Simulations of Target Interactions with Pulsed, High-Energy Solid State Lasers

摘要

In a solid-state heat capacity laser (SSHCL), waste heat is stored in the lasing slabs, minimizing temperature gradients and optical distortions. After the maximum number of pulses is reached, the slabs are rapidly exchanged with cool slabs. During the past several years, our laboratory at LLNL has built a number of SSHCLs, demonstrating powers beyond 10 kW. In this paper, we model target interactions produced by a 10 kW device (500 J/pulse and 20 Hz), operating at a wavelength of 1.053 μm. The laser contains 9 Nd:glass slabs pumped by flashlamps.
