20.500.12556/RUL-106041 Optimization of a supercontinuum source based on tapered ordinary fibers In this paper the generation of visible spectrum via optimized supercontinuum generation (SCG) in tapered ordinary fibers by ultrashort laser pulses is presented. The tunability of the visible part of the spectra is achieved by changing the pump pulse duration during operation. The optimization of the SCG is carried out by the investigation of the taper geometry with the emphasis on the downtapering section length. Its increase is found to be correlated to higher intensity in the visible part of the spectra. This is further supported by the results on spectra evolution before it enters the taper waist where an important transfer of the pump power to the shorter wavelengths is found. fiber lasers supercontinuum generation ytterbium-doped fiber amplifiers vlakenski laserji Iterbijeva vlakna tvorba supercontinuuma true false true Angleški jezik Slovenski jezik Članek v reviji 2019-01-18 13:35:30 2019-01-18 13:35:33 2025-02-24 13:48:59 0000-00-00 00:00:00 2019 0 0 Str. 1-6 nr. 2 Vol. 29 Jan. 2019 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2020-01-09 535:621.375.826(045) 1054-660X 10.1088/1555-6611/aaf640 16453659 RAZ_Cerne_Luka_i2019.pdf RAZ_Cerne_Luka_i2019.pdf 1 7143EAF138FDD63336DB987101C95115 8eaf285c85b00461ba5e274fb6bbb42b0707648c60a105a513a935edf6521afd 44b89c26-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116766 http://iopscience.iop.org/article/10.1088/1555-6611/aaf640/pdf 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116765 Fakulteta za strojništvo 0 0 0
