Paper Abstract

Polymer filled porous glass impregnates with dye molecules is used as an active medium. The most important feature of this medium is that its thermo-optical and mechanical parameters are determined by a matrix of silica which thermo-optical constants are better by two orders of magnitude then those of polymers. The investigation of generation characteristics of solid state dye laser on basis of Rhodamine 6G has shown the feasibility of its application in pulse coherent pumping laser systems. The generation thresholds are practically the same for solid state and ethanol solution. The yield of conversion of pumping energy into generation energy for solid state active element is up to 50%. The advantages of solid state active element based on polymer filled porous glass matrix realize at high temperature operation mode, for instance at frequency mode. The step refraction index temperature dependence for polymers results in increase of optical with increase of pumping energy. In the reported medium this effect does not occur nonuniformity up to pumping energy values exceeding the generation threshold by 40-50 times. Polymer based active media are destructed at the exposition of 50 ns pulses with energy of 1 J/cm2 while porous glass + polymer + Rhodamine 6G composition is not destructed at the exposition of energy up to 7-10 J/cm2. The introduced solid state dye laser is intended to be used in on-board systems, including vacuum under low temperature, where the application of flow systems operation is problematic. It should be emphasized, that using the synthesized compositions, the generation mode with microsecond pulse pumping becomes available. It opens the possibility for application of flashlamp for pumping.
