Generation of powerful submicrosecond laser pulses and their use in laser gasdynamics: observation of an optical detonation wave along the beam and penetration of the beam into an absorbing gas medium, generation wave, motion of beam or of beam focus
Askar'yan G.A., Manzon B.M.
We describe generation of high-power laser submicrosecond pulses with the aid of a self-bleaching metallized film in a resonator. The existence of a film-bleaching wave that is caused by derealization of the radiation and travels with a speed of 107 cm/sec is demonstrated, and the possibility of scanning and motion of the focus is estimated. Applications of submicrosecond laser in laser gas dynamics are cited. An optical detonation wave along the beam and penetration of the beam into an absorbing gas medium are observed.
