Optical phased array dynamic beam shaping with noise correction

A method for performing noise correction on a phase varied laser output comprising:

• receiving an output from a seed laser;
• splitting and combining said output to provide a combined laser output having noise;
• applying a noise cancellation phase correction output to said combined laser output based on taking into consideration said noise at intermittent times;
• and
• varying a phase of said combined laser output during time interstices between said intermittent times.

A laser system comprising:

• a seed laser;
• a laser beam splitting and combining subsystem receiving an output from said seed laser, splitting said output into a plurality of sub-beams and providing a combined laser output comprising said plurality of sub-beams, said combined laser output having noise;
• and
• a phase modulation subsystem grouping at least a portion of ones of said plurality of sub-beams into a multiplicity of groups of sub-beams, said phase modulation subsystem:
• in parallel across said multiplicity of groups of sub-beams, varying a phase of each sub-beam within each group relative to phases of other sub-beams within said group so as to vary a phase of each group, and
• varying said phase of each group relative to phases of other ones of said multiplicity of groups, thereby varying a phase of said combined laser output,
• said phase modulation subsystem being operative to provide a noise cancellation phase correction output based on taking into consideration said noise at intermittent times during said varying of said phase of said combined laser output.
