英文摘要: We present a strip extracting algorithm (SEA) for detecting and locking the phase noise of fiber amplifiers. Based on the algorithm, the phase noise of a 10 W Yb fiber amplifier is obtained and locked with an active segment mirror (ASM) and a high-speed CCD camera. Experimental results indicate that within the first 3 seconds after turn-on transients occur the amplitude of phase noise exceeds 20 waves, whereas in thermal steady-state operation it amounts to only several waves for the same time span. After phase locking, the Peak-to-Valley (PV) value of phase noise is close to similar to 1/10 lambda (lambda=1064 nm), and the control bandwidth of the system is similar to 25 Hz.
