nanoplus sets the standard for DFB laser technology. Since more than 20 years, nanoplus has been the technology leader for ultra-precise distributed feedback lasers. They are used for high performance gas sensing applying tunable diode laser spectroscopy. nanoplus lasers operate reliably in more than 30,000 installations worldwide. Applications include power plants, gas pipelines and emission control systems as well as airborne and satellite applications. Visit our applications section for detailled descriptions of the use of nanoplus distributed feedback lasers.
Key Features:
- monomode
- continuous wave
- room temperature
- tunable
- custom wavelengths
Technology
nanoplus uses a unique and patented technology for DFB laser manufacturing. We apply a lateral metal grating along the ridge waveguide, which is independent of the material system and provides single mode emission with superb optical properties.
