Claim 24:
25. A machine-implemented method for providing depth-selective trans-oral laser beam delivery, the method comprising:
co-scanning, by a scanning assembly, respective beams in two axes, the respective beams comprising a surgical laser beam comprising monochromatic coherent pulsed light, an optical coherence tomography (OCT) beam comprising incoherent polychromatic light or coherent laser light having a varying wavelength, and a visible aiming beam;
co-focusing the respective beams including at least two visible aiming beam portions, including directing the at least two visible aiming beam portions trans-orally toward a tissue surface and conveying reflections of the visible aiming beam portions to a visualization imager;, generating a presentation of a visible-light visualization of a tissue surface and the reflections of the visible aiming beam portions received by the visualization imager;
acquiring focus on the tissue surface as indicated by the respective visible aiming beam portions spatially converging in the generated presentation, by varying a focus of an optical system; and
tracking motion in two axes using a visible feature in an in-focus generated presentation, for control of the co-scanning.
