L波段窄线宽激光器 5kHz线宽20mW保偏输出
The Narrow Linewidth Fiber Source (NLFS) utilizes cutting edge frequency noise technology allowing it to possess low phase noise characteristics. As a result, this device has the ability to significantly reduce the optical linewidth of the DFB laser diode, while maintaining advantages of a typical semiconductor laser. The applications include: interferometer source, fiber sensors, long coherence laser system and laboratory testing.
Based on a DFB semiconductor laser, Optilab NLFS series products are constructed with 100% Telcordia-qualified components to ensure 15+ years of continuous operating life, backed by a three year limited warranty on complete system functionality. Our customer service team provides technical support for any inquires for the operation of the product.
Features:
- 5kHz laser linewidth
- Up to 40mW output
- Frequency stabilized
- Polarization Maintaining (PM) output
- Customer specify wavelength
- Front panel plus LabVIEW program monitoring and control
