Good Thermal Conductivity And Thermal Shock Characteristics Nd:YAG Laser Crystals For High Power Lase
Products Description:
Neodymium-doped Yttrium-Aluminum Garnet (Nd:YAG) crystal is the best of the rare earth garnet materials that are characterized by four-level system which permits low threshold operation both in pulsed and CW mode. It is the most mature and widely used solid-state laser material adopted by R&D, medical, industrial and military customers. Its properties are a good compromise between the strengths and weaknesses of its competition. Nd:YAG crystals are used in all types of solid-state lasers systems, e.g. frequency-doubled continuous wave laser, high-energy Q-switched pulse laser, etc. Compared with other laser crystals, its fluorescence lifetime is twice that of Nd:YVO4, and thermal conductivity is also better.
APPLICATION:
- Nd:YAG is widely used solid-state laser material adopted by R&D, medical, industrial and military customers. For example, it can operates in the following applications.
- Nd:YAG can produce blue laser with the frequency-doubling of 946nm
- Nd:YAG can be operated in a very high power laser up to kw level at 1064nm
- Nd:YAG can be Q-switched with Cr4+YAG directly
- Nd:YAG can be used for high power green laser for SHG@1064nm
