Product Overview:

2004nm DFB Single Mode / Single Frequency Laser, 5mW

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. The EP2004 laser diode is available at center wavelengths from 1970 nm to 2051 nm.

Eblana Photonics EP2004 laser diode is specifically designed for sensitive detection of Carbon Dioxide ( CO2 ). The TO-39 package is integrated with TEC and thermistor for precision temperature and wavelength control, and is easily integrated into your application.

2004 nm for Sensing Carbon Dioxide ( CO2 )

Eblana's 2004 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 Carbon Dioxide ( CO2 ). The narrow linewidth output improves application performance across a wide range of operating conditions.

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.
