    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: Laser systems and methods are disclosed. One laser system comprises: a plurality of laser resonators, each resonator being operable to discharge an input laser beam; a relay assembly including at least one curved reflective surface that redirects each input laser beam, and reduces a beam size of the redirected beam; a galvo including a curved reflective surface that receives each redirected beam, and outputs a combined laser beam at power level greater than a power level of each laser input beam; and a coupling assembly that reduces spherical aberrations in the combined laser beam, and directs the combined laser beam into an optical fiber. In this system, the combined laser beam may have a maximum beam parameter product lower than a minimum beam parameter product of the optical fiber. Related systems and methods are also disclosed.

    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: In one aspect of the present disclosure, a laser fiber may include an optical fiber. The optical fiber may include a proximal portion. The optical fiber also may include a distal portion having a distal end. The optical fiber may be configured to transmit laser energy from the proximal portion to the distal portion for emission of the laser energy from the distal end. The optical fiber also may include a distal tip surrounding the distal portion to protect the distal portion. The distal tip may include a sheet glass material having a laser energy emitting surface. The laser energy emitting surface may be defined by a chemically-strengthened surface layer.

    Abstract: 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.

    Abstract: A laser system may include a laser resonator configured to emit an input laser beam having an elliptical cross-sectional shape. The laser system also may include first reflective device configured to reflect the input laser beam to produce a first reflected laser beam. The first reflective device may include a spherical surface for reflecting the input laser beam. The laser system also may include a second reflective device configured to reflect the first reflected laser beam to produce a second reflected laser beam. The laser system also may include a coupling device configured to focus the second reflected laser beam to produce an output laser beam. The coupling device may include a spherical surface for receiving the second reflected laser beam. The laser system also may include an optic fiber configured to transmit the output laser beam for emission of the output laser beam onto a target area.
