Abstract
Systems and methods for employing an electro-optic and photoconductive optical element operating in combination with a polarizer and 100% reflective mirrors to passively control dumping of power from a resonator. The optical element may be constructed of electro-optic material (e.g., Bismuth Silicon Oxide (BSO), Bismuth Germanium Oxide (BGO)), the refractive index of which may be altered by the application of an externally applied electric field. The presence of incident light changes the photoconductivity of the optical element and, therefore, also changes the polarization state of the light passing through the optical element. When combined with a conventional polarizer, the device acts as a self-triggering optical valve to suddenly divert the path of light within a laser to outside of the normal resonator path. Optical power that has been stored inside the laser resonator is then dumped out of the laser in a single, very-high power pulse.
