“…A 2 cm cell containing a solution of iodine in carbon tetrachloride (as used for the reported observation of stimulated thermal Rayleigh scattering [25]) when placed in the ruby laser cavity did show some pulse sharpening (width approximately 150 nsec). However, solutions having an absorption coefficient greater than 0.1 cm -1 were required for observing the stimulated Rayleigh effect [24,25], whereas pulse sharpening behaviour occurs in liquids with an absorption as low as 0.01 cm -1 (using the neodymium laser).…”

Laser Q-switching by organic solvents

The role of the solvent in the passive Q-switching of lasers by solutions of organic dyes has been examined in detail. It was found that several pure organic solvents could themselves partially Q-switch the laser, in the absence of the dye. This behaviour was observed for both ruby and neodymium : glass lasers. Pulse-widths as short as 20 nsec were occasionally recorded. Peak powers up to 2 MW have been observed using 1-chloronaphthalene to switch a ruby laser. It is proposed that Q-switching arises from an enhancement of reflectivity of the liquid, during the evolution of the laser pulse, through the formation of a periodic refractive index modulation in the liquid by the action of standing waves.

“…Stimulated thermal Rayleigh scattering [24] may provide an alternative explanation for pulsesharpening behaviour. In this process the backscattered intensity of laser light incident on an absorbing liquid is enhanced through interaction with large, coherent density fluctuations produced by local heating.…”

A linear theory of laser heating is used to describe the coupling of optical waves to thermally induced acoustic and entropy perturbations of the medium. The analysis differs from those of previous authors in its treatment of entropy, dissipative effects, and active compensation of thermally induced laser-beamaberrations. An intuitively simple equation for the medium perturbation is derived, within the hydrodynamic approximation. The dimensionless parameters that characterize the diverse scattering regimes are discussed. The boundary-value problem is solved for specific cases of interest. Comparison with a nonlinear simulation verifies the linearized result in such cases.PACS number(s): 42.68. Mj, 42.20.Ji, 42.65.Es, 62.60.+v
