PS-NLL: Narrow Linewidth laser module
The PureSpectrumTM-NLL is a narrow linewidth, low phase noise laser module available in a wide selection of center wavelength (1300- 1320 nm, 1525- 1625 nm, and others). The PS-NLL uses a high reliability DFB laser diode in conjunction with TeraXion's patented frequency noise control technology. The PS-NLL optical performances (phase noise, linewidth, and coherence length) are matching those of single frequency fiber lasers, with the added benefits inherent of semiconductor lasers (proven out reliability, lower cost, and better energy efficiency). The PS-NLL module design is optimized to facilitate the integration in various types of OEM systems, such as
- Coherent (interferometric) sensing systems
- Brillouin OTDRs
- Acoustic sensing systems
- Motion & intrusion detection systems
- Coherent communication systems
- Any system that require low phase noise or long coherence length laser
