    Abstract: In certain embodiments, a system for sensing occlusions in an optical system includes a first laser source configured to generate optical signals and a set of optical elements arranged to receive the optical signals from the first laser source and to direct the optical signals along a beam path. The system also includes a detector arranged to receive reflections of the optical signals traveling along at least a portion of the beam path and a control system communicably coupled to the detector. The control system is configured to detect, based on signals generated by the detector, reflection signals associated with the reflections of the optical signals, and disable a second laser source based on detection of the reflection signals.

    Abstract: Systems and methods are disclosed for measuring pulsed laser output. An example system comprises a laser configured to emit output in pulses; at least one sensor positioned to sense laser output and configured to convert that output into electrical signals; an edge detector configured to detect at least leading edges of a plurality of laser pulses; an analog to digital converter configured to convert electrical signals from a sensor into digital signals indicative of laser power output; and a controller; wherein, based on the detection of at least the leading edges of the laser pulses, the controller is configured to obtain samples of laser power output during the laser pulses. The system may refrain from sampling laser power output between laser pulses or may sample laser power output between laser pulses at a reduced sample rate. The system may use the samples of laser power output in a feedback loop to automatically adjust laser power.

    Abstract: Certain embodiments describe an endoilluminator comprising a probe housing an optical fiber. The probe comprises a distal end with an opening through which a first light from a distal end of the optical fiber is configured to be propagated. The probe comprises one or more side openings through which a second light from one or more sides of the optical fiber is configured to be propagated. The endoilluminator also comprises a handpiece coupled to a light source and the proximal end of the probe, wherein the light source is configured to drive light into the optical fiber.
