High Power Pulse YDFA
Amonics' pulse YDFA can amplify 1 um short pulse to high optical pulse energy. By using large core specialty Ytterbium fiber, the detrimental effects such as pulse distortion due to gain transient and nonlinearities such as SBS and SRS can be highly suppressed. The applications of the YDFAs include laser welding, material processing, biomedical treatments, and free space sensing as such airborne topographic lidars.
