Abstract: A quasi-cw 290-kW diode-pumped zig-zag slab laser has been developed in order to demonstrate a concept of the IFE driver. Thermally managed glass slab has yielded an amplifier gain of 10. 8.74 J and 5.17 J per pulse at 1 Hz and 10 Hz, respectively, with a 5 times diffraction limited beam quality were achieved using a multi-pass amplifier architecture. This result indicates that diode-pumped solid-state laser based on Nd:glass material can be a candidate of the high energy and high average power driver for the IFE and related applications.
