Theory of generation of sub-10-ps pulses in a cw solid-state laser with a semiconductor passive switch and self-focusing in coherent-interaction conditions

摘要

An analysis made on the basis of the theory of the self-consistent field shows the possibility of production of sub-10-fs soliton-like pulses in a solid-state laser with a semiconductor switch in the absence of the self-focusing mechanism of mode-locking. The self focusing mechanism of mode-locking leads to the formation of a sech-shaped pulse of limiting duration. In this case, restrictions imposed on the minimum modulation depth in a semiconductor switch that provides self-starting USP generation are lifted.
