Abstract

The invention relates to 3 mu m luminous rare earth ion doped fluorophosphates laser glass and a preparation method thereof. The glass comprises the following components by molar percent: 15-20% of Al(PO3)3, 13-17% of MgF2, 5-25% of CaF2, 5-25% of SrF2, 17-22% of BaF2, 18-22% of NaF and 3-5% of RF3 (R can be rare-earth elements such as Er, Pr, Tm, Ho, or Nd). The glass is prepared by using a platinum crucible and a silicon carbide rod electric furnace fusion method. The glass in the invention is transparent, has no crystallization, has high infrared transmissivity at the vicinity of 3 mu m wave band, good physical and chemical properties and stability parameter delta T of more than or equal to 150 DEG C and can obtain strong 3 mu m fluorescence under the pumping of a laser diode with a wavelength of 980 nm, and the method is suitable for preparation and application of 3 mu m luminous rare earth ion doped special glass and optical fiber materials.

Description

technical field [0001] The invention relates to a fluorophosphate glass co-doped with various rare earth ions capable of realizing 3 μm light emission and a preparation method thereof. Background technique [0002] In recent years, rare earth-doped solid-state lasers with 3 μm output have attracted people's attention because of their wide application. Since the absorption peak of 3μm laser is very close to that of water, and more than 70% of biological tissue is water, the laser near 3μm is called the gold laser of dermatology, surgery, and dentistry; Sensation, air pollution control (in the environment 10 -9 Level content of formaldehyde, nitric oxide, nitrogen dioxide, hydrogen sulfide, arsenic and other harmful gases) and other aspects; moreover, the 3μm band laser is located in the two transmission windows of the atmosphere (1-3μm, 3-5μm, 8-14μm), covering many important molecular characteristic lines, therefore, it is very important in remote sensing, ranging, environ...
