ABSTRACT:
A ring laser for a ring laser type of gyro having a block with an optical resonator cavity therein and three corner mirrors and an amplifier element for optical frequencies. The amplifier element is adjustable and alignable with respect to the block in such a way that it is adaptable mechanically to the beam path resulting from the mirror arrangement determined by the production technology. The production depends basically on arranging the mirrors in such a way that a resonant beam path results. As tolerances with regard to the accuracy of the position of the amplifier element are considerably lower than those with regard to the positions of the mirrors, the position of the amplifier element is specified.
