Abstract

PURPOSE:To ensure a maximum output energy by a method wherein the diameter of a laser beam travelling through laser amplifiers is aligned with the diameter of the cross section of laser activating solid substance housed in said amplifiers. CONSTITUTION:Located between a pulse laser oscillator 1 and a laser amplifier 4 containing laser activating solid substance 5 is an optical system 3 whose function is to align the diameter of a laser beam emitted by the oscillator 1 and the cross section diameter of the solid activating substance 5. The multiplication factor is expressed by the ratio between the cross section diameter of the substance 5 and the beam diameter, and is set at 0.96 by design. Another optical system 7 is provided between the laser amplifier 4 and 8, again to match the diameter of the laser beam to that of the cross section of the activating substance 5. This setup maximizes a laser amplifier output.
