Product Description


Holmium Ho is a rare earth element. The main uses of holmium are: (1) As an additive to metal halide lamps, metal halide lamps are gas discharge lamps, which are developed on the basis of high-pressure mercury lamps, and are characterized by filling the bulb with various rare earth halides. The main use is rare earth iodide, which emits different spectrum light colors during gas discharge. The working substance used in the holmium lamp is holmium iodide, which can obtain a higher concentration of metal atoms in the arc zone, thereby greatly improving the radiation efficiency. (2) Holmium can be used as an additive for yttrium iron or yttrium aluminum garnet; (3) The holmium-doped yttrium aluminum garnet (Ho:YAG) can emit 2μm laser, and the human body tissue has a high absorption rate of 2μm laser, which is almost 3 orders of magnitude higher than Hd:YAG. Therefore, when the Ho:YAG laser is used for medical surgery, not only can the efficiency and accuracy of the operation be improved, but also the thermal damage area can be reduced to a smaller size. The free light beam produced by the holmium crystal can eliminate fat without generating excessive heat, thereby reducing thermal damage to healthy tissues. According to reports, the use of holmium laser to treat glaucoma in the United States can reduce the pain of surgery for patients. The level of China’s 2μm laser crystal has reached the international level, and it is necessary to vigorously develop and produce this laser crystal.
