Abstract: Systems and methods are disclosed for a surgical laser system with illumination. In some embodiments, a laser system comprises a surgical laser and an illumination source having their outputs combined into a fiber-optic cable and directed by the fiber-optic cable to a target surface. The illuminating visible light may be continuous and/or in pulses. Surgical laser pulses and illumination pulses may be synchronized for a stroboscopic effect. The laser system may also monitor laser electromagnetic radiation that is returned back through the fiber-optic cable.

Abstract: Systems and methods are disclosed for flexibly controlling laser pulses being output from a laser system. An example surgical system comprises a laser, a laser energy control system configured to regulate the amount of electromagnetic energy of each laser pulse that exits the laser system, and a laser pulse controller. The control signals communicated by the laser pulse controller may include a sub-carrier signal that modulates the amount of electromagnetic energy of the laser pulses that exit the laser system. The control signals may further include a threshold signal and/or a maximum power signal. The sub-carrier signal may oscillate between the threshold power and a maximum power.

Abstract: An ophthalmic system for visualization of interactions between ocular matter and a probe tip of a probe within or in contact with an ocular space of an eye includes: a visualization tool having a field of view that includes at least a portion of the ocular space of the eye where the probe tip interfaces with the ocular matter; and a stroboscopic illumination source configured to stroboscopically illuminate at least the portion of the field of view at an illumination frequency. A method of operating a stroboscopic illumination source during an ophthalmic surgical procedure includes: identifying an illumination source type of the stroboscopic illumination source; identifying a probe type; identifying a first procedure trigger; and operating the stroboscopic illumination source based on the probe type, the illumination source type, and the first procedure trigger.
