  • Laser assembly for ladar in missiles
    Patent number: 6724470
    Abstract: A device for generating a laser beam in a LADAR system has a master oscillator with a laser-active medium and an amplifier stage in the form of a fiber optic power amplifier. This power amplifier amplifies the power of the oscillator. A carrier body is provided, on which a length of fiber of the power amplifier is coiled. The carrier body consists of a material of high thermal conductivity. The master oscillator may be a microchip laser. Diode lasers are used as pump light sources for the fiber optic power amplifier. This assembly can be made lightweight and compact, whereby it is particularly suitable for use in missiles.

  • Methods for measuring the sorbate content of substrates
    Patent number: 6178812
    Abstract: The invention relates to methods for measuring the sorbate content in substrates, using a sensor with a measuring chamber. Said chamber contains a support medium whose partial pressure of sorbate is determined in order to determine the sorbate content of the substrate. According to the first method, the temperature of the support medium is varied up to a value at which the partial pressure of sorbate in the measuring chamber no longer varies with the temperature of the support medium, and slightly over this value. This partial pressure of sorbate is then used to determine the sorbate content of the substrate. According to the second method, the temperature of the support medium is kept essentially constant and the speed at which the partial pressure of sorbate of the support medium approaches the stable end value is determined.
