1. A wideband visible light laser, comprising:
a laser cavity resonator comprising a first partial reflector defining the first terminating end of the cavity, and a second end reflector defining the second terminating end of the cavity and wherefrom visible light laser emission exits the cavity; the first and second end reflectors configured for the partial reflection of incident light, and the second reflector configured for the partial reflection of incident light in order to establish optical feedback; a first intra-cavity element comprising a homogeneous gain medium material; a second intra-cavity material element comprising a nonlinear optic material aligned in the cavity with the first intra-cavity element so as to establish optical frequency conversion of the circulating light in the resonator, the second intra-cavity element configured to cause nonlinear feedback of light circulating in the cavity resonator; a first extra-cavity photon noise source element comprising an emission source suitable to enter the first laser resonator cavity through the first partial reflector; the first extra-cavity photon noise source element configured with a specific emission passband profile to cause stimulated emission in the first intra-cavity material within a particular passband; and a first phase-matching structure attendant to the second intra-cavity material element configured to maintain proper phase of the circulating light within the second intra-cavity nonlinear material. |
