Abstract

Recently it has been demonstrated that a modelocked argon laser operated in the superfluorescent regime, can generate pulses with peak power in the kilowatt region (1, 2). These pulses can be exploited to generate a variety of nonlinear effects. In particular, coupling the pulses into a single mode fibre generates strong stimulated Raman emission in the region of 529nm. This Raman emission precludes the compression of the incident pump pulses by conventional grating pulse compression techniques, but can be used to advantage to generate subpicosecond pulses in a fiber Raman laser.
