Abstract
A transversely pumped solid state laser includes: a solid state gain medium having thickness, width and longitudinal dimensions; means for forming a laser cavity with the medium for generating a laser beam along the longitudinal dimension; and a semiconductor laser pump source for directing a collimated pump beam to the medium along the width dimension transversely to the longitudinal dimension constrained toward the center of the medium and having a width which is substantially shorter than the longitudinal dimension of the medium for spacing the edges of the collimated beam away from the longitudinal ends of the medium to reduce thermomechanical distortion of the longitudinal ends of the medium and consequent distortion of the laser beam.
