The nc-Si/SiNx superlattice films were prepared by radio-frequency(RF) magnetron sputtering method and thermal annealing techinque.The passively Q-switched operation of a LD pumped Nd∶YVO4 1 342 nm laser was achieved by inserting the nc-Si/SiNx film as a saturable absorber into the plane-concave resonator.The pulse train with average pulse duration of 20 ns and pulse repetition rate of 33.3 kHz was obtained.The passively Q-switching mechanism of 1 342 nm laser was analyzed and it was mainly… CONTINUE READING
