We demonstrate coherent beam combining of two-dimensional fiber amplifier arrays with a total of 137 W output power using stochastic parallel gradient descent (SPGD) algorithm. Compact all-fiber polarizationmaintained single frequency fiber amplifier chains are developed and four fiber amplifiers ar
