Product Overview:

976nm, 750mW, Laser Diode with PM Fiber; 1999CVB Series FBG Stabilized Pumps

These fiber Bragg grating stabilized laser diodes from 3SP Technologies are Telcordia qualified, high reliability single mode pumps for fiber lasers. They are powered by 3SP's in-house epitaxial wafer growth technology. These laser diodes are offered in a low profile 14-pin butterfly package with a PM fiber pigtail. They operate at a recommended operating power up to 750 mW. They incorporate a TEC cooler with a 10 kOhm NTC thermistor and a back facet monitor PD. The wavelength is “locked” utilizing a fiber Bragg grating (FBG) located in the fiber pigtail. These modules from 3SP Technologies have been extensively tested and meet the rigorous requirements of Telcordia TM GR-468-Core for EDFA telecommunications pump modules. They come with a bare fiber (no connector) termination.

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.
