The invention belongs to a nonlinear optical glass-ceramics material field, which relates to an environment-friendly type infrared frequency doubling chalcogenide glass ceramic, and the environment-friendly type infrared frequency doubling chalcogenide glass-ceramics is characterized in that the component of the glass-ceramics can be expressed as the chemical formula of (100 percent-x) GeS2.xAgGaS2, wherein, x stands for a molar percentage of AgGaS2, and x equals to 5 percent to 52 percent (molar), and (100 percent-x) stands for the molar percentage of GeS2. The environmental-friendly type infrared frequency doubling chalcogenide glass ceramic takes the chalcogenide glass as a fundamental glass, and the chalcogenide glass takes four high pure raw materials Ge, Ga, Ag and S as essential components and is obtained by melting in vacuum, and then the chalcogenide glass carries out nucleation under the condition of being slightly lower than the glass transition temperature and then the temperature is raised to carry out crystallization, and a large amount of environment-friendly type infrared frequency doubling chalcogenide glass ceramics with even-distributed submicron order size and excellent infrared frequency doubling performance are precipitated. The glass ceramic prepared by the invention which is stable in physicochemical performance, good in water resistance and high in glass transition temperature is non-toxic and environment friendly, and the glass ceramic which is provided with wide permeation windows and a frequency doubling performance can be applied for the technical field of an infrared wave band light variable frequency, such as frequency doubling, difference frequency, sum frequency and light parameter oscillation etc,.
