利用低光强曝光进行全息液晶/聚合物光栅（HPDLC）的制备，获得了内部无液晶微滴具有聚合物支撑形貌的低散射透射光栅结构. 分别研究了染料PM567，DCM，DCJTI 的放大的自发辐射（ASE）阈值及相对出射光强等性质，得到三种染料中DCJIT的ASE阈值最低，相对出射光强最高，表明DCJTI更适于制备低阈值、高转化效率激光器. 分别采用这三种染料制备基于聚合物支撑形貌光栅的分布反馈式激光器，通过改变光栅周期得到不同出射波长的激光. 其中，以DCJTI为工作物质，得到中心波长为648 nm，阈值为0.65 μJ/pulse，转化效率为1.6%，线宽为0.3 nm的高性能激光. 与国内外同类激光器相比，在阈值、转化效率、线宽三个方面均有不同程度的提高.We have made a low scattering holographic polymer dispersed liquid crystal (HPDLC) transmission grating with polymer scaffolding morphology, which was fabricated under the condition of low curing intensity and no liquid crystal droplet. We studied the amplified spontaneous emission (ASE) thresholds and relative intensities of PM567(4, 4-difluoro-1, 3, 5, 7, 8-pentamethyl-2, 6-diethyl-4-bora-3a, 4a-diaza-s-indacene), DCM (4-Dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran), and DCJTI(4-dicyanomethylene)-2-isopropyl-6-(1, 1, 7, 7-tetramethylzulolidyl-9-enyl)-4H-pyran). It is shown that the dye DCJTI has the best properties of ASE, the lowest threshold and the highest relative intensity among the three dyes. Results suggest that DCJIT is a promising material for low threshold, high slope efficiency lasers. Each dye was doped in HPDLC grating with polymer scaffolding morphology individually, and lasers with different wavelengths can be obtained by changing the period of the gratings. The excellent laser property is obtained from the DCJIT-doped laser. A spectral linewidth of 0.3 nm is observed at pump energy threshold 0.65 J/pulse and a conversion efficiency of 1.6% is achieved at the operating wavelength 635 nm. The laser performance is improved in some aspects such as threshold energy, conversion efficiency, and linewidth to some extent as compared with those reported previously.
