Abstract

A polymeric multilayered mirror doped with a saturable dye worked as a passive Q-switch of a laser-diode-pumped Nd3+:YVO4 microchip laser. The multilayered mirror consisted of alternately spin-coated layers of polyvinylcarbazole (PVK) and cellulose acetate on a glass substrate. A dye of bis-(dimethylaminodithiobenzil)-nickel was doped in one of the layers of PVK, providing the repetitively Q-switched pulses. The pulse width and repetition rate were 4ns and 68kHz, respectively, for a laser-cavity length of 5mm, and the average and the peak power were 40mW and 156W, respectively, for the highest pump power of 435mW. The dependence of the Q-switched characteristics on the pump power and on the concentration of the doped dye is described.
