Product Overview:

These 976nm pump laser diode from II-VI Laser Enterprise were designed for applications such as low noise EDFA's, dense wavelength division multiplexing (DWDM) EDFA's and CATV pumping applications. They deliver up to 600mW of kink free output power from single mode fiber. These devices These lasers are designed as pump sources for erbium doped fiber amplifier (EDFA) applications. These devices utilize a fiber Bragg grating design for enhanced wavelength and power stability performance. These products have been designed to ensure superior wavelength locking over drive current temperature and optical feedback changes. They are field proven diode lasers and come with integrated TEC cooler and thermistor.
