Hydrogen Chloride Detection through Ultra-Sensitive TDLAS Techniques

Eblana Photonics Ltd. (Ireland) have announced the release of a Single Wavelength 1742nm Laser Diode for Hydrogen Chloride (HCl) detection, using Tunable Diode Laser Absorption Spectroscopy (TDLAS) systems. This laser is available as a high performance “14 pin Butterfly” or “TO39” 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, for OEMs. 

Dr. Rob Lennox, Sales & Marketing Manager at Eblana, comments: “The addition of HCl at 1742nm to Eblana's range of gas sensing diodes represents an important turning point for gas detection OEMs. Until now, TDLAS OEMs have had a limited choice of laser diode suppliers at this wavelength and have been faced with high costs and long lead times. For many, this has been a barrier to entry into this otherwise attractive market. Eblana now provide spectrally pure, highly consistent DFB laser diodes at the most competitive prices in the industry, and at typically 4 week lead times. This can only be a good thing for the laser based sensing market and something of which we are very proud."

The EP1742-DM is fabricated using Eblana’s Discrete Mode (DM) single-mode 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 across Eblana’s existing portfolio of lasers for gas detection. This range already includes lasers for sensing Methane (λ=1654nm), Ammonia (λ=1512nm), Carbon Dioxide (λ=2004nm) and Moisture (λ=1392nm & 1877nm).
