Q-Switched All-Fiber Cladding-Pumped Ytterbium-Doped Fiber Lasers

摘要

A Q-Switched All-Fiber Cladding-Pumped Ytterbium-Doped Fiber Lasers using an acoustic-optic waveguide Q-switched (AOW-Q) with a pigtail fiber are studied. For AOW Q-switched, Ti-diffused YX-lithium niobate substrate was applied as optical waveguide, a SiO_2/In_2O_3 film of thickness ～150 nm as acoustic waveguide and an acoustic aperture of width 110μm, in conjunction with N=9 finger pairs.
