    Abstract: An improved apparatus for manually manipulating a surgical laser beam is disclosed. The preferred embodiment of the invention includes a mirror nominally positioned at a 45 degree angle to the incident laser beam, a joy stick for manipulating the mirror, and a linkage interconnecting the two. The mirror is mounted to allow it to rotate about two mutually perpendicular and intersecting axes. The linkage operates to direct the reflected laser beam in two orthogonal dimensions such that a ratio between the movement of the reflected beam in each dimension is equivalent to the ratio of the movement of the joy stick in each dimension. This yields a reflected laser beam that moves a distance proportional to the amount of motion input to the joy stick. The reduction or amplification ratio between the input motion and the reflected laser beam motion remains constant, regardless of the direction of motion. In this manner, by moving the joy stick in a circular motion, the reflected laser beam also moves in a circular motion, rather than in an elliptical motion. A simplified joint that allows spherical rotation and axial translation between its two members is also disclosed. In the preferred embodiment, an adjustable hand rest is provided that moves out of the way when not in use.

    Abstract: Disclosed is a positioning stage for precisely positioning an object within a limited range of travel (e.g. 100 &mgr;m). By way of example, the stage can be used to position an electron source such as a field emitter in an electron beam microcolumn. The stage includes a block which defines a channel to allow flexure along a first axis. The block also defines another channel to allow flexure along a second axis perpendicular to the first axis. Using actuators in the channels to flex a portion of the block, the object supported by the block can be precisely positioned to a desired location in a horizontal plane defined by the first and second axes.

    Abstract: A handpiece for use in delivering the output beam of a laser to the surface of a patient's skin for performing a dermatological procedure. In a first and second embodiment of the present invention, the handpiece provides a highly collimated beam of a fixed, non-variable spot size which is largely insensitive to movement of the handpiece over a range of working positions. In a third embodiment the handpiece provides a highly collimated and well defined focused laser spot of variable size where for a selected spot size, the size is largely insensitive to movement of the handpiece over a range of working positions. In all of the embodiments, the highly collimated laser beam permits the surgeon performing the procedure to move the handpiece over a range of positions without significantly defocusing or altering the spot size of the beam.

    Abstract: A pulse format for a laser system is disclosed for maximizing the energy delivered to a target immersed in an absorbing liquid. A first pulse is generated having an energy sufficient to initiate the formation of a vapor bubble in the liquid medium adjacent the end of the delivery device. A second, high energy pulse is generated after the vapor bubble initiated by the first pulse has expanded an amount sufficient to displace the liquid between the delivery device and the target. In this manner, the second pulse is delivered directly to the target and little energy is lost to the liquid medium.

    Abstract: A beam delivery apparatus, including a set of focusing mirrors (or transmissive lenses) mounted along an endoscope channel. A laser beam can be focused into an input end of the channel with a smaller F number (wider cone angle) than is possible in a conventional endoscope. As the beam propagates down the channel, it is reflected (or transmitted) a finite number of times by the focusing elements. The focusing elements act as a periscope to focus and refocus the beam as it propagates along the channel, with little loss of beam power. The invention enables delivery of the beam to the channel's distal end with a smaller F number than can be achieved using a conventional endoscope. In a preferred embodiment, a pair of reflecting strips are mounted the channel, the surface of each strip defines six focusing mirrors, and the beam undergoes a total of twelve reflections from the mirrors as it propagates down the channel. Preferably, the surface of each mirror has a curvature selected to prevent the introduction of astigmatic distortion during each beam reflection.
