我们证明了通过双啁啾光学参量放大（DC-OPA）方案产生高能红外飞秒脉冲[Opt. Express 19，7190（2011）]。采用100 mJ泵浦激光器，在色散补偿之前，在1.4 μ m波长处获得了超过20 mJ的信号脉冲能量。记录的总输出能量为33 mJ。在进一步的能量缩放条件下，使用熔融石英棱镜压缩器将信号脉冲压缩到27 fs的几乎变换限制的持续时间。由于DC-OPA方案是有效的和能量可缩放的，设计参数为获得100 mJ级的红外脉冲，这是合适的驱动激光器的能量缩放的高次谐波产生与亚keV光子能量。(C)2015美国光学学会
We demonstrate high-energy infrared femtosecond pulse generation by a dual-chirped optical parametric amplification (DC-OPA) scheme [Opt. Express 19, 7190 (2011)]. By employing a 100 mJ pump laser, a signal pulse energy exceeding 20 mJ at a wavelength of 1.4 mu m was achieved before dispersion compensation. A total output energy of 33 mJ was recorded. Under a further energy scaling condition, the signal pulse was compressed to an almost transform-limited duration of 27 fs using a fused silica prism compressor. Since the DC-OPA scheme is efficient and energy scalable, design parameters for obtaining 100 mJ level infrared pulses are presented, which are suitable as driver lasers for the energy scaling of high-order harmonic generation with sub-keV photon energy.
