TIME RESOLVED SPECTROSCOPY AND INTERFEROMETRY ON LASER RODS, APPENDIX I. A STUDY OF THE EMISSION FROM A TRAVELING WAVE RUBY LASER, APPENDIX II.

Abstract

Investigations carried out on solid state laser phenomena are described. High speed photography of near field phenomena in the radiation from several ruby lasers shows the very complex distribution of intensity both in space across the face of the ruby and in time ('spiking'). Time resolved interferometry was carried out on laser rods under pump conditions, but without lasing, to observe effects of heating by the pump radiation. Evidence of spectral narrowing in the output of a traveling wave ruby laser is presented. A comparison of equivalent traveling and standing wave cavities shows that for similar excitation, spectral narrowing of better than a factor of four can be achieved. However, multimoding in this experimental arrangement is still strongly evident. Results of preliminary experiments in 'Q' switching the traveling wave cavity are presented.
