Pulsed 1064 nm Ultra Broad Bandwidth Fbg High Power Mini-Butterfly Laser Diode Module
The Coherent CM97A1064BFBG next generation wavelength stabilized high power single mode laser module has been designed as a light source for pulsed fiber laser applications. Processes and techniques of coupling the fiber to the laser allow high kink free peak output powers that are very stable with both time and temperature. An ultra broad bandwidth grating enables a controlled broad spectrum that helps to suppress SBS generation in pulsed fiber lasers.

Notes:
1. Conditions unless otherwise stated:
Case temperature -20 to +75°C, Submount temperature 25°C, Monitor diode bias: -5 V, CW operation
2. <500 ns / 500kHz
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.
