| In addition to high coherence, what are the advantages of HeNe lasers? |
* Answer
| 1 easy to achieve single mode operation, and the line width is very narrow, can be as low as 1 kHz, which is more expensive for the interference type sensor;
2 high radiation density, high coupling efficiency with single mode fiber, for example, 1 mm diameterThe circular area 氦氖 laser produces a typical output power of 1 mW with a divergence angle of approximately 1 mrad. |
