Abstract
The solid dye samples used in our experiment is made by a stepwise synthesis technique through a sol gel process.Laser dye doped in the sample is pyrromethene 567.Longitudinally pumped tunable solid state dye lasers with intra cavity grating are established with Q-switched frequency doubled Nd:YAG laser pumping source.The slope efficiency of 9.7% and tunable range over 30nm(from 553nm～585nm) has been achieved.The pulse width is 4ns and the spectrum width is 0.014nm at 574nm wavelength.The laser output broad band of 7nm(FWHM) and 69% slope efficiency are also obtained in the experiment.With 0.1J/cm2 pump fluency and 2Hz repetition rate,the output energy decreases to 50% of initial value after 38000 shots.
