abstract = "In this paper, we present 2-dimensional (2D) large capacity time-division multiplexing (TDM) laser beam combining technique by potassium tantalate niobate (KTN) electro-optic (EO) beam deflectors. The use of the 2D TDM approach in laser beam combining brings the following key advantages: (1) a large multiplexing capacity compared to 1-dimensional combining, (2) high spatial and spectral beam quality (the combined laser beam has the same spatial and spectral beam profile as the initial individual laser beams), and (3) independency of the phase fluctuation of individual laser beams due to the nature of incoherent laser beam combining. To demonstrate an implementation of 2D beam combining, we recorded the beam after passing KTN crystals with a CCD camera. Our result shows beam combining with a high beam quality, leading to the higher capacity of the TDM technique, which can play a crucial role in applications such as high-energy lasers, laser manufacturing, and large-capacity high-speed laser manufacturing (3D printing).",
