Abstract: A device for performing treatment of biological tissue that includes a laser system configured to provide a laser beam having a wavelength within a range of 3.0 microns (?m) to 3.25 ?m inclusive and a spot size within a range of 10 ?m to 45 ?m inclusive, and a controller coupled to the laser system and configured to scan the laser beam over the biological tissue in an injury pattern, the injury pattern having a pitch that is sized to be in a range of 0.1 mm to 1 mm inclusive.

Abstract: A method for controlling a surgical laser system that includes providing a surgical fiber configured to receive light reflected from a target in a surgical treatment area, and providing a computing device configured to couple with at least two photodetectors, each photodetector configured to detect an intensity of reflected light from the target in a different selected wavelength band, the computing device further configured to: receive the reflected light intensity in at least two selected wavelength bands, generate optical data corresponding to the reflected light intensity, and identify the target as a treatment target or a non-treatment target based at least in part on the optical data and a predetermined calibration based on at least two known targets.

Abstract: A surgical laser system includes a surgical optical fiber optically coupled to a light source and a light detector configured to receive a portion of light reflected from a treatment target and generate optical data corresponding to the portion of the reflected light interacting with the light detector. The system also includes a computing device configured to analyze the optical data relative to characteristic criteria, and based on the comparison of the optical data to the characteristic criteria, control operation of a laser source.

Abstract: The disclosed method and apparatus for stabilizing a mode-locked regime of a fiber ring oscillator based on a NPR include tapping a portion of light, which has a broad spectral bandwidth, from a fiber ring resonator into at least first and second control channels. The control channels are configured to guide respective first and second fractions of the tapped portion. One of the control channels is provided with a bandpass filter operative to extract a region from the broad spectral bandwidth. The fractions with respective full spectral bandwidth and region thereof are then evaluated in a central processing unit which is operable to generate a control signal if a predetermined criterion is not met. The control signal is received by one or more polarization controller units operative to dynamically modulate a state of polarization of light in the fiber ring resonator until the evaluation meets the predetermined criterion.
