OPTICAL SOUNDINGS IV.

Abstract

A mode controlled Q switched ruby laser has been assembled using a Hercher resonant reflector and a saturable Q switch continuing cryptocyanine in methanol. The wavelength of the laser is varied by changing the temperature of end plates of the resonant reflector. A change of wavelength of one free spectral range (0.8A) can be obtained in this manner. A rapid scan of one free spectral range of the interior cavity of the reflector (0.1A) is possible at points in the 0.8A range by varying the pressure within the interior cavity. The output energy of the laser was typically 0.4 joules over a 30 nanosecond interval. The line width of the laser was less than 0.1A. (Author)
