主 题:higher-order mode delocalisation high-power fibre lasers and amplifiers photonic-crystal fibre very large mode area
摘 要:Rare earth-doped fibres are a diode-pumped,solid-state laser architecture that is highly scalable in average *** performance of pulsed fibre laser systems is restricted due to nonlinear ***,fibre designs that allow for very large mode areas at high average powers with diffraction-limited beam quality are of enormous ***-doped,rod-type,large-pitch fibres(LPF)enable extreme fibre dimensions,i.e.,effective single-mode fibres with mode sizes exceeding 100 times the wavelength of the guided radiation,by exploiting the novel concept of delocalisation of higher-order transverse *** non-resonant nature of the operating principle makes LPF suitable for high power *** design allows for an unparalleled level of performance in pulsed fibre lasers.
