Abstract

The caloric energy accumulated during the laser excitation process of dye doped polymeric materials as a function of the laser pump rate (f) was analyzed by using Photothermal Deflection Spectroscopy (PTDS). Results show that the thermal effects should be very important for pump rates larger than 1 Hz and that the possibility of chemical degradation of the laser material increase with the enlargement of the sample temperature under the pump process. Experimental results have been theoretically simulated by using an optical dense material model of PTDS.
