Nanosecond Fiber Laser


Amonics' nanosecond fiber lasers are with high pulse energy and excellent pulse energy stability. We offer nanosecond fibers with direct modulation diode seed lasers and narrow linewidth seed lasers with external modulation.By using our high power pulse amplifier, the laser with direction modulation can have higher than mJ output energy.By using our proprietary SBS suppression technique, our narrow linewidth nanosecond pulse laser can deliver over 180 uJ pulse energy.The applications of the nanosecond laser include laser marking, laser welding, material processing, and free spacing sensing.
