Claim 28:
29. A machine-implemented method for performing depth-selective trans-oral laser beam delivery, the method comprising:
co-scanning, by a scanning assembly, respective beams in two axes to define a first addressable region, the respective beams comprising a surgical laser beam comprising monochromatic coherent pulsed light, and an optical coherence tomography (OCT) beam comprising incoherent polychromatic light or coherent laser light having a varying wavelength;, controllably co-focusing, by an optical system, the respective beams in a depth-selective manner;
adjusting, by electrically-operated actuators of a movable platform, an orientation of the scanning assembly and optical system to move the first addressable region within a larger second addressable region, including controlling the movable platform using the electrically-operated actuators to align the first addressable region with a tissue region of interest; and
generating control data for actuating the optical system to direct the respective beams trans-orally including focusing the surgical laser beam at respective focal planes corresponding to different depths, and at respective depths, actuating the scanning assembly to scan the surgical laser beam across a specified two-dimensional treatment area to excise tissue using at least one of plasma-induced ablation or photodisruption.
