| Abstract: | Coherent beam combination(CBC) is an effective way to generate high-power and high-radiance laser beams.A kind of adaptive fiber optics collimator(AFOC) was designed which could realize fast and precise corrections of wavefront tip/tilt phase errors in CBC.Compared with the traditional fast steering mirror,this AFOC promises larger beam-tip/tilt range and higher resonance frequency.In the AFOC,four bimorph actuators were employed to control the deviation of the fiber tip and the output beam was collimated b... |
