  Tuneable Laser Absorption Spectroscopy (TDLAS) technology is a very sensitive, accurate, reliable and interference resistant gas detection method.Although the technique was well developed over last 20 years, its deployment still limited to a small quantity of in lab, critical and high value applications.The major bottleneck for mass deployment is the availability and cost of the laser, a key part in the technique.To solve this issue, we report an innovative single mode laser technology, our DM laser technology.This technology has not only dramatically improved the yield and cost but also enabled quick and cost effective implementation of new wavelengths required by specific gases.
