  • Laser total reflectometer
    Patent number: 4073590
    Abstract: A device for measuring the total reflectivity, i.e., specular plus scatter, f a small area of a material at various laser frequencies and intensities. The device includes appropriate transmitting and collecting optics in conjunction with a thermopile-type energy sensor with an external metering circuit. The metering circuit can be quickly adjusted to read total reflectivity of a sample placed in front of the reflectivity-measuring device.

  • Aspheric cassegrain laser power amplifier system
    Patent number: 3942127
    Abstract: An optical power amplifier system for extracting high power radiation from a basic active laser media. The system includes a plurality of basically confocal mirrors so positioned that radiation output from a laser is amplified, that no power is absorbed in the supporting structure and it has no feedback from the secondary mirror. In the system, the laser beam passes through the active laser media region at least four times which increases the output power.
