Product Overview:

High Power 976nm, 950mW, Fiber Bragg Grating Stabilized Pump Laser Diode with PM Fiber

These 950mW fiber Bragg grating stabilized 976nm laser diodes are the newest generation of ultra-high power pumps from 3SP Technologies, the industries' leading manufacturer of grating stabilized laser diodes for doped fiber pumping applications. They are utilized extensively in fiber laser pumping applications which require a single mode first stage pump source. These pumps are qualified to the stringent Telcordia testing requirements demanded for use in submarine EDFA's.

They are based on in-house wafer growth and chip development technology. The butterfly package is a low profile, epoxy-free, 14-pin module which offers > 950 milli-watts of CW output power. The wavelength is locked using an FBG which is located in the polarization maintaining (PM) fiber pigtail. These laser diodes are offered with bare fiber (no connector) for direct coupling.

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.
