ABSTRACT:
A total internal reflection, face pumped laser is provided, in a single head, with two (or more) generally parallel, spaced apart hosts for providing a higher average power output than the typical single host FPL. A pair of flash lamps, one each adjacent the outer surface of each host, acts as the "pumping" means for the laser and operates in effect to produce asymmetrical pumping of the respective hosts. In order to prevent exceeding the thermal stress limit and thermally inducing bending of the hosts, a system of asymmetrical cooling is provided whereby a greater flow of fluid coolant is provided the surfaces of the two hosts which are closer to the "pumping" flash lamps than to the inner host surfaces which are proximate one another.
