Product Overview:

1692nm, 5mW DFB Laser, Single Mode / Single Frequency

Eblana's DFB laser is built using discrete-mode (DM) technology, delivering a mode-hop free tuneable laser with excellent SMSR, narrow linewidth, and at a cost-effective price. Eblana Photonics EP1692 laser diode series is available at a range of wavelengths from 1680 nm - 1730 nm. The butterfly package is integrated with TEC and thermistor for precision temperature and wavelength control.

1692 nm for Sensing Hydrocarbons

Eblana's 1692nm DM Laser delivers reliable, mode-hop free, operation over a wide operating temperature range. These single longitudinal mode lasers are designed specifically for sensing applications across the hydrocarbon absorption lines around 1690nm. The narrow linewidth single mode operation of these laser diodes is ideal for a wide range of applications and environments.

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.
