Investigation of lasing in the direction of a streamer channel in À2Â6 semiconductors

Abstract:
An investigation was made of the generation of light in À2Â6 semiconductors along a streamer channel. The establishment of a high gain amounting to (4–6)×103 cm–1 inside a channel resulted in lasing in resonators with mirrors formed by optical inhomogeneities of a crystal. The radiation emitted in the direction of the streamer emerged from the lasing region and propagated through the bulk of the crystal, whereas in the opposite direction it traveled along an optical waveguide formed by the streamer channel. The angular distribution of the radiation in the forward direction was influenced by the Franz–Keldysh effect at the head of the streamer and by distortions of the light wave in secondary streamer channels. A considerable increase in the radiation energy in the forward direction observed at streamer velocities of at least 4×109 cm/sec was attributed to the attainment by the streamer head of a velocity higher than the group velocity of light at the wavelength of the emitted radiation.
