Product Overview:

1877nm DFB Single Mode / Single Frequency Laser Diode, 3mW

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

Eblana Photonics EP1877 laser diode, available in a range from 1845 nm - 1920 nm, is specifically designed for sensitive detection of water and water vapor ( H2O ). The butterfly package is integrated with TEC and thermistor for precision temperature and wavelength control.

1877 nm for Sensing Water and Water Vapor ( H2O )

Eblana's 1877 nm DM Laser delivers reliable, mode-hop free, operation over a wide wavelength tuning range. These single longitudinal mode lasers are designed specifically for gas sensing applications targeting water and water vapor sensing applications ( H2O ). The narrow linewidth output improves application performance across a wide range of operating conditions.

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.
