摘要: A GeO2 doped triangular-core photonic-crystal fiber (PCF) is designed and fabricated to allow the generation of a hollow beam through nonlinear-optical transformation by femtosecond pulses at 1040 nm from high power Yb-doped PCF laser oscillator. The supercontinuum obtained far field adjusting incident light polarization excite order supermode, behaving as mode convertor. ranging 540 1540 achieved with an average 1.04 W.
