Lk. Denisov et al., SERVICE LIFE OF DYE-IMPREGNATED POLYMER A CTIVE LASER ELEMENTS AT VARIOUS ENERGY DENSITIES AND PUMP POWERS, Kvantovaa elektronika, 24(2), 1997, pp. 119-122
The dependence of the rate of photodecomposition of the dye rhodamine
6G in polymer active elements on the average pump intensity was studie
d. The service life of such active elements pumped transversely with l
ow-intensity (less than 1 MW/cm(2)) pump pulses was also investigated.
When the average intensity was reduced below a certain value, the dye
photodecomposition rare decreased significantly and the service life
of the active elements rose strongly.
