| 1 | Titanium dioxide-based Q-switched dual wavelength in the 1 micron region显示文摘In this work a passively Q-switched dual-wavelength ytterbium-doped fiber laser using a titanium dioxide-based saturable absorber is proposed and proven. The system also utilizes a side-polished fiber in a ring cavity configuration to obtain the desired pulse train. A stable dual-wavelength pulse output is obtained at 1034.7and 1039.0 nm, with a maximum pulse energy of 2.0 n J, and a shortest pulse width of 3.2 μs. The generated pulse train is stable, and has a pulse repetition rate from 31.2 to 64.5 kHz. | H.Ahmad M.A.M.Salim Z.A.Ali M.F.Ismail K.Thambiratnam A.A.Latif N.Nayan S.W.Harun | 2016 | Chinese Optics Letters2016，14，9： | 0 |
