论文摘要
光电电极电子源的一个备受追捧的目标是通过临时塑造入射射击激光脉冲来提高性能。狭窄的带宽，短波长和皮秒脉冲持续时间使采用常规光谱脉冲塑形技术具有挑战性。我们提出了一种新型，有效的强度 - 振动型塑形技术，该技术通过相反的频率频率混合在非线性上转换过程中实现。我们还提出了LCLS-II光注射器的数值案例研究，其中横向电子发射量至少提高了25％。
A long sought-after goal for photocathode electron sources has been to improve performance by temporally shaping the incident exitation laser pulse. The narrow bandwidth, short wavelength, and picosecond pulse duration make it challenging to employ conventional spectral pulse shaping techniques. We present a novel and efficient intensity-envelope shaping technique achieved during nonlinear upconversion through opposite-chirp sum-frequency mixing. We also present a numerical case-study of the LCLS-II photoinjector where transverse electron emittance is improved by at least 25%.
