Abstract: A surgical laser system (100) includes a first laser source (140A), a second laser source (140B), a beam combiner (142) and a laser probe (108). The first laser source is configured to output a first laser pulse train (144, 104A) comprising first laser pulses (146). The second laser source is configured to output a second laser pulse train (148, 104B) comprising second laser pulses (150). The beam combiner is configured to combine the first and second laser pulse trains and output a combined laser pulse train (152, 104) comprising the first and second laser pulses. The laser probe is optically coupled to an output of the beam combiner and is configured to discharge the combined laser pulse train.

Abstract: Aspects of the disclosure are drawn to methods for producing a fused connector termination. An exemplary method may include setting a specification requirement to be met by the fused connector termination and applying an amount of heat to a proximal region of an unfused connector termination. The proximal region of the unfused connector termination may include an inner optical fiber coaxially positioned within an outer ferrule, and applying the amount of heat may at least partially fuse the optical fiber to the outer ferrule to form an at least partially fused connector termination. The method may also include imaging the proximal region of the at least partially fused connector termination and determining, based on the imaging, whether the proximal region of the at least partially fused connector termination meets the specification.

Abstract: Aspects of this disclosure pertain to a device with an elongated body having a distal end. The distal end may comprise a port that permits discharge of a laser energy towards a tissue from an optical fiber located in the distal end. An exterior surface of the distal end may include a cauterization portion that permits discharge of a cauterization energy towards the tissue. In some aspects, the device includes an insulative portion that attaches the distal end to the elongated body and limits energy transfer therebetween. Related systems and methods are also disclosed.

Abstract: A system may include a stone analyzer, a controller, a laser generator, and a beam combiner. The stone analyzer may be configured to generate an output relating to a natural or resonance frequency of a kidney or bladder stone. The controller may be configured to determine the natural or resonance frequency of the stone based on the output from the stone analyzer, and match a resultant pulse repetition rate with the natural or resonance frequency. The laser generator may be configured to generate at least two laser pulse trains, with each laser pulse train including laser pulses at a pulse repetition rate. The beam combiner may be configured to combine the at least two laser pulse trains into a combined laser pulse train including laser pulses at the resultant pulse repetition rate.
