Abstract: A surgical laser system includes an array of laser diodes that are configured to output laser energy, a fiber bundle, a delivery fiber, and a tubular sheath. The fiber bundle includes a plurality of optical fibers and has a proximal end that is configured to receive laser energy from the array of laser diodes. The delivery fiber includes a proximal end that is configured to receive laser energy from a distal end of the fiber bundle. The tubular sheath defines a lumen, in which at least a portion of the delivery fiber is disposed. The tubular sheath is insertable into a working channel of an endoscope or a cystoscope. A distal end of the tubular sheath is configured to deliver laser energy discharged from the delivery fiber into a body of a patient.

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 surgical laser system includes a first laser source, a second laser source, a beam combiner and a laser probe. The first laser source is configured to output a first laser pulse train comprising first laser pulses. The second laser source is configured to output a second laser pulse train comprising second laser pulses. The beam combiner is configured to combine the first and second laser pulse trains and output a combined laser pulse train 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: In a method, a laser pump module is set to a first power mode and pump energy is output at a first power level through the activation of a first subset of laser diodes. Laser light is emitted from a gain medium at the first power level in response to absorption of the pump energy. An operator input corresponding to a power mode setting is received. The laser pump module is switched to a second power mode and pump energy is output at a second power level through the activation of a second subset of the laser diodes. Laser light is emitted from the gain medium at the second power level in response to absorption of the pump energy.
