| 1 | A Q-Switched Erbium-Doped Fiber Laser with a Carbon Nanotube Based Saturable Absorber显示文摘We demonstrate a simple,compact and low cost Q-switched erbium-doped fiber laser(EDFL)using single-wall carbon nanotubes(CNTs)as a saturable absorber for possible applications in metrology,sensing,and medical diagnostics.The EDFL operates at around 1560 nm with repetition rates of 16.1 kHz and 6.4 kHz with saturable absorbers SA1 and SA2 at a pump power of 120 mW.The absorbers are constructed by optically driven deposition and normal deposition techniques.It is observed that the optical deposition method produces a Q-switched EDFL with a lower threshold of 70 mW and better Q-switching performance compared to that of the normal deposition method.The EDFL also has pulse energy of 90.3 nJ and pulse width of 11.6μs at 120 mW pump power. | S.W.Harun M.A.Ismail F.Ahmad M.F.Ismail R.M.Nor N.R.Zulkepely H.Ahmad | 2012 | Chinese Physics Letters2012，29，11： | 0 |
| 2 | 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 |
| 3 | Optically Modulated Tunable O-Band Praseodymium-Doped Fluoride Fiber Laser Utilizing Multi-Walled Carbon Nanotube Saturable Absorber显示文摘A tunable and optically modulated fiber laser utilizing a multi-walled carbon nanotube based saturable absorber is demonstrated for operation in the O-band region.A praseodymium-doped fluoride fiber is used as the gain medium and the system is capable of generating modulated outputs at 1300 nm.Pulsed output is observed at pump powers of 511 mW and above,with repetition rates and pulse widths that can be tuned from 41 kHz and 3.4μs to 48 kHz and 2.4μs,respectively,at the maximum pump power available.A maximum average output power of 100μW with a corresponding single pulse energy of 2.1 nJ is measured,while the tunability of the proposed laser is from 1290 nm to 1308 nm.The output is stable,with peak power fluctuations of^4 dB from the average value. | H.Ahmad M.F.Ismail S.N.Aidit | 2019 | Chinese Physics Letters2019，36，10： | 0 |
