A holey-fiber-based white-light source developed by researchers at the University of Southampton's Optoelectronics Research Centre (Southampton, England) produces red and blue sidebands from green input light, resulting in an RGB (red-green-blue) spectral distribution potentially useful for laser-projection displays. The source relies on four-wave mixing to convert a portion of the 530 nm light from a frequency-doubled pulsed-fiber master-oscillator power-amplifier source to wavelengths of approximately 460 and 625 nm.
