Abstract

Multipass Ti:sapphire amplifier for the light source of DIAL was developed in an angular-multiplexing, and the characteristics of output energy and spectrum was investigated. In the two-stage multipass amplifier, we obtained the maximum output energy of 42 mJ, the amplification gain of 21 dB and the output efficiency of 26% on the wavelength of 790 nm. In the tuning range of 715 approximately 930 nm the spectral linewidth is 0.05 cm^-1. The conversion efficiencies of 35% for SHG at 780 nm and 13% for THG at 390 nm are obtained respectively. The continuous tunabilities of 240 approximately 306 nm in UV region and 360 approximately 460 nm in deep-blue region could be achieved.
