ABSTRACT:
A reliable, low cost, light weight, CW pumped Nd:YAG laser with optional Q-switching is provided with a rail for the laser optics that isolates the optical axis from movement of the laser head housing. A laser pot is provided with a housing and quickly detachable cover both molded of a resin that is impervious to water, optically opaque, possesses low thermal deformation, high dielectric strength and resistance to damage by light and UV radiation. The pot is formed with a cavity lined by molded reflectors and divided by a septum interposed between the laser rod and lamp. The lamp is removable with the cover and is readily coupled with the lamp sockets designed for accepting variations in lamp manufacturing tolerances. The power supply for the laser resonator is transformerless and parallel triggering is employed for the lamp. The cooling system is provided with a water immersed heat exchanger defined by a coated copper tube that prevents ionic action.
