【Abstract】 Two kinds of tunable solid state dye laser cavities based on holographic grating were established for pyrromethene 567 doped sample made by stepwise synthesis technique through a sol gel process. With the cavity of output from zero order diffractive beam, tunable range of about 70 nm from 543～610 nm had been achieved, and the highest slope efficiency of 17% was obtained at 583 nm wavelength. While using the cavity of output from a coupling mirror, tunable range of over 30 nm from 553～585 nm was obtained, and the slope efficiency was 9.7% at 574 nm wavelength. Furthermore the parameters of laser tunable range, threshold, slope efficiency, and linewidth of the two different cavities are deeply analyzed.更多还原
