摘要
基于高反射膜层和Gires-Tournois(G-T)腔, 优化设计了一对低振荡高色散镜。该色散镜对的中心波长为800 nm, 能够在680~920 nm的带宽范围内提供-200 fs2的平坦的群延迟色散。基于双离子束溅射工艺, 利用Nb2O5和SiO2制备了低振荡高色散镜对, 并将其应用于800 nm钛宝石激光器系统。通过高色散镜对2次,100.8 fs 激光脉冲被压缩至19 fs。
Abstract
Based on high-reflection layers and the Gires-Tournois (G-T) cavity, a low oscillation and high dispersion mirror pair is optimized and designed, whose central wavelength is 800 nm and which can provide a constant group delay dispersion of -200 fs2 over a bandwidth of 680-920 nm. The low oscillation and high dispersion mirror pair is prepared by using Nb2O5 and SiO2 based on the dual ion beam sputtering process, which is used in the 800 nm Ti∶sapphire laser system. The laser pulse can be compressed from 100.8 fs to 19 fs when the pulse travels through the high dispersion mirror pair for twice.
