Development of phase delay mirrors for femtosecond laser systems
摘要
Abstract
Phase delay mirrors were designed and prepared to regulate femtosecond laser systems'group-delay dispersion(GDD).This paper systematically investigates the principle of compensating group-delay dispersion by phase-delay mirrors.Nb2O5 and SiO2 were used as the materials with high and low refractive indices.The group-delay dispersion curves were smoothed out by pairing the phase-delay mirrors with their complementary mirrors.The phase-delayed mirrors with phase modulation data of-800 GDD were prepared,and the reflectivity reached more than 99％in the range of 900 nm-1100 nm.The bandwidth adjustment problem of femtosecond laser systems is solved to meet the requirements of femtosecond lasers.关键词
