摘要： The present application discloses a method and apparatus for making a low cost and highly efficient hollow waveguide for transmitting electromagnetic radiation. The waveguide is made from a solid substrate monolithic hollow tube with a reflectivity enhancing dielectric film formed directly over the inner surface. The film can be formed by native chemical reactions, with the material of the monolithic, hollow tube. The present application also discloses a method of polishing and cleaning the inner surface of the hollow tube. One of the problems identified with the hollow metallic waveguide has been the poor surface finish on the inner wall of the hollow tube which results from the processes used to fabricate the metallic tube into final form. The coated reflectivity enhancing dielectric films more or less duplicate the surface roughness in the as formed tube thus seriously affecting the performance of the waveguide especially at the shorter wavelengths. The interior surface of the as received metal tubes can be significantly improved by chemically polishing and cleaning the tube and thereby improving the transmission characteristic of the wave guides for both infrared and visible wavelengths.

摘要： A scanning laser radar system utilizing a frequency modulated (fm)-continuous wave (cw) beam to coherently detect echo signal returns from an object in a predetermined region. The frequency of the beam is repeatedly changed as a function of time to produce a symmetrical triangular-shaped frequency modulated waveform. The echo signals received are frequency shifted, as a function of range and Doppler shift, from the signal being transmitted at that time. The frequency shift is detected by homodyning a portion of the instantaneous transmitted signal with the received echo signal to produce an output signal having a frequency which is substantially constant during a portion of the frequency modulation period. The constant frequency portion of the output signal is related to the range and Doppler speed of the target. Target information such as range, Doppler speed, intensity and angle information are derived by processing the output signal. The signal to noise ratio of the output signal is improved by using a frequency modulation period greater than the scanning time across an arc of a size equal to a predetermined multiple of the beamwidth because with such relationship the time duration of the constant amplitude portion of the output signal is increased. Further, with such arrangement, because of the relatively long modulation period, the ambiguity in detection of the range to the target is reduced. The system is particularly useful in terrain following or obstacle avoidance applications.

摘要： A laser is provided comprising a laser envelope and a gain medium disposed in the laser envelope. The gain medium comprises a compound subject to dissociation into a plurality of components. Circuitry is included for generating an electrical discharge in the laser envelope, a portion of the electrical discharge passing through the gain medium and disassociating a portion of the compound thereof into the plurality of components. The discharge generating circuitry comprises a cathode, the cathode comprising a first portion for emitting the electrical discharge toward an anode. Such first portion comprises a catalyst for aiding the recombination of the dissociated plurality of components. The first portion of the cathode sputters particulates therefrom during the electrical discharge and a surface is disposed within the laser envelope for collecting the sputtered particulates. Means, including a second portion of said cathode, are additionally provided for spacing the first portion of the cathode sufficiently from the collecting surface to substantially prevent the electrical discharge from being emitted from the first portion to the collected particulate, and thereby constrain the electrical discharge to occur substantially directly between the cathode and the anode. With such arrangement, the sputtered particulates are inhibited from entering the resonant cavity of the laser and adhering to the optics thereof. Thus, the useful operating life of the laser is increased.

摘要： Laser power is delivered at normal intensities or powers to the end of a laser guide such as an articulated arm from a laser console where the beam enters an attached attenuating unit. Inside the attenuator, the beam encounters a dual wavelength beam splitter that transmits an attenuated beam at, for example, 20 times reduction of power. The attenuated beam may be delivered to an area of medical treatment. The beam splitter is also reflective and reflects the remaining power to a power sensor where the thermal energy is absorbed and measured. The power of the attenuated beam is related to the power of the measured reflected beam. The beam splitter is coated to allow maximum transmission of a visible guide beam that always travels coaxially to the operating laser energy being attenuated. A signal from the power sensor is provided to a preferably battery powered read-out device that provides the surgeon with real time accurate readings of delivered power.
