我们报告了一种双啁啾光学参量放大(DC-OPA)方案的优化和表征(2011年OPT.快线197190)。当泵浦脉冲能量增加到100mJ时，(信号+闲置)总输出能量超过30mJ，转换效率超过30%。通过原理验证实验，验证了DC-OPA方案进一步提高输出能量的可行性，获得了30%~40%的转换效率。中心波长为1.4微米的信号脉冲被压缩到27飞秒(半高宽)，非常接近变换极限脉冲宽度25飞秒。由于DC-OPA方案对于产生具有良好定标能力的高能红外脉冲是有效的，因此详细讨论并给出了获得百兆焦级甚至焦耳级红外脉冲的设计参数。
We report optimization and characterization of a dual-chirped optical parametric amplification (DC-OPA) scheme (2011 Opt. Express 19 7190). By increasing a pump pulse energy to 100 mJ, a total (signal + idler) output energy exceeding 30 mJ was recorded with higher than 30% conversion efficiency. The feasibility of further increasing the output energy to a higher scale using the DC-OPA scheme was confirmed by a proof-of-principle experiment, in which 30%-40% conversion efficiency was observed. The signal pulse with the center wavelength of 1.4 mu m was compressed to 27 fs (FWHM), which was very close to a transform-limited pulse duration of 25 fs. Since the DC-OPA scheme is efficient for generating high-energy infrared (IR) pulses with excellent scaling ability, the design parameters for obtaining hundred-mJ-level and even joule-level IR pulses are discussed and presented in detail.
