为了研究掺钕无机惰性液体的配制、光谱和激光特性,采用实验研究的方法,在实验室制备了无机惰性液体激光增益介质Nd-POCl_3-SnO_2,测试了其抽运吸收和荧光特性:采用氙灯抽运和行波放大的方法实验研究了该液体的增益特性,并进行了初步的自由振荡出光实验.得到了性质稳定的掺钕无机惰性液体,利用该液体作为增益介质的放大器获得了1%/cm的增益系数,激光器实验则获得了中心波长为1051nm、脉宽为83.33μs的自由振荡激光输出.结果表明,掺钕无机惰性液体的配制的必要措施是干燥条件的保证,同时Lewis酸和掺钕浓度对于液体的荧光寿命也起到限制作用,该液体增益介质的光谱特性接近激光钕玻璃,单脉冲工作条件下可以得到稳定的激光输出.

For the sake of research of producing method,light spectrum and laser characteristics of Nd-doped inorganic liquid,Nd-POCl_3-SnO_2 was compound in the laboratory.The absorption and fluorescent characteristics of the liquid was tested.With flashlamp pumping and traveling wave amplification,the gain of the liquid was studied.Stable Nd-doped inorganic laser liquid was achieved,whose gain coefficient was 1%/cm at 1051nm central wavelength with 83.33μs pulse width.It is indicated that stable Nd-doped inorganic liquid can be compounded under dry condition and at proper Lewis acid and Nd concentration, its light spectrum was similar to that of Nd glass,stable laser can be output at single pulse mode.
