Abstract
A theoretical analysis is made of a laser system based on a regenerative amplifier and capable of generating trains of pulses of variable amplitude. The time dependence of the gain is obtained for the rise of energy required to achieve a very strong compression (implosion) of a target by laser radiation. An analysis is made of a combined method for varying the gain by an electro-optic switch and a saturable filter. Numerical estimates are obtained for regenerative amplifiers with unstable and plane-parallel resonators in which the active element is made of neodymium-doped glass or yttrium aluminum garnet (YAG:Ne). This method may be useful in those cases when a train of pulses with a specified energy variation has to be generated.
