100 kW laser diode module for DPSSL fusion driver

High peak power laser diode arrays are required for pumping solid-state lasers as the laser fusion driver. We report successful achievement of a 100 kW peak power diode laser module as the pump source of 10 J/spl times/10 Hz Nd:glass slab laser in order to verify a small scale experiment of the diode-pumped solid-state laser (DPSSL) driver for inertial fusion energy development. The AlGaAs laser diode structures were grown by the MOCVD method and employed the quantum well structures.
