1. A system for performing depth-selective surgical 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;
an optical system configured to controllably co-focus the respective beams in a depth-selective manner;
an ultrafast surgical laser source configured to generate the surgical laser beam to modify a volume of tissue by excision or facilitating hemostasis, or both, according to corresponding operational modes; and
a control system communicatively coupled with the scanning assembly, the optical system, and the ultrafast surgical laser source, the control system configured to establish at least one characteristic of a focused pulse or focused pulses of the surgical laser beam as delivered to a tissue site to selectively enhance hemostasis according to a selected operational mode by increasing a fluence associated with a spot striking a focal location by at least one of (1) adjusting an energy-per-pulse, (2) adjusting a spot size, or (3) adjusting a triggering mode of the ultrafast surgical laser source, as compared to an operational mode corresponding to excising tissue where hemostasis is not enhanced.
