OSTI ID:6541835
This patent describes a high efficiency, diode pumped array, compact neodymium-YAG laser. It comprises: a neodymium-YAG laser rod having as front end and a back end, a housing with means holding the neodymium-YAG rod in fixed position in the housing with its front end forward, a laser diode array for pumping the neodymium-YAG rod, having an output frequency sufficiently matched to the rod to pump the rod, secured in the housing behind and in optical alignment with the rod, output coupler means including a mirrored surface forming a front end of a laser cavity, a rear mirror means forming a back end of the laser cavity, with the neodymium-YAG rod within the cavity, a frequency doubler within the laser cavity, positioned to receive the output beam of the laser rod and to halve its wavelength, doubling its frequency, and polarization control means.
