Abstract

A Nd:glass laser based on a novel design delivers up to 120J energy pulses with a quasi-flat-top spatial profile at a 0.1Hz repetition rate. The laser output is frequency-doubled with 50% efficiency and used to pump Ti:sapphire amplifiers. The developed design is perspective for use in the currently contemplated next step in ultra-high-intensity laser development.

Pump laser layout. Nd:YLF, Nd:YLF-rod laser head; 16 mm glass, 16 mm -diameter rod laser head based on athermal phosphate glass (QX-Nd, Kigre); FR, Faraday rotator; KDP, harmonic generator; Ti:S1 and TiS2, Ti:sapphire amplifiers (beam size 1 and 2 in , respectively); GM, Gaussian mirror output coupler; DM, dichroic mirror; P, polarizer. All relays consist of a pair of lenses with evacuated (no pump vacuum necessary) glass tube in between. Double pass amplifiers (including corresponding harmonic generators) of stage two are shown only symbolically. They have the same layout as double pass amplifiers of stage one shown in the figure, except the rod diameter ( 25 mm for the stage two), the beam size, and the harmonic generators size. The oscillator Q-switch and the relay, imaging the oscillator beam to the entrance to 16 mm glass heads, are not shown.
