The polarization extinction ratio of the output beam may exceed 1000 and was maintained for more than 1 h via feedback control of the half-wave plate rotation speed. The pointing fluctuations introduced by rotating the half-wave plate were in the order of microradians. The high-speed rotating half-wave plate provides a lossless means of combining laser beams together with stable beam pointing.}, pages = {076107-1--076107-3}, title = {Note: Lossless laser beam combiner employing a high-speed rotating half-wave plate}, volume = {88}, year = {2017} }
