International Classification:

A61B 18/20
G03F 7/20
G02F 1/13363

Abstract:

Systems and methods are disclosed for selectively allowing or preventing output of laser pulses. In some embodiments, a laser system comprises a shutter and a shutter motor. The shutter motor is configured to move the shutter in an alternating manner between a first position in which output of laser electromagnetic radiation is allowed a second position in which output of laser electromagnetic radiation is prevented.

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.

A61F 9/008

Abstract:

Systems and methods are disclosed for monitoring a laser system using detection of back reflection. In some embodiments, a laser system comprises a laser, at least one optical fiber, and a back-reflection monitoring sensor for detecting electromagnetic radiation reflected back from the optical fiber(s). The back-reflection monitoring sensor may be adapted to detect back-reflected electromagnetic radiation while the laser system is in use. The laser system may further comprise a computing system adapted to calculate an output power of the system based upon the back-reflected electromagnetic radiation. In some embodiments, a method of monitoring a laser system using detection of back reflection comprises transmitting electromagnetic radiation from a laser, receiving the electromagnetic radiation at one or more optical fibers, and detecting electromagnetic radiation that is back reflected at a back-reflection monitoring sensor.

Appl. No.:

16/805109

Inventors:

- Lake Forest CA, US
Christopher Guerrero - Laguna Niguel CA, US
Daniel Castro - Lake Forest CA, US

International Classification:

F16M 13/02
G02B 7/182

Abstract:

Kinematic mounts are used frequently to hold objects such as mirrors, lenses, and other optical equipment. To adjust kinematic mounts, adjustment mechanisms are often required. Adjustment mechanisms can be used to make fine adjustments in applications where precision is required (e.g., laser system prototyping). Kinematic mounts that include never-before implemented form factors and structural elements require new adjustment solutions, and those solutions are described in this application. Adjustment mechanisms described in this application include a main body, a control frame, and control screws to adjust the orientation of the control frame. The control frame is coupled with a kinematic mount's housing, which rotates about a center of curvature of a bottom surface of the housing.

Abstract:

Kinematic mounts are used frequently to hold objects such as mirrors, lenses, and other optical equipment. To adjust kinematic mounts, adjustment mechanisms are often required. Adjustment mechanisms can be used to make fine adjustments in applications where precision is required (e.g., laser system prototyping). Kinematic mounts that include never-before implemented form factors and structural elements require new adjustment solutions. This application describes systems that include both novel kinematic mounts as well as new adjustment mechanisms developed to reorient the new kinematic mounts. Adjustment mechanisms described in this application include a main body, a control frame, and control screws to adjust the orientation of the control frame. The control frame is coupled with a kinematic mount's housing, which rotates about a center of curvature of a bottom surface of the housing.

Appl. No.:

Inventors:

- Lake Forest CA, US
Christopher Guerrero - Laguna Niguel CA, US

International Classification:

G02B 7/182
F16M 13/02

F16C 11/10

Abstract:

Kinematic mounts disclosed in this application are made from three main components: a housing, a footing, and a tightening mechanism. The tightening mechanism includes three parts: a top portion, a bottom portion, and a locking interface mechanism. When the top portion, which includes a hollow tip with interior threading, is screwed down onto the bottom portion, which includes a threaded tip, the locking interface component is pressed against at least one interior surface of the housing that causes the housing to be pressed against the footing. This action holds the housing in place relative to the footing while simultaneously preventing unwanted movement of the housing during tightening.
