Overview of EP1521-DM-B: 1521nm DM Laser Diode for Acetylene Gas Sensing

Eblana Photonics, experts in tunable diode lasers for gas sensing applications, offer the EP1521-DM-B laser for Acetylene detection which is continuously tunable from 1490 nm to 1530 nm.   This laser diode is ideal for tunable diode laser absorption spectroscopy (TDLAS), providing a low maintenance solution for real-time trace gas sensing (ppm or ppb levels) in harsh environments.  The EP1521-DM-B diode laser takes advantage of Eblana`s proprietary discrete-mode (DM) technology which produces a tunable single frequency output with excellent SMSR, similar to traditional DFB lasers without the mode hops inherent to most DFBs.
