Description
Technical Field
The invention belongs to the technical field of laser glass, and particularly relates to bismuth boron aluminum tunable laser glass and a preparation method thereof.
Background
Among the mid-infrared lasers, the mid-infrared laser with the wave band of 2 mu m has wide application prospect in the aspects of long-distance laser communication, laser remote sensing, environmental pollution detection and analysis, laser radar with safety to human eyes, medical surgery and the like; besides, 2.0 μm wave band laser can also be used as an ideal pumping source of mid-infrared laser (3-5 μm). Therefore, a 2.0 μm band fiber laser has become one of the research hotspots in recent years. The research of rare earth doped laser glass fiber as the core gain medium of fiber laser has been a key problem in the laser glass field. Tm is 3+ The active ion is considered to be an ideal active ion for obtaining 2 mu m laser because of the characteristics of strong absorption peak in 800nm waveband, high quantum efficiency (the theoretical quantum efficiency can reach 200%), wide output wavelength (1700-2100 nm) and the like. In 1988, hanna D.C. of Ministron university of south America in England, the 1.88-1.96 mu m laser oscillation is observed in a thulium-doped quartz single-mode optical fiber for the first time, and in 2009, wang et al reports a thulium-doped silicate glass optical fiber, and laser output with the central wavelength of 1980nm, the pulse energy of 0.76nJ and the slope efficiency of 68.3 percent is obtained. Kuan et al reported a passively Q-switched thulium ion doped tellurate glass fiber laser with an average energy of 84mW in 2015.
Up to now, thulium ion doped 2 μm mid-infrared luminescence has been realized in many different types of glass matrices, mainly classified into two broad categories, including oxide (quartz, silicate, phosphate, germanate, tellurate, etc.) and non-oxide (fluoride and chalcogenide) glasses. Non-oxide glasses, despite their lower phonon energy, have been severely limited in their application due to poor chemical stability, mechanical strength, and lower laser damage threshold. Among oxide glasses, quartz glass, silicate glass, phosphate glass, etc. have limited their application in infrared luminescence in the 2 μm band due to their high phonon energy. However, heavy metal oxide glasses (including tellurate, germanate, and bismuth glasses) have been widely studied in the field of laser glass and fiber lasers in recent years due to their advantages such as low phonon energy, high solubility of rare earth ions, and wide infrared transmission range. Among heavy metal oxide glasses, tellurate glass has poor machining performance, and germanate glass has high hydroxyl content and poor devitrification resistance. Compared with bismuthate glass, the bismuthate glass has lower phonon energy, better mechanical processing performance and crystallization resistance; therefore, the research of thulium ion doped bismuthate glass has stronger theoretical and practical significance for the development of the field of mid-infrared laser with the wave band of 2 mu m.
The applicant finds that the rare earth ion solubility of the bismuth germanium or bismuth silicon laser glass system widely adopted at present is difficult to meet the demand based on the urgent demand of the fields of medical surgery and the like for a fiber laser with higher power and a wave band of 2 mu m. Therefore, a novel heavy metal laser glass system with high rare earth ion solubility and excellent performance is explored, and the method has important significance for realizing high-gain active glass optical fibers and optical fiber lasers.
