Paper Abstract

A new pump-shaping scheme for a LD face-pumped Nd:YAG slab laser amplifier is proposed, aiming to achieve uniform pump distributions. Plano-concave cylindrical mirror arrays are used to homogenize the pump distributions in the LD slow axes, and meanwhile optical-waveguide structures are used for the LD fast axes. Simulations based on ray tracing method indicate that the scheme effectively realizes uniform pump intensity distributions. The fluorescence distributions and small signal gains at different locations both verify the pump uniformity reaches higher than 90%.
