Paper Abstract

An designed output coupler used for the dispersion compensation in Cr:LiSAF femtosecond lasers is reported. It is composed of 50 alternating Ta2O5 and SiO2 layers whose thicknesses are obtained by computer optimization to provide low transmittance and as little as possible group delay dispersion. The optimized output coupler has continuous low transmittance of 1% and group delay dispersion of 0 ±6fs2 from 750nm to 900nm, which can meet the need of dispersion compensation in Cr:LiSAF lasers.
