1278nm DFB Single Mode / Single Frequency Laser, 10mW

Product Overview:

1278nm DFB Single Mode / Single Frequency Laser, 10mW

Eblana's DFB laser is built using discrete-mode (DM) technology, delivering a cost-effective laser with mode-hop free tuneability, excellent SMSR, and narrow linewidth.

The model EP1278 laser from Eblana Photonics is available at 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. Our DM technology platform delivers unrivaled wavelength uniformity and stability which is critical for high-sensitivity gas detection applications.

Available Preconfigured Driver Maximizes Cost Effectiveness

Eblana's proprietary DX-1 incorporates the butterfly laser module with an integrated current driver and TEC controller.

Important Notes on Operating DFB Lasers:

Electrical Operation: Operating a laser above the maximum ratings shown on the data sheet even for very short periods of time can damage the laser diode or reduce its lifetime. They should be electrically biased with a "laser diode driver" class current supply with low electrical noise and protection against voltage and current surges. Laser diodes are very sensitive to electrostatic discharge (ESD). Proper ESD precautions must be taken.

Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diode‘s package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
