Amakuru yubushakashatsi buheruka bwo gutumanaho ikirere

Amakuru yubushakashatsi agezweho yaitumanaho ryumwanya

Sisitemu ya interineti ya satelite, hamwe nisi ikwirakwizwa kwisi yose, ubukererwe buke hamwe numuyoboro mwinshi, byahindutse icyerekezo cyingenzi cyiterambere ryiterambere ryikoranabuhanga. Umwanya wa laser itumanaho nubuhanga bwibanze mugutezimbere sisitemu yitumanaho.AmashanyaraziYerekana uburyo bushoboka bwo gukoresha mumashanyarazi ya sisitemu ya sisitemu bitewe nubushobozi bwayo buhanitse, ubuzima burebure, ubunini buto, uburemere bworoshye nibiranga modulisiyo nziza. Nyamara, imirasire yizuba yizuba, imirasire yumubumbe wa galaktike hamwe numubare munini wingufu zingufu nyinshi nka proton, electron na ion ziremereye mukenyero ka geomagnetic mukarere kahantu hashobora gutuma habaho kwangirika kwimikorere yibikoresho ndetse bikanatuma habaho gutsindwa kwibikoresho, bikabangamira cyane sisitemu yo gutumanaho ya laser.

Vuba aha, itsinda ry’ubushakashatsi mu Bushinwa ryateye intambwe igaragara mu bushakashatsi bwakozwe na kwant dot laseri mu itsinda ryitumanaho ryumwanya. Binyuze mu guhanga udushya twinshi hamwe no gukora neza mukarere, itsinda ryateje imbere ibisubizo byubushakashatsi buheruka bwo gutumanaho mu kirere, bifite imikorere myiza mu bidukikije bifite ingufu nyinshi, kwaduka kwaduka. Bakoze isesengura ryimbitse ryo kugereranya imikorere ya sisitemu zitandukanye mubidukikije. Ibisubizo byubushakashatsi byerekana ko imiterere ya kwant ya kwant yerekana ibyiza bidasanzwe byubaka muburyo bwiza bwingufu zingirakamaro zidukikije zo munsi yisi.

Ukurikije ubu buvumbuzi, itsinda ryubushakashatsi ryateguye neza kandi rihimba ubwoko bushya bwaQuant Dot laser. Igikoresho cyerekana imikorere myiza mubidukikije bikabije: kuri 3MeV inshinge ya proton igera kuri cm 7 × 1013 cm-2, laser ikomeza ibintu byongerera umurongo hafi ya zeru; Urusaku rugereranije ubukana bwurusaku (RIN) rwibikoresho ruri hasi ya -163 dB / Hz, ndetse no mubunini ntarengwa bwo gutera inshinge, RIN yiyongera kuri 1 dB / Hz gusa. Mubyongeyeho, laser irashobora gukora neza muburyo bukomeye bwo gutanga ibitekerezo bya -3.1dB. Ibi byagezweho ntabwo byemeza gusa ibisubizo byubushakashatsi buheruka bwo gutumanaho mu kirere, ariko kandi bitanga ibyiringiroigisubizo cyumucyoyo kubaka imiyoboro yo gutumanaho ikora cyane.
