چکیده
Mode-locking is an ultra-short pulse laser generation technique. The range of duration may vary from picoseconds to femtoseconds. Yttrium Oxide (Y2O3) based saturable absorber (SA) was appropriately revealed in the mode-locked method within 1.55-micron regime. Y2O3 perfect for strength, melting point, and chemical stability can be used as a laminated insulator due its properties. Moreover, also owns broadband service, switching speed, engineering features. Y2O3-PVA film produced by combining 50 mg powder into mL polyvinyl alcohol (PVA) solution stirring it at room temperature about 24 h. A recorded with integrated SA erbium-doped fiber (EDFL) cavity, output spectrum optical analyzer displayed around 1560.66 nm. In addition sustained pulse, nearly constant repetition rate 1.01 MHz specific pump power begins 175.87 mW 228.04 while 4.15 ps. Lastly, had been evaluated, which showed peak started 4.94 kW 6.07 kW.

Mode-locking of thulium-doped and Erbium-doped fiber lasers
This thesis reports work on passive mode-locking of thulium-doped and erbium-doped fiber ring lasers using the technique of polarization additive pulse mode-locking (PAPM). A self-starting, mode-locked Tm+3-doped fiber laser was demonstrated with 360 to 500 fsec pulses tunable from 1.8 to 1.9 pm, the largest tuning range demonstrated from a rare-earth doped fiber. This laser operated in the sol...
متن کاملPassive mode locking of ytterbium- and erbium-doped all-fiber lasers using graphene oxide saturable absorbers.
Broadband graphene oxide/PVA films were used as saturable absorbers (SAs) for mode locking erbium-doped fiber laser (EDFL) and ytterbium-doped fiber laser (YDFL) at 1.06 μm and 1.55 μm. They provide modulation depths of 3.15% and 6.2% for EDFL and YDFL, respectively. Stable self-starting mode-locked pulses are obtained for both lasers, confirming that the graphene oxide is cost-effective. We ha...

As in bulk amplifiers, the onset of nonlinear effects when amplifying ultra-short pulses in fiber amplifiers has been pointed out and investigated by several groups, specifically in erbium-doped fiber amplifiers ( EDFAs) [ l-3 1. Researchers have in fact used the Kerr nonlinearity in conjunction with group velocity dispersion in order to create even shorter pulses via higher-order soliton forma...

We demonstrate generation of sub-100 fs pulses at 1.5 µm in a mode-locked erbium-doped fiber laser using a 45°-tilted fiber grating element. The laser features a genuine all-fiber configuration. Based on the unique polarization properties of the 45°-tilted fiber grating, we managed to produce sub-100 fs laser pulses through proper dispersion management. To the best of our knowledge, this is the...
