Visible Supercontinuum Generation With Sub-Nanosecond 532-nm Pulses in All-Solid Photonic Bandgap Fiber

An all-solid photonic bandgap fiber with the first bandgap from 450 to 900 nm was designed for visible supercontinuum generation. Sub-nanosecond pulses from a 532-nm microchip laser were launched into this fiber, and the supercontinuum from 532 to 900 nm was obtained. The bright single-mode visible light beam was observed, with the output power of 30 mW.
