Enhanced Ammonia (NH3) Sensing

Eblana Photonics Ltd (Ireland) have announced the release of a Single Wavelength 1512nm Laser Diode for Ammonia detection, using Tunable Diode Laser Absorption Spectroscopy (TDLAS) systems. This laser is available as a high performance “14 pin Butterfly” component (with integrated TEC and isolator) or at a higher level of integration with a built-in low noise current driver and temperature controller in the form of Eblana’s DX1-Sensing module.

The EP1512-DM product series broadens Eblana’s existing portfolio of lasers for gas detection which already included lasers for detecting Methane (λ=1654nm), Carbon Dioxide (λ=2004nm) and Moisture (λ=1392nm & 1877nm). All of these lasers are now available in the DX1-Sensing format.

The EP1512-DM is fabricated using Eblana’s Discrete Mode (DM) single-line laser technology platform, which delivers DFB-like performance at a price point geared to high volume applications. Eblana’s strained quantum well InP design provides stable, high performance, single wavelength operation and a wide degree of current tuning for wavelength control.

Dr. Rob Lennox, Sales & Marketing Manager at Eblana, says “The 1512nm DM laser was introduced in response to an increasing demand for a cost effective laser for scalable deployment of NH₃ detection systems based on TDLAS. Eblana’s lasers provide precise wavelength control and stable performance at a compelling price point for large-scale adoption of laser based gas detection systems. This latter point is our primary focus.”
