ABSTRACT:
Light from a master laser is divided into multiple beams. Each of the beams is imaged onto a slave laser in a slave laser array. The multiple beams injection lock the frequency of each laser in the slave laser array to the frequency of the master laser. Some of the output light from the array of slave lasers is directed onto an optical wavefront measurement sensor which measures spatial variation in light phase and intensity. A computer responsive to the output of the optical wavefront measurement sensor controls the injection current to each laser in the slave laser array to adjust dynamically the relative phase of each laser in the array so as to synthesize a desired wavefront.
