Abstract: A surgical laser system includes a pump module configured to produce pump energy within an operating wavelength, a gain medium configured to convert the pump energy into first laser energy, a non-linear crystal (NLC) configured to convert a portion of the first laser energy into second laser energy, which is a harmonic of the first laser energy, an output, and a first path diversion assembly having first and second operating modes. When the first path diversion assembly is in the first operating mode, the first laser energy is directed along the output path to the output, and the second laser energy is diverted from the output path and the output. When the first path diversion assembly is in the second operating mode, the second laser energy is directed along the output path to the output, and the first laser energy is diverted from the output path and the output.

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.

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.
