  • Low noise optically pumped laser structures utilizing dispersion elements
    Patent number: 9008144
    Abstract: A refractive optics-based dispersion control structure for a low-noise solid state laser standing-wave resonator has at least one dispersive element, a gain medium, and a frequency doubling element disposed in the resonant beam path. The dispersive element provides geometric-based laser bandwidth control that minimizes the laser output power noise. The dispersive element in certain embodiments may be a prism. The dispersive element in certain other embodiments may be integrally formed with the gain medium. Numerous different architectures using these elements are disclosed.
