Product Overview:

1512nm DFB Laser, Single Mode / Single Frequency, 10mW:

Eblana's high performance DFB laser is built using discrete-mode (DM) technology, delivering a laser diode with mode-hop free tuneability, excellent SMSR, and narrow linewidth, at a very affordable price.

1278nm for Ammonia ( NH3 ) Sensing Applications

The 1512nm single longitudinal mode laser is designed specifically for detecting Ammonia ( NH3 ). Our DM technology platform delivers unrivaled wavelength uniformity and stability which is essential for high-performance, high-sensitivity gas detection applications. The drive current can be modulated to tune the laser output across a spectral absorption line.

Available Preconfigured Driver Maximizes Cost Effectiveness

Eblana's proprietary DX-1 incorporates the butterfly laser module with an integrated current driver and TEC controller. Designed for ease of operation, it is the ideal platform for high stability gas detection or remote sensing. The driver module is compact, at 72.5 mm x 50 mm x 28 mm, to fit within your sensing system hardware and simplifies your design work considerably.

Features of the DX-1 Laser Diode Driver
    - Integrated driver and TEC controller
    - PM/SMF coupled with FC/APC
    - Built-in optical isolator
    - Powered by +5 V DC source

Proper Handling and Operation of Diode 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.
