QP-NLS series of narrow linewidth laser light source uses high-performance narrow linewidth DFB laser、unique design of the ATC and APC circuit. And isolation control ensures very high power and wavelength stability, being widely used in laser radar, seed light source, long-distance coherent optical fiber communication system, optical fiber sensing system, and so on.
Features:
- ITU wavelength is optional
- High output power is available
- The narrowest linewidth is up to 5KHz
- Built-in optical isolator
- A variety of operation is optional
- Module package or desktop package
Applications:
- Laser radar
- Seed light source
- Long-distance coherent optical fiber communication system
- Optical sensing system
