摘要
探索了此领域的一种新型技术路线级联倍频压缩，重点分析了级联倍频压缩的物理思想与过程，在再次压缩技术条件的基础上，利用I类二倍频BBO晶体，对波长为800 nm的无啁啾基频光进行了原理验证实验，实现了2~3倍的压缩比，从而证明此技术的可行性，此为下一步的详细研究奠定了基础。
Abstract
A new technology namely cascaded frequency-harmonic and pulse-compression is investigated. Based on the analysis of re-compression theory, process and conditions, and with the type-I BBO crystal for second harmonic generation (SHG), the nonchirped fundamental light (namely 1ω, 0.8-μm-wavelength) is compressed again and the compression-ratio is up to 2~3, which proves that the technology is effective and practical. Based on the study, the further study will be carried out in the future.
