High-Pulse-Energy Ultraviolet Ce³⁺:LiCaAlF₆ Laser Oscillator with Newly Designed Pumping Schemes

Abstract

Using a large Ce 3+ :LiCaAlF 6 (Ce:LiCAF) crystal, 60 mJ pulses were generated directly from a quasi-coaxially pumped Ce:LiCAF laser. In addition, a new noncollinear Brewster-angle-pumping disk oscillator scheme was demonstrated for further output-energy scaling.
