Applications:

1. Used as an additive for metal halide lamps. Metal halide lamps are gas discharge lamps developed on the basis of high-pressure mercury lamps. They are characterized by filling the bulb with various rare earth halides. At present, rare earth iodides are mainly used, which emit different spectral 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 region, 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 a 2μm laser, and the absorption rate of the human tissue to the 2μm laser is high, which is almost 3 orders of magnitude higher than that of Hd:YAG. Therefore, when the Ho:YAG laser is used for medical surgery, it can not only improve the efficiency and precision of the surgery, but also reduce the thermal damage area to a smaller size.

The free beam produced by the holmium crystals removes fat without generating excessive heat, thereby reducing thermal damage to healthy tissue. The use of holmium lasers to treat glaucoma has been reported to reduce the pain of surgery for patients. The level of 2μm laser crystals in my country has reached the international level, and we should vigorously develop and produce such laser crystals.

4. In the magnetostrictive alloy Terfenol-D, a small amount of holmium can also be added to reduce the external field required for the saturation magnetization of the alloy.

5. In addition, holmium-doped fiber can be used to make fiber lasers, fiber amplifiers, fiber sensors and other optical communication devices, which will play a more important role in today's rapid fiber communication.
