Abstract : Resonator losses during different stages of generation were measured experimentally in terms of variation in the beam divergence and spot diameter at the rod end of a ruby laser. The test laser consisted of a polished cylindrical ruby rod 120 mm long and 12 mm in diameter. The laser cavity was formed by two external dielectric mirrors (each 99% reflective) placed 46 mm apart. The rod was pumped by two IPKKh 130/14 straight pulsed xenon lamps placed inside a polished cylindrical Duralimin reflector 36 mm long. The lamp input was 2900 j and the pulse threshold energy 900 j. Changes in beam divergence and beam spot diameter were recorded on film by means of a high-speed camera. Experimental data indicate that cavity losses increased with the pumping energy. (Author)
