WebThen the passive losses of the cavity mode might be compensated by Brillouin gain when Stimulated Brillouin scattering (SBS) initiated in an opti- pump intensity is increased. cal cavity is an attractive phenomenom to generate narrow Let’s consider the temporal amplitude evolution u(t) of the linewidth lasers [1]. Laser linewidth from high-power, high-gain pulsed-lasers, in the absence of intracavity line narrowing optics, can be quite broad and in the case of powerful broadband dye lasers it can range from a few nm wide to as broad as 10 nm. Laser linewidth from high-power high-gain pulsed laser oscillators, comprising line narrowing optics, is a function of the geometrical and dispersive features of the laser cavity.
