Product Overview:

1854nm DFB Single Mode / Single Frequency Laser Diode, 10mW

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 EP1854-DM-TP39 laser diode, available in a range from 1845 nm - 1920 nm, is specifically designed for sensitive detection of water and water vapor ( H2O ). The TO-39 package is integrated with TEC and thermistor for precision temperature and wavelength control.

1854 nm for Sensing Water and Water Vapor ( H2O )

Eblana's 1854 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.

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.
