I-femtosecond laser ngumthombo wokukhanya osezingeni eliphakeme eletha ama-laser pulses amafushane, imvamisa ngokulandelana kwemizuzwana eyi-10-15. Lobu buchwepheshe bokuqhubeka busebenzisa ukugcina okungekho emgqeni we-fiber loop, kuhlanganiswe ne-Yb enezinto eziphakeme zokugcina i-fiber amplifier, ukukhiqiza ukukhishwa kwe-laser okuzinzile futhi okuqondile.
