Claim 0:
1. A system for performing depth-selective trans-oral laser beam delivery, the system comprising:
a scanning assembly configured to co-scan 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;
an optical system configured to controllably co-focus 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; and
a control system configured to:
generate 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;
acquire 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 the optical system; and
track motion in two axes using a visible feature in an in-focus generated presentation, for control of the scanning assembly.
