A medical laser system for outputting laser pulses includes at least one laser cavity configured to generate at least one laser pulse, a rotating mirror configured to receive and reflect the at least one laser pulse, a beam splitter configured to receive and reflect a portion of the at least one laser pulse received from the rotating mirror, an energy-sensing device configured to detect the portion of the at least one laser pulse, an energy measurement assembly configured to generate a measurement signal based on the portion of the at least one laser pulse detected by the energy-sensing device, and a controller. The controller may include a calibration module. The calibration module may be configured to generate at least one categorized calibration table, determine calibration parameters, interpolate the calibration parameters, and cause the at least one laser cavity to generate at least one calibrated laser pulse.

Systems and methods for calibrating laser pulses

A medical laser system for outputting laser pulses includes at least one laser cavity configured to generate at least one laser pulse, a rotating mirror configured to receive and reflect the at least one laser pulse, a beam splitter configured to receive and reflect a portion of the at least one laser pulse received from the rotating mirror, an energy-sensing device configured to detect the portion of the at least one laser pulse, an energy measurement assembly configured to generate a feedback signal based on the portion of the at least one laser pulse detected by the energy-sensing device, and a controller configured to generate an electronic control pulse based on the feedback signal received from the energy measurement assembly to generate at least one adjusted laser pulse.

Systems and methods for laser pulse monitoring and calibration

A laser system includes a first laser cavity to output a laser light along a first path, a first mirror to receive the laser light from the first laser cavity, and redirect the laser light along a second path that is different than the first path, a second mirror to receive the laser light from the first mirror, and redirect the laser light along a third path that is different than the first path and the second path, a beam splitter located at a first position on the third path, a beam combiner located at a second position on the third path; and a coupling lens assembly, the coupling lens assembly including a lens located at a third position on the third path, wherein the coupling lens assembly moves the lens in x-, y-, and x-directions.

Alignment method and tools

Techniques are provided for controlling an output laser pulse signal of a medical device. A control device defines a time duration of capacitive discharge to a laser device. The time duration corresponds to an intended energy of the output laser pulse signal. The control device generates a plurality of sub-pulse control signals. The sub-pulse control signals define a series of capacitive discharge events of the capacitor bank. The control device modulates one or more of a sub-pulse control signal period or a sub-pulse time duration of the sub-pulse control signals to modify the capacitive discharge of the capacitor bank to the laser device during the time duration.

Systems and methods for controlling laser pulsing

A laser system includes a first cavity to output a laser light along a first path, a first mirror to receive the laser light from the first cavity, and redirect the laser light along a second path that is different than the first path, a beam splitter removably located at a first position on the second path, a beam combiner removably located at a second position on the second path, and an alignment device having first and second alignment features. The first and second alignment features occupy the first position and the second position, respectively, on the second path, when the beam splitter and the beam combiner are removed from the first position and the second position.
