974nm 600mW Pump Laser Diode
Product Description
Product Detail
1. Summary of 974nm 600mW Pump Laser Diode
The 974nm 600mW Pump Laser Diode are designed as pump sources for erbium doped fiber amplifier (EDFA) applications. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. The grating is located in the pigtail to stabilize the wavelength. Devices are available with kink free output powers to 600mW. The 976nm 600mW PM FBG Stabilized pigtailed butterfly Pump laser diode series pump module utilises a Fiber Bragg Grating design for enhanced wavelength and power stability performance. This product has been designed to ensure superior wavelength locking over drive current, temperature and optical feedback changes.
