摘要： A dichroic optical filter including a substrate that is substantially transparent to visible radiation, and an oxide semiconductor layer on the substrate for reflecting an infrared wavelength (such as an infrared treatment beam wavelength). An example of a suitable oxide semiconductor for reflecting a treatment beam from a CO.sub.2 layer is indium tin oxide. Preferably, the filter includes a specially designed multilayer coating on the oxide semiconductor layer to enhance the reflection of infrared and longer wavelength radiation. This multilayer coating includes alternating quarter-wave layers of high and low refractive index materials, each having an optical thickness substantially equal to a quarter-wavelength of infrared radiation to be reflected. Preferably also, the multilayer coating includes a thin multilayer coating between each pair of adjacent quarter-wave layers, with these thin multilayer coatings being designed to enhance the filter's transmission of visible radiation, while not significantly affecting the filter's reflection of infrared wavelengths. Also preferably, the multilayer coating includes a second multilayer coating which reflects a narrow band of visible radiation (such as visible radiation from a HeNe laser aiming beam), while transmitting most visible wavelengths.

摘要： A waveguide including a folded, coated reflector highly reflective of radiation having two different wavelengths over a wide range of incidence angles, including grazing incidence angles. The waveguide can be employed for guiding laser radiation useful for medical or other applications, such as a combined HeNe and CO.sub.2 laser beam. In some embodiments, the invention is a hollow waveguide formed by folding a flat, coated substrate into a polygonal shape. Because the coated substrate is folded, rather than rolled into a cylindrical tube, the bending stress on the coating is concentrated at the corners of the polygonal waveguide rather than distributed over the waveguide's entire surface. Although the coating may crack at the corners of the waveguide's polygonal cross-section, the flat surfaces between the waveguide edges will be intact, and the cracks in the corners will have an insignificant effect on waveguide performance.

摘要： 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.

摘要： A vacuum compatible linear motion device having a fluid bearing is contained within a vacuum chamber having a working pressure of significantly less than one atmosphere. The fluid bearing is contained within a vacuum enclosure within the vacuum chamber and is maintained at a pressure higher than that of the vacuum chamber but less than one atmosphere, thus essentially isolating the fluid bearing. A moveable payload is coupled to the linear motion device such that linear motion in the direction of the long axis of the device is provided to the moveable payload.

摘要： 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.

摘要： Typically, a laser emits significant energy after a control signal is generated to disable the power supply. The inherent delay between generation of a control signal for shutting off a laser power supply and actual termination of an output beam pulse in response to the control signal, is compensated in the context that the control signal is generated automatically upon coincidence of measured output beam power with a preset threshold value. Power supplied to a laser is modulated to cause generation of a pulsed laser output beam. The cumulative energy of each output beam pulse is monitored and a feedback signal indicative of measured output beam pulse energy is supplied to the power supply. The feedback signal is compared with a user-selected threshold value, and a control signal is generated for terminating the output beam pulse (by terminating input power to the laser) when the measured output pulse energy reaches the threshold value. By generating the threshold signal to have a value representing a threshold output beam pulse energy that is lower than a desired output beam pulse energy, the threshold signal is generated in a manner which compensates for the inherent delay between generation of the control signal and the actual termination of the output beam pulse in response to the control signal. This prevents delivery of significant output beam energy in excess of a user-selected amount.

摘要： A pulsed solid state laser system is disclosed which utilizes a plurality of individual laser rods which are sequentially pumped and whose beans are combined into a single interleaved output bean. The individual laser rods are pumped at an average power level which is below that for maximum output power from each rod, thereby obviating the need for refrigeration cooling. A compact optical system is disclosed which permits a constant beam size even at different pump levels and other advantages. A compact cooling system is also disclosed.

摘要： An electron beam pattern generating system for exposing a pattern on a substrate using a raster scan method. The system stores a rasterized representation of the pattern as a plurality of regular pixel dose exposure levels. These pixel dose exposure levels are evaluated by the system for one or more proximity effects and corrections to the dose exposure level and/or pixel location are calculated. The system includes apparatus for both calculation and storage of intermediate and final results as required. As they are calculated, the corrections are provided to an exposure dose modulator wherein they are applied to forming the pattern. Thus corrections for both long range and short range proximity effects due to both electron scattering and heating as well as for proximity effects due to global thermal expansion can be calculated and provided during run-time and a corrected pattern exposed.
