Lisebelisoa tse nyane le tse sebetsang haholoanyanelisebelisoa tsa laser
Bafuputsi ba Rensselaer Polytechnic Institute ba thehile asesebelisoa sa laserhoo ke bophara feela ba moriri oa motho, o tla thusa litsebi tsa fisiks ho ithuta lintho tsa motheo tsa taba le leseli. Mosebetsi oa bona, o hatisitsoeng likoranteng tse tumileng tsa mahlale, le ona o ka thusa ho hlahisa lisebelisoa tsa laser tse sebetsang hantle haholoanyane bakeng sa ho sebelisoa mafapheng a ho tloha ho tsa bongaka ho isa ho a tlhahiso.

Thelasersesebelisoa se entsoe ka thepa e khethehileng e bitsoang photonic topological insulator. Li-insulators tsa photonic topological li khona ho tataisa li-photon (maqhubu le likaroloana tse etsang leseli) ka li-interfaces tse khethehileng ka hare ho thepa, ha li ntse li thibela likaroloana tsena ho hasana ka thepa ka boeona. Ka lebaka la thepa ena, li-insulators tsa topological li nolofalletsa li-photon tse ngata ho sebetsa hammoho ka kakaretso. Lisebelisoa tsena li ka boela tsa sebelisoa e le "quantum simulators" ea topological, e lumellang bafuputsi ho ithuta quantum phenomena - melao ea tlhaho e laolang taba ka litekanyo tse nyane haholo - li-mini-labs.
“Thephotonic topologicalinsulator eo re e entseng e ikhethile. E sebetsa ka mocheso oa kamore. Ena ke khatelo-pele e kholo. Nakong e fetileng, lithuto tse joalo li ne li ka etsoa feela ka lisebelisoa tse kholo, tse turang ho pholisa lintho ka har'a vacuum. Li-LABS tse ngata tsa lipatlisiso ha li na lisebelisoa tsa mofuta ona, ka hona sesebelisoa sa rona se thusa batho ba bangata ho etsa lipatlisiso tsa mofuta ona tsa fisiks ka laboratoring, "ho boletse motlatsi oa motlatsi oa Rensselaer Polytechnic Institute (RPI) Lefapheng la Mahlale a Materials le Boenjiniere. sengoli sa thuto. Boithuto bona bo ne bo e-na le sampole e nyane haholo, empa liphetho li fana ka maikutlo a hore sethethefatsi se secha se bontšitse katleho e kholo ho phekoleng lefu lena le sa tloaelehang la lefutso.

"Ena hape ke mohato o moholo oa tsoelo-pele ea lasers hobane moeli oa mochine oa mocheso oa kamore ea rona (tekanyo ea matla a hlokahalang ho etsa hore e sebetse) e fokotsehile ka makhetlo a supileng ho feta lisebelisoa tse fetileng tsa cryogenic," bafuputsi ba phaella ka ho re. Bafuputsi ba Rensselaer Polytechnic Institute ba sebelisitse mokhoa o ts'oanang o sebelisoang ke indasteri ea semiconductor ho etsa li-microchips ho theha sesebelisoa sa bona se secha, se kenyelletsang ho bokella mefuta e fapaneng ea lisebelisoa ka lera, ho tloha ho athomo ho isa boemong ba limolek'hule, ho theha meaho e metle e nang le thepa e ikhethang.
Ho etsa horelisebelisoa tsa laser, bafuputsi ba ile ba hōlisa lipoleiti tse tšesaane haholo tsa selenide halide (kristale e entsoeng ka cesium, loto le chlorine) 'me ba kenya li-polymers tse nang le mohlala ho tsona. Ba ile ba kopanya lipoleiti tsena tsa kristale le li-polymers pakeng tsa lisebelisoa tse sa tšoaneng tsa oxide, ho fella ka ntho e ka bang 2 microns e teteaneng le 100 microns bolelele le bophara (bophara bo tloaelehileng ba moriri oa motho ke 100 microns).
