Abstract
A high output, compact laser having a multi-line spectral output and an internal mirror, integral resonator design is disclosed. The laser structure comprises a laser tube containing a resonant cavity, an output coupler and an active medium. A power supply and coolant assembly are coupled to the laser tube. The coolant assembly is a hybrid coolant scheme wherein one portion of the tube is cooled by circulating water coolant, while another portion or portions are cooled by circulating air. In one aspect, the laser tube includes a ceramic bore surrounded by a sheath sealed at a first end and a second end of the ceramic bore, and coolant is provided between the sheath and the bore. In a further aspect, forced air is directed over a reservoir portion of the tube. The reservoir portion may be manufactured from a metallic alloy comprised of nickel iron cobalt with copper cooling fins brazed to the reservoir to increase thermal cooling efficiency and isothermal distribution of heat.
