  • High yield diffraction limited laser oscillator
    Patent number: 4276519
    Abstract: The laser oscillator comprises an optical amplifying medium and a diaphragm disposed between two mirrors defining a cavity. The diaphragm is placed between the amplifying medium and the mirror having a high coefficient of reflection. A polarizer is placed between the diaphragm and the amplifying medium. A device for rotating the polarization of the output beam of the oscillator and for transforming and returning this beam by reflection to the amplifying medium and the polarizer is provided so that, when the beam again reaches the amplifying medium, it has a section roughly equal to the section of the amplifying medium.
