Abstract

High-peak-power, femtosecond, ultraviolet (UV) laser system has become extremely attractive for material processing applications' additional to the traditional scientific applications.2 There have been three approaches for UV high-peak power lasers. One is the nonlinear frequency conversion of the Ti:sapphire amplifier system.3,4 The other approach is KrF excimer amplifiers.5,6 The final approach is the chirped pulse amplification (CPA) laser system using UV gain medium. Ce3+:LiCaAlF6 (Ce:LiCAF) is the tunable solid- state UV laser medium with sufficient bandwidth and high saturation fluence.7,8 The fourth harmonics of Nd:YAG lasers is idea pumping source.7,8 UV pumping is not drawback owing to the recent development of new nonlinear crystals like CsLiB6O109 and Li2B4O7.10 Previously, we had reported the first UV CPA using rather small Ce:LiCAF crystal up to 30-GW level.11 The main problems for TW UV all-solid-state lasers are the scalable power-amplifier-module design that is capable to handle high pulse energy in UV region. In this paper, we will report a coaxially-pumped large-aperture power-amplifier module. Moreover, the detailed design parameters for further energy scaling are successfully evaluated.
