摘要：

Micro-optic technology is used in a terawatt multipass Ti:sapphire amplifier to convert high-multimode, 532-nm radiation from an unstable resonator Nd:YAG laser into a TEM00 amplified output without sacrificing the amplifier-to-pump energy conversion efficiency. Experimental measurements and Fourier analysis of the spatial mode show a 3.8-fold increase in the peak irradiance and an order-of-magnitude improvement in the spatial contrast.
