  • Publication number: 20220079673
    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.

  • Publication number: 20210098959
    Abstract: Techniques are provided for controlling an output laser pulse signal of a medical device. A control device defines a time duration of capacitive discharge to a laser device. The time duration corresponds to an intended energy of the output laser pulse signal. The control device generates a plurality of sub-pulse control signals. The sub-pulse control signals define a series of capacitive discharge events of the capacitor bank. The control device modulates one or more of a sub-pulse control signal period or a sub-pulse time duration of the sub-pulse control signals to modify the capacitive discharge of the capacitor bank to the laser device during the time duration.

  • Patent number: 9531148
    Abstract: A laser resonator comprises a cylindrical gain medium, a cooling system and a coupling member. The cylindrical gain medium comprises a central axis, an outer side surface, two opposing end faces and a first depression in the outer side surface. The cooling system comprises a cooling jacket disposed around the gain medium that defines a cooling cavity, in which cooling fluid is guided over the side surface of the gain medium. In one embodiment, the cooling jacket comprises a second depression. The coupling member is received within the first and second depressions. Movement of the first depression along the central axis relative to the cooling jacket is restricted by the coupling member.
