The invention comtemplates promotion or enhanced promotion of vascular or other growth in living body tissue through effectively concurrent in-vivo delivery of at least two beams of laser irradiation at an affected area of body tissue, wherein the irradiation (a) is of low intensity at tissue impingement and (b) is also of spectral wavelength that is preferably in the visible red or in the infrared. Perturbations result in affected cells either directly by reason of differences in the physical properties of the respective beams or indirectly by reason of interaction between the two beams at or near the situs of delivery to the affected body tissue.

Apparatus for enhancement of vascular or other tissue growth by laser irradiation of a local area of living body tissue, comprising laser means producing first and second output beams of identical wavelength, means including a beam splitter for combining said beams for coordinated delivery to and interaction with tissue at said local area, and means operable upon one with respect to the other of said beams for determining a phase shift of one with respect to the other of said beams, the combined intensity of beam delivery to said area being in the range up to 150 microwatts/cm2 and at least sufficient to therapeutically affect beam-impacted body tissue and/or cells but less than sufficient to induce photocoagulation, photovaporization, photonoptical-tissue breakdown, or photoablative decomposition of living tissue and/or cells.
