Apparatus and method for producing rapid and accurate laser phase shifts

A phase controller for rapid, accurate, stable phase shifting of a continuous wave (cw) laser output combines and adjusts reference paths from before and after an EOPM to obtain maximum constructive interference when the EOPM control voltage is zero. A control voltage V for maximum destructive inter...
