Product Overview:

1550nm DFB Laser Single Mode / Single Frequency:

Eblana's NLW series has become the industry standard in monolithic, ultra narrow linewidth laser diodes in the near infrared. Built on Eblana's Discrete Mode technology platform these lasers are the ultimate solution where the highest spectral purity must be delivered in the harshest environmental conditions.

Eblana's DFB laser is built using discrete-mode (DM) technology, these lasers are the ultimate solution where the highest spectral purity must be delivered in the harshest environmental conditions. These lasers deliver a cost-effective laser diode with mode-hop free tuneability, excellent SMSR, and ultra-narrow linewidth less than 100 kHz.

The EP1550-NLW laser diode is available in the 1547 - 1553 nm range, features an ultra-narrow linewidth making it ideal for coherent comms, metrology, and sensing applications. These devices are offered at 1550nm for tunable diode laser absorption spectroscopy specific to Methane ( CH4 ) detection.

1550nm for Telecom and LIDAR Applications

Eblana's EP1550-NLW 1550nm DM laser delivers reliable, mode-hop free, operation over a wide operating temperature range. These single longitudinal mode lasers are ideal for coherent comms and metrology applications, and for tunable diode laser absorption spectroscopy specific to CH4 detection. The ultra-narrow linewidth output improves application performance across a wide range of operating conditions, and at a very affordable price.

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.
