Abstract
Output for a laser is greatly increased by altering the transmitivity of a superconductor layer which serves as one of the mirrors of the laser cavity. The superconductor layer is switched between a superconductive state, having reflectivity of one, and a non-superconductive state, having a reflectivity of less than one. When the mirror is in its superconducting state, output power is decreased and power in the cavity is increased, and when the mirror is in its non-superconducting state, output power of the laser is increased and power in the cavity decreases.
