  • High-power red, orange, green, blue (ROGB) fiber lasers and applications thereof
    Patent number: 7280567
    Abstract: An all-fiber device platform for producing high-power ROGB or RGB laser output comprises an optical fiber including multiple waveguide gain regions embedded within a common inner cladding and within an outer cladding, an optical cavity defined by dielectric reflectors and/or FBG mirrors, and a pump source for exciting one or more active ionic species by one or multiple pump wavelengths from one or both ends of the optical fiber through upconversion process. An apparatus for producing sequential or simultaneous multiple wavelength laser operation provides for applications of color projection displays and biomedical or other instrumentation.
    Type: Grant
    Filed: March 10, 2005
    Date of Patent: October 9, 2007
    Inventors: Ningyi Luo, Feng Zhou, Sheng-Bai Zhu, Yuxing Zhao
