Abstract
An output coupler, for laser cavities with totally reflecting mirrors, hag a beam splitter and a mirror mounted so that the direction of the output beam of the laser is invariant to changes in the output coupling coefficients. The percentage of the laser's energy which is coupled out into an external beam can be continuously varied or varied to obtain the optimum output coupling coefficient and then left set on this value. This device can also be used as a variable beam splitter with an invariant direction for the reflected beam when used external to the cavity of any laser.
