The Construction of a Nd:YAG Laser to Study Atmospheric Transmission Properties

摘要

A neodymium laser was constructed to be used in a study of atmospheric transmission properties of 1.06 micor-meter radiation. A Nd:YAG crystal was selected for use in the laser, and the physical and chemical properties of Nd:YAG as compiled from the literature are presented. A detailed description of the laser system design is given with the expected operational characteristics. The laser was operationally tested a number of times during which several of the design parameters were varied, but lasing action was never observed. An outline of the probable causes for failure is given in the concluding remarks. (Author)
