PULSED 1064 nm HIGH POWER MINI-BUTTERFLY LASER DIODE MODULE
The Coherent CM 97A1064 next generation high power single mode laser module has been designed as a light source for pulsed fiber lasers and CW applications that require 1064nm single mode light. Processes and techniques of coupling the fiber to the laser allow high output powers that are very stable with both time and temperature. Devices achieve high kink free output powers of 1.5 W pulse peak.
Applications

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.
