Abstract
The intracavity modulated laser includes a main cavity and an adjacent coed cavity with a gain cell in the main cavity and an electro-optic modulator in the coupled cavity, the cavities being coupled in such a way that the energy level in the coupled cavity during laser operation is much lower than that in the main cavity, and whereby the modulator can selectively affect the polarization of energy in accordance with a voltage applied thereto to selectively couple energy out of both cavities in a desired manner.
