摘要 Efficient and stable laser dyes pyrromethene-BF2 complexes were successfully incorporated into organically modified silicate(Ormosil)matrices via sol-gel process.Laser oscillation were easily observed in all hand-polished dye-doped Ormosils pumped by frequency-doubled radiation from a laser-diode pumped Q-switched Nd:YAG laser.A slope efficiency of 57% has been obtained from one of the dyes in Ormosil,the cavity was continuously tunable over 50nm,from 550 to 600nm.The laser output energy has only 10% reduction after 3.0×10^(4) pulses at a pump repetition rate of 30Hz and a pump intensity of 1 J/cm^(2).An efficient,all-solid-state,compact,long-lifetime,and tunable dye laser has been demonstrated.
