摘要: A medium consisting of quartz with embedded active (amplifying) or passive (absorbing) impurities, i.e., quantum dots, is proposed for producing extremely short dissipative solitons on the basis effect enhanced self-induced transparency. The calculations show that, in such a medium, initial standard femtosecond pulses can be transformed into peak intensity ∼1011 W/sm2, duration corresponding to inverse frequency transitions and coherent spectral supercontinuum covering almost entire transmission region quartz.
