Effects of the polyurethane matrix polarity on spectral, nonlinear-optic, and switching properties of thiopyrilo-4-triocarbocyanine phototropic dye are studied. The experimental results of the passive Q-switching for a neodymium laser by Q-switches based on aliphatic polyurethane of high dielectric permittivity are presented. The positive influence of the polymer matrix polarity on a high-efficient generation of powerful single pulses is shown.
