Product Overview:

1877nm DFB Single Mode / Single Frequency Laser Diode, 6mW

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 EP1877-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, and is easily integrated into your application.

1877 nm for Sensing Water and Water Vapor ( H2O )

Eblana's 1877nm 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.

Important Notes on Operating Laser Diodes:

Electrical Operation: Operating a laser diode above the maximum ratings shown on the data sheet even for very short periods of time can damage the laser diode or reduce its lifetime. They should be electrically biased with a "laser diode driver" class current supply with low electrical noise and protection against voltage and current surges. Laser diodes are very sensitive to electrostatic discharge (ESD). Proper ESD precautions must be taken.

Mounting and Temperature Control: In order to maintain the lifetime of a laser diode, proper heat management is essential. Due to the design of the laser diode, heat is typically dissipated only through the base plate of the diode‘s package. A proper heat conducting interconnection between the diodes base plate and the heat sink must be maintained. Some devices require the use of a thermo-electric temperature controller (TEC controller) to remove the heat from the laser and stabilize the temperature.
