Laser Crystals -> Nd:YAG Crystal |
|
| |
|
|
|
|
|
| |
Nd:YAG Crystal (Neodimium Doped Yttrium Aluminum Garnet) |
|
|
|
|
| |
Advantages |
|
| |
Since invented in the sixties of the last century, Nd:YAG has been and continue to be the most widely used laser crystal for solid-state crystal material. Its laser parameters 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-frequency-doubled continuous wave, high-energy Q-switched, and so forth. Compared with others laser crystals, its fluorescence lifetime is twice more than Nd:YVO4, and thermal conductivity is also better. |
|
| |
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 |
| |
|
Nd:YAG can be Q-switched with Cr4+YAG directly |
| |
|
Due to the cubic symmetry and high quality, Nd:YAG is easy to operate with TEM00 mode |
