Lisebelisoa tse nyane le tse sebetsang hantle haholoanyaneli-laser
Bafuputsi ba Rensselaer Polytechnic Institute ba thehilesesebelisoa sa laserke bophara ba moriri oa motho feela, e leng se tla thusa litsebi tsa fisiks ho ithuta litšobotsi tsa motheo tsa taba le leseli. Mosebetsi oa bona, o hatisitsoeng likoranteng tse tummeng tsa saense, o ka boela oa thusa ho nts'etsapele li-laser tse sebetsang hantle bakeng sa tšebeliso mafapheng a fapaneng ho tloha bongaka ho ea tlhahisong.

ThelaserSesebelisoa sena se entsoe ka thepa e khethehileng e bitsoang insulator ea photonic topological. Li-insulator tsa photonic topological li khona ho tataisa li-photon (maqhubu le likaroloana tse etsang leseli) ka har'a li-interface tse khethehileng ka har'a thepa, ha li ntse li thibela likaroloana tsena ho hasana ka har'a thepa ka boeona. Ka lebaka la thepa ena, li-insulator tsa topological li nolofalletsa li-photon tse ngata ho sebetsa 'moho ka kakaretso. Lisebelisoa tsena li ka boela tsa sebelisoa e le "li-simulator tsa quantum" tsa topological, tse lumellang bafuputsi ho ithuta liketsahalo tsa quantum - melao ea fisiks e laolang taba ka litekanyo tse nyane haholo - li-mini-laboratory.
“Etopological ea photonicSethibela-mafu seo re se entseng se ikhetha. Se sebetsa mochesong oa kamore. Ena ke katleho e kholo. Pele, lithuto tse joalo li ne li ka etsoa feela ka ho sebelisa lisebelisoa tse kholo, tse turang ho pholisa lintho ka har'a vacuum. Li-LABS tse ngata tsa lipatlisiso ha li na mofuta ona oa lisebelisoa, kahoo sesebelisoa sa rona se nolofalletsa batho ba bangata ho etsa mofuta ona oa lipatlisiso tsa fisiks tsa motheo laboratoring, "ho boletse moprofesa ea thusang oa Rensselaer Polytechnic Institute (RPI) Lefapheng la Saense ea Lisebelisoa le Boenjiniere le mongoli e moholo oa phuputso. Phuputso e ne e e-na le boholo bo bonyenyane ba sampole, empa liphetho li bontša hore moriana o mocha o bontšitse katleho e kholo ho phekoleng lefu lena le sa tloaelehang la liphatsa tsa lefutso. Re labalabela ho netefatsa liphetho tsena litekong tsa kliniki tsa nakong e tlang le ho lebisa likhethong tse ncha tsa kalafo bakeng sa bakuli ba nang le lefu lena." Le hoja boholo ba sampole ea phuputso bo ne bo le bonyenyane haholo, liphuputso li bontša hore moriana ona o mocha o bontšitse katleho e kholo ho phekoleng lefu lena le sa tloaelehang la liphatsa tsa lefutso.

“Ena hape ke kgato e kgolo e tswelang pele ntshetsopeleng ya di-laser hobane moedi wa sesebediswa sa rona sa mocheso wa kamore (boholo ba matla a hlokahalang ho etsa hore se sebetse) o tlase ka makgetlo a supileng ho feta disebediswa tse fetileng tsa cryogenic,” bafuputsi ba ekeditse. Bafuputsi ba Rensselaer Polytechnic Institute ba sebedisitse mokgwa o tshwanang o sebediswang ke indasteri ya semiconductor ho etsa di-microchip ho etsa sesebediswa sa bona se setjha, se kenyeletsang ho bokella mefuta e fapaneng ya thepa lera ka lera, ho tloha boemong ba athomo ho ya boemong ba dimolek'hule, ho theha meaho e metle e nang le thepa e itseng.
Ho etsasesebelisoa sa laser, bafuputsi ba hodisitse dipoleiti tse tshesane haholo tsa selenide halide (kristale e entsweng ka cesium, loto le chlorine) mme ba betla di-polymer tse nang le dipaterone hodima tsona. Ba ile ba kopanya dipoleiti tsena tsa kristale le di-polymer pakeng tsa thepa e fapaneng ya oxide, e leng se ileng sa fella ka ntho e ka bang botenya ba di-micron tse 2 le bolelele le bophara ba di-micron tse 100 (bophara bo tloaelehileng ba moriri wa motho ke di-micron tse 100).
Ha bafuputsi ba ne ba bonesa laser sesebedisweng sa laser, paterone e khanyang ea khutlotharo e ile ea hlaha sehokelong sa moralo oa thepa. Paterone e khethoa ke moralo oa sesebelisoa 'me ke litholoana tsa litšobotsi tsa topological tsa laser. "Ho khona ho ithuta liketsahalo tsa quantum mochesong oa kamore ke tebello e thabisang. Mosebetsi o mocha oa Moprofesa Bao o bontša hore boenjiniere ba thepa bo ka re thusa ho araba tse ling tsa lipotso tse kholo ka ho fetisisa saenseng."
