Common types of laser crystals
I. Neodymium-doped yttrium aluminum garnet (Nd:YAG)
Nd:YAG laser crystals are widely popular due to their high efficiency, low threshold, and long lifespan. Their emitted 1.06-micrometer laser has in-depth applications in numerous fields, including medicine, manufacturing, and communications.
II. Neodymium-doped yttrium vanadate (Nd:YVO4)
Compared to Nd:YAG, Nd:YVO4 possesses a higher absorption cross-section and thermal conductivity, enabling higher optical output power and shorter laser pulses. This crystal excels in miniature lasers, laser displays, and optical communications.
III. Neodymium-doped glass (Nd:glass)
Nd:glass laser crystals are renowned for their high optical quality, long lifespan, and high gain coefficient. Nd:glass plays an indispensable role in high-power lasers and radar systems.
IV. Erbium-doped yttrium aluminum garnet (Er:YAG)
Er:YAG is a novel laser crystal that emits a 2.94-micrometer laser. It shows great application potential in medical aesthetics and dental treatments.
In summary, with the continuous advancement of laser technology, different types of laser crystal luminescent materials are constantly expanding their application range, laying a solid foundation for future technological development.
