1Self-Starting Harmonic Mode-Locked Thulium-Doped Fiber Laser with Carbon Nanotubes Saturable Absorber显示文摘We report a ring cavity passively harmonic mode-locked thulium-doped fiber laser(TDFL)using a newly devel-oped single-wall carbon nanotube-based saturable absorber.The TDFL generates the 25 th harmonic mode-locked stretched pulse train with a high repetition rate of 213MHz and a pulse duration of 710fs.The laser operates at 1901.6nm with an average power of 1.89mW,which corresponds to the pulse energy of 0.008nJ,at 1552nm pump power of 719mW.The peak-to-background ratio is measured to be 60dB,which indicates the stability of the laser.S.W.Harun N.Saidin D.I.M.Zen N.M.Ali H.Ahmad F.Ahmad K.Dimyati 2013Chinese Physics Letters2013,30,9:0
2Self-starting harmonic mode-locked Tm-Bi co-doped germanate f iber laser with carbon nanotube-based saturable absorber显示文摘We report a ring cavity passively harmonic mode-locked fiber laser using a newly developed thuliumbismuth co-doped fiber(TBF) as a gain medium in conjunction with a carbon nanotube(CNT)-based saturable absorber.The TBF laser generates a third harmonic mode-locked soliton pulse train with a high repetition rate of 50 MHz and a pulse duration of 1.86 ps.The laser operates at 1 901.6 nm with an average power of 6.6 mW,corresponding to a pulse energy of 0.132 nJ,at a 1 552 nm pump power of 723.3 mW.N.Saidin D.I.M.Zen S.S.A.Damanhuri S.W.Harun H.Ahmad F.Ahmad K.Dimyati A.Halder M.C.Paul M.Pal S.K.Bhadra 2013Chinese Optics Letters2013,11,6:0
3A Tm-Bi Co-Doped Fiber Laser with Dual Pumping Operation显示文摘We demonstrate an efficient fiber laser operating at 1901.6 nm using a newly developed thulium bismuth co-doped fiber(TBF)with dual pumping at 792 nm and 1552 nm.The fiber was fabricated using modified chemical vapor deposition and solution doping processes.The dopant concentrations(wt%)and compositions inside the core are 0.15 Bi_(2)O_(3),0.3 Tm_(2)O_(3),1.0 Al_(2)O_(3) and 12.0 GeO_(2).The TBF laser operates at 1901.6 nm with a lasing efficiency of 33.2%and pump power threshold of 85 mW using a 2-m-long TBF in a linear cavity with two fiber Bragg gratings(FBGs).The high efficiency is attributed to the use of additional 1552 nm pump to complement 792 nm pumping.The maximum output power of 225 mW is achieved at the pump power of 820 mW with the optimum length of 2 m.N.Saidin S.W.Harun S.S.A.Damanhuri S.M.M.Ali H.Ahmad A.Halder M.C.Paul S.Das M.Pal S.K.Bhadra 2013Chinese Physics Letters2013,30,3:0
