Abstract
A laser diode produces a laser beam having a carrier frequency component and a sideband frequency component. An optical resonator receives the laser beam and substantially couples the carrier frequency component and substantially rejects the sideband frequency component. An electronic locking system receives the rejected sideband frequency component and adjusts the laser diode to lock the carrier frequency component to the resonator frequency. A laser control controls the allocation of power between the carrier frequency and the sideband frequency component such that the resonator output may be controlled and pulsed.
