ABSTRACT:
A high power end-pumped laser system for use with a regenerative amplifier includes an assembly for generating a plurality of collimated laser beams and a focusing element for focusing the plurality of laser beams onto a common focal volume. To generate the plurality of collimated laser beams, the assembly employs an array of diode lasers and an array of collimating microlenses. The microlens array is positioned relative to the laser diode array to place each collimating microlens in the beam path of a respective diode laser. The resultant plurality of collimated laser beams are emitted from the assembly substantially parallel to each other and they are all then passed through a cylindrical collimating lens with the result that the beams are collimated in two planes. The output of the cylindrical collimating lens is then focused by a lens to a focal volume. For operation of the system, the focal volume is located in a laser medium to allow the medium to be end-pumped. To prevent thermal instability in the medium, and to maximize the efficiency of the pumping action, the plurality of laser diodes are simultaneously pulse activated for only approximately four hundred microseconds during each millisecond of operation (400 .mu.s/ms).
