Abstract
Coherent beam combining of an 800 W nanosecond single-frequency fiber amplifier array has been demonstrated. Five high-power all-fiberized Yb-fiber amplifiers were tiled into a crisscross array, and the laser beams were actively phase-locked by using the stochastic parallel gradient descent algorithm. The contrast of the far-field intensity pattern of the combined beam was more than 91.6%. The combined pulsed laser has a pulse width of
