Abstract
A means and method for phase stabilization and sorting of wavetrains of electromagnetic energy comprising: splitting an input beam into a plurality of intermediate beams; directing the intermediate beams along separate delay paths so that wavetrains from the delayed beams overlap each other and bridge gaps between wavetrains; producing interference with the delayed beams at a plurality of locations at an image component separator, and separating energy at each location, phase-adjusting and directing it into at least one output, thereby providing a wavetrain phase stabilizer having a substantially constant phase output by phase-matching overlapping wavetrains. Multiple outputs may be added to facilitate wavetrain sorting. Inserting the invention into the feedback path of a laser provides phase-stabilized continuous-wave laser light.
