20W 1064nm DFB Fiber Butterfly Laser Diode
FBG Stabilized Lasers are compact laser diodes designed for use as pump lasers. 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. Additionally, 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.
