主 题:waveguide lasers nanoparticles localized surface plasmon resonance saturable absorption
摘 要:Copper(Cu)nanoparticles(NPs)are synthesized under the near-surface region of the Nd∶Y_(3)Al_(5)O_(12)(Nd:YAG)crystal by direct Cu^(+)ions ***,the monolithic ridge waveguide with embedded Cu NPs is fabricated by C^(4+)ions irradiation and diamond saw *** nonlinear optical response of the sample is investigated by the Z-scan technique,and pronounced saturable absorption is observed at the 1030 nm femtosecond *** on the obvious saturable absorption of Cu NPs embedded Nd:YAG crystal,1μm monolithic mode-locked pulsed waveguide laser is implemented by evanescent field interaction between NPs and waveguide modes,reaching the pulse duration of 24.8 ps and repetition rate of 7.8 *** work combines waveguides with NPs,achieving pulsed laser devices based on monolithic waveguide chips.
