600mW 976nm FBG Pump Laser Diode
Product Description
FBG Stabilized Lasers are compact laser diodes designed for use as pump lasers. The butterfly packages contain an integrated thermoelectric cooler (TEC) and thermistor. The region of the fiber marked by a pair of black bands contains a grating etched into the fiber, which acts as a Bragg reflector to provide feedback to the laser. The FBG-stabilized design produces an output that is spectrally broadened by satellite modes. A FBG-stabilized laser is not a single longitudinal mode laser; while it is stabilized in terms of frequency, the gain curve will contain many different modes.
Note
these Bragg gratings are relatively insensitive to temperature (<0.02 nm/°C). It should be noted that for the SM-pigtailed laser, stress-induced birefingence on the fiber may change the output spectrum of the laser diode. Due to the properties of the fiber, the PM-pigtailed lasers will not be affected.
Feature
The 976 nm FBG lasers produce a stable output of ≥300 mW with a single mode fiber pigtail or between 500 and 900 mW with a polarization-maintaining fiber pigtail. With a spectral bandwidth of <1 nm, they are well suited for core pumping of Erbium-doped fibers, such as in Erbium-doped fiber amplifiers, mode-locked oscillators, and CW lasers.
