  • 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.

  • Publication number: 20210085394
    Abstract: A medical system includes an insertion device including a handle and a delivery portion, a laser fiber, a conductive wire, and a lock. The laser fiber extends through the insertion device and is coupled to a laser slider to control a position of the laser fiber relative to a distal end of the delivery portion. The conductive wire extends through the insertion device and is coupled to a wire slider to control a position of the laser fiber relative to a distal end of the delivery portion. The lock is positioned within the handle and is movable in order to selectively lock either the movement of the laser slider or lock the movement of the wire slider.

    Abstract: A separate-confinement heterostructure, edge-emitting semiconductor laser having a wide emitter width has elongated spaced apart intermixed and disordered zones extending through and alongside the emitter parallel to the emission direction of the emitter. The intermixed zones inhibit lasing of high order modes. This limits the slow axis divergence of a beam emitted by the laser.

  • Patent number: 7903711
    Abstract: A separate confinement heterostructure includes a quantum-well layer bounded by an n-side waveguide layer and a p-side waveguide layer. The waveguide layers guide a lasing mode of the heterostructure. The n-side waveguide layer is composed of indium gallium phosphide (InGaP) and the p-side layer is composed of aluminum gallium arsenide (AlGaAs). The heterostructure is configured such that more than 80% of the optical mode propagates in the n-side waveguide layer.
