Abstract:
A system for amplifying a laser beam and generating an output pulse of laser light, comprising:a seed laser light source for providing a laser beam with a desired linewidth; at least one optical isolation assembly placed in the path of propagation of the laser beam for preventing reflected laser light feedback into the seed laser light source; a polarization selective assembly aligned in the path of propagation of the laser beam for directing a first polarization state of the laser beam in a first propagation direction and at least one additional polarization state of the laser beam in at least one additional propagation direction and for minimizing back reflection of one of either the first polarization state or the at least one additional polarization state of the laser beam; and at least one pumping array comprising a multiplicity of laser diodes distributed across at least one high-gain laser medium aligned in the path of propagation of either the first polarization state or the at least one additional polarization state of the laser beam for optically pumping the at least one high-gain laser medium for generating a population inversion of energy states within the at least one high-gain laser medium for amplifying the laser beam and generating an output pulse of laser light.
