Abstract:
A laser system for operation at elevated temperatures, comprising:a laser media having a primary absorption band, a first optical end, a second optical end and an input port; at least one high-temperature laser diode in optical communication with the laser media and configured to operate in a prescribed temperature range being greater than or equal to 70Â° C., the laser diode being operative to generate a source beam of light in a prescribed wavelength range being matched to the primary absorption band when operated within the prescribed temperature range, the source beam of light being transmitted into the input port; at least one reflector in optical communication with the first optical end of the laser media; at least one optical coupler in optical communication with the second optical end of the laser media; an air cooling unit in fluid communication with the laser diode and operative to selectively circulate cooling air over the laser diode as needed to maintain the laser diode in the prescribed temperature range; wherein 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.
