The energy and spectral--temporal characteristics of stimulated emission of rhodamine 6G in different solvents under asymmetric lamp pumping is investigated experimentally as a function of the misalignment angle of the cavity. It is shown that optical inhomogeneity arising in solution under the action of pump lamp radiation has substantial effect on these lasing parameters. Estimates are made on the value of losses due to cavity thermooptical distortions, and also on the pumping duration in which these losses become insignificant. It is shown that specific angular detuning of the cavity allows us to raise lasing energy of lasers with asymmetric lamp excitation and control and nature of temporal evolution of the lasing spectrum.
