For the sake of research of producing method, light spectrum and laser characteristics of Nd-doped inorganic liquid, Nd-POCl3-SnO2 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.
