摘 要：As miniature fibre-optic platforms,micro/nanofibres(MNFs)taper-drawn from silica fibres have been widely studied for applications from optical sensing,nonlinear optics to optomechanics and atom *** continuous-wave(CW)optical waveguiding is frequently adopted,so far almost all MNFs are operated in low-power region(e.g.,0.1 W).Here,we demonstrate high-power low-loss CW optical waveguiding in MNFs around 1550-nm *** show that a pristine MNF,even with a diameter down to 410 nm,can waveguide an optical power higher than 10 W,which is about 30 times higher than demonstrated ***,we predict an optical damage threshold of 70 *** highpower CW waveguiding MNFs,we demonstrate high-speed optomechanical driving of microparticles in air,and second harmonic generation efficiency higher than those pumped by short *** results may pave a way towards high-power MNF optics,for both scientific research and technological applications.
