Abstract

The Q-switching elements are based on thiopyrylotricarbocyanine dyes introduced into polyurethane polymer matrix. We report on the spectroscopic and photochemical properties of the dye in the polyurethane matrice and durability resource characteristics of the Q-switching elements. The Q-switching efficiency of the new elements exceeded the efficiency of the elements based on the BDN dyes by 50%. The absorption cross-section of the thiopyrylotricarbocyanine dyes in polyurethane polymer is 6•10^-16 in the spectral range 1.064-1.079 mkm, relaxation time 35-55 picoseconds.
