A laser system for operation at elevated temperatures with minimal cooling requirements. The laser system comprises a laser media having first and second optical ends and an input port. The laser system further comprises at least one high-temperature laser diode which optically communicates with the laser media and is operative to generate a source beam of light which is transmitted into the input port of the laser media. Optically communicating with the first optical end of the laser media is at least one reflector, while optically communicating with the second optical end of the laser media is at least one optical coupler. The laser media, the reflector and the optical coupler are configured to form a laser resonator operative to generate a laser beam which is transmitted through the optical coupler.

Solid-state laser system using high-temperature semiconductor diode laser as an optical pump source

An eye-safe laser operating at high efficiency, pulse repetition rate and power output is described. The laser comprises a diode-array pumped laser having a pumping wavelength range which produces a polarized output beam. The output beam passes through a nonlinear tunable parametric converter crystal having X, Y, and Z principal axes. Noncritical phase matching is produced in said laser by phase matching for a beam propagation parallel to a principal axis which results in a high efficiency of laser operation. The nonlinear tunable parametric converter crystal converts the wavelength of an otherwise unsafe laser beam output to one that is harmlessly absorbed by the human eye.
