Investigation of polarization characteristics of radiation from laser with dye-activated polymer elements

The polarization characteristics of a laser with active elements made of oxazine-17 activated polymethylmethacrylate are investigated and compared with the analogous parameters of a laser employing solutions of oxazine-17 in different solvents. The influence of the activator on the properties of the polymer elements activated by complex organic compounds is assessed. The lasing efficiency and degree of polarization during transverse and quasi-longitudinal excitation at the second harmonic (532 nm) of a frequency monopulse YAG laser are determined as a function of the aximuth of the polarization, the power of the exciting light, and the parameters of the cavity of the dye laser. The properties of polymer lasers are found to depend more upon the polarization of the exciting light than dye lasers, which is important when polymer is found to be the fundamental factor determining the efficiency in polarization of the laser.
