摘要：

The diode-purnped slab laser for inertial fusion energy driver has been demonstrated, which produces the 1053-nm output energy of 10J at 10 Hz. The glass slab laser amplifier has been pumped by quasi-CW 290-kW AlGaAs laser-diode arrays at 803 nm. The optical system can compensate for thermal effects by use of zigzag optical propagation, image-relayed telescope, and 45 degrees Faraday rotator. The output energy of 10.6 J at 1 Hz with the optical-to-optical conversion efficiency of 19.9% has been successfully obtained. Also, the 10-Hz operation has been performed with ail output energy of 5.1 J. (c) 2006 Wiley Periodicals, Inc.
