Product Overview:

1950nm DFB Single Mode / Single Frequency Laser Diode, 2mW

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 EP1950 laser, available in the range from 1908 nm - 1970 nm. The butterfly package is integrated with TEC and thermistor for precision temperature and wavelength control, and includes an integrated optical isolator.

1742 nm for Sensing Hydrogen Chloride ( HCl )

Eblana's 1950nm DM Laser delivers reliable, mode-hop free, operation over a wide operating temperature range. These single longitudinal mode lasers are designed for seeding Thulium doped fiber amplifiers and lasers, as well as various sensing applications. The narrow linewidth single mode operation of these laser diodes is ideal for maximum seeding efficiency .

Available Preconfigured Driver Maximizes Cost Effectiveness

Eblana's proprietary DX-1 incorporates the butterfly laser module with an integrated current driver and TEC controller. Because it is compact and designed for ease of operation, it is the ideal platform for a wide range of application requirements. The driver module is compact, at 72.5 mm x 50 mm x 28 mm, to fit within your 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.
