Based on the self-developed seed laser technology, PreciLasers can provide three types of seed lasers: external cavity semiconductor lasers, fixed external cavity semiconductor lasers, and fiber DFB lasers. According to the different doped fibers, fiber DFB lasers are divided into ytterbium-doped fiber DFB lasers, erbium-doped fiber DFB lasers, and thulium-doped fiber DFB lasers.
External cavity semiconductor laser features:
- 100mW power output
- 100kHz linewidth
- Able to achieve output from visible light to infrared band
- Never mode-hop
- Never mode-hop
Fixed external cavity semiconductor laser features:
- Never mode-hop
- Good environmental adaptability
- 10kHz line width
- MHz fast current tuning
- Low intensity noise
Fiber DFB features:
- Never mode-hop
- kHz Linewidth
- Can achieve 1012-2050nm band output
