Abstract
Amplitude noise is dramatically reduced in an optically pumped modelocked laser arrangement by incorporating an intra-cavity or external cavity mode selection element with a continuous-wave pump laser coupled optically to a modelocked laser. The mode selection element causes a light beam generated from the pump laser to operate nominally at a single frequency, that is, substantially a single longitudinal mode. Mode selection may be realized with an air-spaced or solid material Fabry-Perot etalon.
