Product Overview:

1653.7nm DFB Laser, 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 EP1654-DM-TP39 laser diode, available in a range from 1640 - 1670nm, is specifically designed for sensitive detection of Methane ( CH4 ). The TO-39 package is integrated with TEC and thermistor for precision temperature and wavelength control.

1654 nm for Sensing Methane ( CH4 )

Eblana's 1654 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 Methane ( CH4 ). The narrow linewidth output improves application performance across a wide range of operating conditions. The available standard wavelengths Include 1651 nm & 1653.7 nm; please inquire for details.

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.
