Abstract

A powerful new technique for the generation of stable ultra-short laser pulses is reported. The basic idea of the method is to couple back a tiny fraction of the laser output into the main laser cavity. This coherent seeding signal suppresses the deleterious influence of the spontaneous emission on the pulse formation to a large extent that results in a considerable improvement of the laser output stability. Experimental results for two different laser systems are presented together with numerical simulations that serve to illustrate the principle of the technique.
