Abstract
- A new tvpe of accessible sources of ultrashort optical pulses based on the phenomenon of collective coherent recombination (superradiance) of electrons and holes in semiconductor heterostructures is proposed. The novel regime of an ultrafast operation of quantum well semiconductor lasers is analyzed, in which a quasiperiodic sequence of superradiant pulses of duration up to 30 fs and peak intenSity exceeding 100 MW/cm2 is emitted under a continuous pumping from a low-Q cavity of length of about 30-100 micrometers.<br />Pres: 6th Int Symp Nanostructures: Physics and Technology, St Petersburg, Russia. 22-26 Jun 1998. p398-401.
