1512nm, DFB Laser Performance at a More Competitive Price

Product Overview:

Designed for ammonia sensing, these Eblana Photonics laser diodes are ideal for incorporating into tunable diode laser absorption spectroscopy systems for NH3 / ammonia detection. These devices offer the performance of a DFB Laser at a more affordable price. Their patented discrete mode technology is employed to deliver a cost effective solution with mode-hop free tunability and excellent SMSR. They are used extensively in high performance ammonia spectroscopy applications. Specifications include well defined tuning coefficients as well as detailed spectral data. These lasers are offered at a center wavelength of 1512nm. Their SMSR side mode suppression ratio is typically > 40 dB. They offer a typical threshold current of approximately 15 mA and their spectral width is less than 2 megahertz. Similar to DFB lasers, a key feature of these devices is their temperature tuning coefficient of 0.1 nm per degree Celsius. The user can apply a modulated drive current to tune the temperature across a spectral absorption line.
