Product Overview:

1555nm DFB Laser, Single-Mode Fiber-Coupled

These fiber-coupled lasers come in a standard 14-pin butterfly package with SMF28 single-mode fiber. Common applications include spectroscopy, metrology, sensing, telecommunications, and use in atomic physics research. At a wavelength of 1555nm, up to 40mW of output power is available in pulsed mode, and 20mW in CW operation. An integrated TE cooler, thermistor, and monitor photodiode are also included. High stability and wavelength tuneability are also notable features of these lasers.

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.
