Single Frequency Discrete-Mode (DM) technology Laser Diodes

These Single Frequency 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 Single Frequency laser diodes are produced with a simple and low cost fabrication process and have many advantages over distributed feedback and distributed Bragg reflector lasers, such as very high side mode suppression ratio, stable operation over a large temperature range, narrow linewidth and low sensitivity to optical feedback.

All of Eblana’s Single Mode lasers are of monolithic construction making them ideal for operation in environments prone to mechanical shock and vibration. Eblana has supplied lasers to a range of aerospace applications including the European Space Agency’s next generation atomic clock development program.

Eblana’s Single Frequency laser diodes are the preferred choice of the Optical Test and Measurement industry due to their extremely narrow line widths and affordability for a wide range of applications. Eblana’s flagship EP1550-NLW product has been deployed in a host of test, measurement and imaging systems.

These Single Frequency laser diodes are available in wavelengths ranging from 689 nm – 2350 nm.

Available Wavelengths:

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


Wavelengths for Gas Sensing Laser Diodes:

Eblana’s Single Mode Lasers are used extensively for high sensitivity detection of gases such as Carbon Dioxide (CO2)Methane (CH4)Ammonia (NH3) and Hydrogen Fluoride (HF). Our DM technology platform delivers unrivalled wavelength uniformity and stability which is critical for these applications.

Here are some of the most requested gases and the wavelengths needed.
