Narrow Linewidth Laser Diodes for Gas Sensing

DM Laser Diodes

These Narrow Linewidth Laser Diodes feature Eblana’s Discreet-Mode (DM) technology which allows for excellent SMSR and narrow linewidth (<2MHz),  making them a cost effective solution for Gas Sensing and scientific needs. Since laser-based gas sensing requires excellent tuning characteristics, Eblana’s DM lasers are the ideal choice because they feature mode-hop-free tuning over a minimum of 2nm. See our new Lasers 101 page for in depth information on Laser Diodes.

These lasers are available in wavelengths ranging from 760nm – 2300nm.

Available Wavelengths:

  • 758-764nm
  • 778-784nm
  • 1260-1288nm
  • 1378-1400nm
  • 1490-1530nm
  • 1540-1560nm
  • 1560-1573nm
  • 1640-1670nm
  • 1735-1770nm
  • 1845-1920nm
  • 1950-2150nm
