Nano-second Pulse EDFA


Amonics' Pulse EDFA is designed for amplifying optical short pulse to high pulse energy level. Amonics’ engineers have a lot of knowledge in designing pulse optical amplifier, especially handling the nonlinearity in optical fiber due to high pulse peak power of the optical short pulse. We can design custom pulsed EDFA for different applications, such as fiber optic sensing and free space optical sensing.Our pulse EDFA has been widely used in industrial fiber laser based Lidar systems for wind velocity detection.
