“…With the exception of Ref. 59, all studies carried out to measure the component ^} 22l (co;co,co,-co) have used light pulses longer than 20 ns. In this case, with a beam transverse dimension on the order of 100 /xm, birefringence due to electrostriction may be manifested in a condensed medium 94 and may lead to a depolarization of the light which is difficult to control.…”

Research on the nonlinear refractive indices of solid dielectric active media is reviewed. The review is restricted to media for which the nonlinear refractive index is fast, i.e., has a relaxation time r< 10~9 s. The nature of the nonlinear refractive index, its relaxation time, and its dispersion are discussed. Measurements of the parameters of the nonlinear refractive index of more than 160 laser and optical glasses and crystals are collected.

“…This considerable complication of the system is avoided in one-resonator lasers with a polarisation modulator operating on the basis of the optical Kerr effect, involving self-precession of elliptically polarised radiation propagating in a nonlinear medium [12][13][14][15][16][17]. However, traditional laser media exhibit a relatively weak optical Kerr effect, and the selection of a medium suitable for a modulator is limited by the slowness of the nonlinear response of strongly nonlinear media [15].…”

A fluctuation model is used to show that effective self-mode-locking can be achieved in cw solid-state lasers with nonlinear birefringent polarisation modulators of two types. The discriminating action of modulators is based on the rotation and distortion of the polarisation ellipse, which depends on the intensity of the radiation propagating in the birefringent medium and is related to self-phase-modulation of two polarisation components. The linear phase shift of these components and the angular orientations of the modulator parts are determined to ensure that the modulator acts as a discriminator. An analysis is made of the regions of efficient self-mode-locking of cw lasers with nonlinear birefringent modulators as a function of the laser parameters.
