976 nm Mini-Butterfly Laser Diode Pump Module With Fbg And Pm Fiber
The Coherent CM97-1000-76PM wavelength stabilized high power single mode laser diode module has been designed as a pump source for industrial pulsed fiber pre-amplifiers as well as for erbium doped fiber amplifier (EDFA) laser applications. Processes and techniques of coupling the fiber to the laser allow very high output powers that are stable with both time and temperature. The pump module utilizes a Polarization maintaining fiber pigtail and a fiber Bragg grating design for enhanced wavelength and power stability performance. Devices achieve high kink free output powers of 1 W.

Notes:
1. Conditions unless otherwise stated:
Case temperature -20 to +75°C, Submount temperature 25°C, Monitor diode bias: -5 V, CW operation
2. At -5V bias voltage
3. The absolute maximum ratings are conditions for which the device is expected to recover fully the specified performance. Exceeding these limits may impair the device reliability. The ratings apply to each parameter in isolation; that is when all other parameter have values within the relevant characteristics. It cannot be assumed that limiting values of more than one parameter may be applied to a device at the same time.
