Abstract
A laser internal coupling modulation arrangement is disclosed wherein a wire grid polarizer serves as one of the reflectors forming part of the laser optical cavity, as a polarization selector which constrains the laser oscillation to a desired linear polarization, and as an output coupler which couples an orthogonal linearly polarized beam out of the laser optical cavity in response to an amplitude varying modulating signal applied to an electrooptic modulator disposed within the laser optical cavity.
