We report the amplification of three-cycle, 8.5 fs optical pulses in a near-infrared noncollinear optical parametric chirped-pulse amplifier (OPCPA) up to energies of 80 mJ. Improved dispersion management in the amplifier by means of a combination of reflection grisms and a chirped-mirror stretcher allowed us to recompress the amplified pulses to within 6% of their Fourier limit. The novel ultrabroad, ultraprecise dispersion control technology presented in this work opens the way to scaling multiterawatt technology to even shorter pulses by optimizing the OPCPA bandwidth.
我们报道了在近红外非共线光学参量啁啾脉冲放大器（OPCPA）中对三周期、8.5飞秒光脉冲进行放大，放大后的能量高达80毫焦。通过反射光栅和啁啾镜展宽器相结合的方式改进放大器中的色散管理，使我们能够将放大后的脉冲压缩至其傅里叶极限的6%以内。这项工作中提出的新型超宽、超精确色散控制技术，为通过优化OPCPA带宽将多太瓦技术扩展到更短脉冲开辟了道路。
