Ubuchwepheshe obuhlangene obuhlanganisayo be-ultrashort pulse

Ngamandla aphezulu we-ultrashort pulse laser, inikela ngamavelu amahle ocwaningweni lwesayensi, ukukhiqizwa kwezimboni kanye nenkundla yezokwelapha.Isistimu evamile yobuchwepheshe obuhlangene obuhlanganisayo be-ultrashort pulse iboniswa njengomfanekiso 1.

                                                           Umdwebo 1 Izindlela zokuhlanganisa/zokuhlukanisa

I-Laser imbewu ye-pulse izohlukaniswa ibe yi-pulse eminingana, khona-ke amandla ayo azokhuliswa yi-AMP, wonke ukushaya kwe-pulse kuzohlangana kube okukodwa ukuze kukhuphuke amandla okushaya kwe-pulse namandla.Ukuze ugweme umphumela ongaqondile, ubuchwepheshe be-CPA buzosetshenziswa ekwandiseni imbewu ye-laser ishayela kuqala ukuze kukhuliswe amandla, bese kucindezela ububanzi be-pulse.Kunezindlela ezintathu zokufinyelela ukuhlanganisa okuhambisanayo kwe-ultrashort pulse: ukuhlanganisa okuhambisana kwendawo, ukukhulisa i-pulse (DPA), kanye ne-pulse stack.

Ngokuphathelene nokuhlanganisa indawo okuhambisanayo(umfanekiso 1(a)), ubuchwepheshe obuyisisekelo bufana nelaser eqhubekayo.Imbewu ye-Laser ihlukaniswa nge-splitter, ukuhlukaniswa ngakunye kukhuliswa yi-modulator yesigaba kanye ne-amplifier yamandla futhi ekugcineni ihlanganiswe njengokuhlanganiswa okukodwa.

Indlela yesibili i-DPA(umfanekiso 1(b)) ehlukanisa i-laser pulse ngokulandelana kwe-laser ngayinye ehlukene futhi engathintwa enye nenye.Lokhu kulandelana kwe-laser kuzohlangana kube yi-laser pulse ukuze kukhuphuke amandla aphezulu okukhipha i-pulse.

I-Pulse stack(umdwebo 1(c)) ingenza ama-pulse amaningi anqwabelene abe yi-pulse eyodwa engazuzwa nge-GTI kanye ne-SND(isitaki-nokulahla).

Cishe ngaso leso sikhathi lapho kwasungulwa ubuchwepheshe obuhlanganisayo namalaser, athole impumelelo ebalulekile ekuhlanganiseni kwe-fiber laser esheshayo engu-10.3kw kanye neziteshi ezinkulu eziyi-100 zokuhlanganisa i-fiber laser ehlangene, futhi kwaqaphela ukubaluleka kwayo ekuguquleni imvamisa ye-laser, laser radar kanye laser guide star.Ukuthuthukiswa kobuchwepheshe obuqhubekayo bama-lasers kunikeza umthombo wokukhanya omusha ukuze kuhlanganiswe okuhambisanayo, ngokubuyisela, ukukhanya okukhulayo komthombo wokukhanya kuncike ekuhlanganiseni ubuchwepheshe obuhambisanayo.
