EXPERIMENTAL VERIFICATION OF SUN-POWERED LASER TRANSMITTER.
Abstract
The feasibility of using four-level laser materials is investigated. A general expression is derived for the figure of merit ''G'' of a four-level laser in the sun-powered end-pumed configuration. (''G'' relates the laser parameters to the power input needed for threshold lasering). In a survey of possible new laser materials, two four-level types, neodymium-doped calcium tungstate and neodymium-doped glass, were determined to be promising. Thermal problems involved in cooling neodymium-doped glass are analyzed. Also, the status of the design and construction of the sun-tracking laser mount is specified. (Author)
