Optical superradiance and pulsed IR generation in quantum - well heterolasers under cw pumping

摘要

We investigate possible regimes of one - or two - color mode superradiance of femtosecond optical pulses and accompanying parametric generation of infrared pulses, which contain a few periods of field oscillations, in quantum - well heterolasers of micrometer length under cw pumping. The effects of strong magnetic field and inhomogeneous broadening of electronic levels of dimensional quantization in quantum wells are analyzed.
