20.500.12556/RUL-105560 DFB diode seeded low repetition rate fiber laser system operating in burst mode A distributed feedback (DFB) diode, gain switched to produce pulses from 60 ps at high peak power of over 0.5 W, is used in burst mode to seed a fiber amplifier chain. High seed power, spectral filtering between amplifier stages and pulsed pumping are used to mitigate amplified spontaneous emission (ASE). The effect of pulse pumping synchronized with the seed on the ASE is explored for the power amplifier at low repetition. Different input and output energies at different burst repetition rates are examined and up to 85% reduction in ASE is achieved compared to continuous pumping. Finally, a numerical model is used to predict further reduction of ASE. fiber lasers laser amplifiers ytterbium fibers vlakenski laserji laserski ojačevalniki iterbijeva vlakna true false true Angleški jezik Slovenski jezik Članek v reviji 2018-12-06 08:09:58 2018-12-06 08:09:59 2025-02-24 11:42:29 0000-00-00 00:00:00 2017 0 0 Str. 99-103 Vol. 88 Feb. 2017 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2018-09-15 535(045) 0030-3992 10.1016/j.optlastec.2016.09.006 14904091 26072576 RAZ_Sajn_Marko_i2017.pdf RAZ_Sajn_Marko_i2017.pdf 1 E31DAB8EBBED48FE2DACA2CABDB71E34 5f0a26f33eee77fb07356ffa74c66f865a5ddf0303204bb9f94821e020719c3c 334e8f27-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116235 http://www.sciencedirect.com/science/article/pii/S0030399216306247 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=116234 Fakulteta za strojništvo 0 0 0
