Product Overview:

1278nm DFB Single Mode / Single Frequency Laser, 15mW

Eblana's DFB laser is built using discrete-mode (DM) technology, delivering a cost-effective laser diode with mode-hop free tuneability, SMSR greater than 40dB, and narrow linewidths.

The model EP1278 DFB laser from Eblana Photonics is available at a range of wavelengths from 1260 - 1288 nm for a wide range of sensing applications.

1278nm for Hydrogen Flouride Sensing Applications

The 1278nm single longitudinal mode laser is designed specifically for detection of Hydrogen Flouride. The unique DM technology platform was designed to deliver unrivaled wavelength uniformity and stability for high-sensitivity gas detection applications.

Proper Handling and Operation of DFB Lasers

Diode lasers are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
