ABSTRACT: High-peak and high-average power diode-pumped solid-state laser is one of the most useful pump sources for high-intensity laser-driven applications as well as inertial fusion energy. Zig-zag slab scheme has a potential to scale up to the orders of giga-watt in peak power and kilo-watt in average power simultaneously, because of its availability of larger aperture and higher cooling capability. Diode-pumped Nd:YLF regenerative ring amplifier is amplified by a double pass through the left slab amplifier up to 3 J, before the beam is optically expand to the full aperture of a slab amplifier by the anamorphic telescope, and it is cut out by the rectangular serrated aperture of 0.8 cm wideĆ4.8 cm high. The laser pulse passes the slabs four times each in two symmetrical paths. Finally the output pulse is ejected by a thin-film polarizer.
