Nhau dzetsvagurudzo dzazvino dzenzvimbo yekukurukurirana laser
Satellite Internet system, ine kufukidzwa kwayo kwepasi rose, yakaderera latency uye yakakwirira bandwidth, yave nzira yakakosha yekuvandudza tekinoroji yekutaurirana. Space Laser kutaurirana ndiyo yakakosha tekinoroji mukuvandudza setiraiti yekutaurirana system.Semiconductor laserinoratidza yakafara application kugona mune space laser yekutaurirana system nekuda kwekushanda kwayo kwakanyanya, hupenyu hwakareba, saizi diki, huremu huremu uye yakanakisa modulation maitiro. Nekudaro, solar cosmic mwaranzi, galactic cosmic mwaranzi uye huwandu hukuru hwepamusoro-simba rinochaja zvimedu zvakaita seproton, maerekitironi uye inorema ion mugeomagnetic capture bhandi munzvimbo yechadenga zvinogona kukonzeresa kuderera kwekuita kwechishandiso uye kutotungamira mukukundikana kwechishandiso, izvo zvinotyisidzira zvakanyanya kuvimbika uye kugadzikana kwenzvimbo laser yekutaurirana masisitimu.
FIG1. Chimbo chekuedza chelaserkuongororwa kwekuita
Munguva pfupi yapfuura, timu yekutsvagisa muChina yakaita budiriro yakakosha mukutsvagisa kwekuita kwequantum dot lasers mubhendi rekutaurirana renzvimbo. Kuburikidza nekugadzira bhendi dhizaini uye inoshanda dunhu dhizaini, timu yakabudirira kuvandudza yazvino tsvagiridzo yenzvimbo yekutaurirana lasers, ine mashandiro akanaka kwazvo munzvimbo yepamusoro-simba particle nharaunda, quantum dot lasers. Vakaita ongororo yakadzama yekuenzanisa kwekuita kwemaitiro akasiyana ezvinhu munzvimbo yenzvimbo. Mhedzisiro yekuedza inoratidza kuti iyo quantum dot chimiro inoratidza zvinoshamisa kugadzikana kwemaitiro mabhenefiti munzvimbo yepamusoro-simba particle nharaunda yepasi pasi orbit.
Kubva pane zvakawanikwa izvi, boka rekutsvagisa rakabudirira kugadzira nekugadzira rudzi rutsva rwequantum dot laser. Chishandiso chinoratidza kuita kwakanakisa munzvimbo dzakanyanyisa: pa3MeV proton jekiseni kusvika ku7 × 1013 cm-2, iyo laser inochengetedza mutsara wekuwedzera chinhu chiri pedyo ne zero; Iyo inoreva hama intensity ruzha (RIN) yechishandiso yakaderera se -163 dB/Hz, kunyangwe pahupamhi hwejekiseni, iyo RIN inowedzera ne1 dB/Hz chete. Pamusoro pezvo, iyo laser inogona kushanda zvakatsiga pasi peiyo yakasimba mwenje mhinduro mamiriro e -3.1dB. Kubudirira uku hakungobvumire chete yazvino tsvakiridzo mhedzisiro yenzvimbo yekutaurirana lasers, asi zvakare inopa yakavimbikalight source solutionpakuvaka kwepamusoro-soro setiraiti yekutaurirana network.
