温度下运行，以5千赫兹的重复频率输出超稳定的脉冲，其均方根功率噪声值小于0.5%。放大器输出在一块1.5毫米厚的硼酸钡（BBO）晶体中进行二次谐波产生，在515纳米处产生超过70瓦的功率，使该系统成为在可见光和近红外光谱范围内泵浦光学参量啁啾脉冲放大器的有吸引力的光源。
