We demonstrated a mode-controllable fiber laser system with output power of 1.4 kW level. The system consists of a kilowatt-scale master oscillator power amplifier and an active feedback control sy…
Long range phase-sensitive optical time domain reflectometer (φ-OTDR) sensing mainly employs distributed amplification in the sensing fiber. It requires the light to be injected into both ends of …
An optoelectronic oscillator (OEO) is a microwave photonic system consisting of an amplified optoelectronic feedback loop to generate a microwave signal. To reduce the phase noise, the feedback loo…
