Kupita patsogolo kwa kafukufukuma laser a colloidal quantum dot
Malinga ndi njira zosiyanasiyana zopopera, ma laser a colloidal quantum dot amatha kugawidwa m'magulu awiri: ma laser a colloidal quantum dot optically pumped ndi ma laser a colloidal quantum dot optically pumped. M'magawo ambiri monga labotale ndi mafakitale,ma laser opompedwa ndi kuwala, monga ma laser a fiber ndi ma laser a safiro okhala ndi titaniyamu, akuchita gawo lofunika kwambiri. Kuphatikiza apo, m'zochitika zinazake, monga m'munda walaser ya microflow yowala, njira ya laser yochokera pa kupompa kwa kuwala ndiyo chisankho chabwino kwambiri. Komabe, poganizira kusunthika ndi mitundu yosiyanasiyana ya ntchito, chinsinsi chogwiritsa ntchito ma laser a colloidal quantum dot ndikukwaniritsa kutulutsa kwa laser pansi pa kupompa kwamagetsi. Komabe, mpaka pano, ma laser a colloidal quantum dot opompedwa ndi magetsi sanakwaniritsidwe. Chifukwa chake, pozindikira ma laser a colloidal quantum dot opompedwa ndi magetsi ngati mzere waukulu, wolembayo choyamba akukambirana za ulalo wofunikira wopezera ma laser a colloidal quantum dot opompedwa ndi magetsi, ndiko kuti, kuzindikira kwa laser yopitilira ya colloidal quantum dot yopompedwa ndi magetsi, kenako ndikufikira ku laser yopitilira ya colloidal quantum dot opompedwa ndi magetsi, yomwe ingakhale yoyamba kugwiritsidwa ntchito pamalonda. Kapangidwe ka thupi ka nkhaniyi kakuwonetsedwa mu Chithunzi 1.

Vuto lomwe lilipo
Mu kafukufuku wa laser ya colloidal quantum dot, vuto lalikulu ndi momwe mungapezere colloidal quantum dot gain medium yokhala ndi threshold yotsika, high gain, long gain life komanso high stability. Ngakhale kuti mapangidwe atsopano ndi zipangizo monga nanosheets, giant quantum dots, gradient gradient quantum dots, ndi perovskite quantum dots zanenedwa, palibe quantum dot imodzi yomwe yatsimikiziridwa m'ma laboratories angapo kuti ipeze continuous wave optically pumped laser, zomwe zikusonyeza kuti gain threshold ndi stability ya quantum dots sizikukwanira. Kuphatikiza apo, chifukwa cha kusowa kwa miyezo yogwirizana ya kapangidwe ndi mawonekedwe a magwiridwe antchito a quantum dots, malipoti a gain performance a quantum dots ochokera kumayiko osiyanasiyana ndi ma laboratories amasiyana kwambiri, ndipo kubwerezabwereza sikokwera, komwe kumalepheretsanso chitukuko cha colloidal quantum dots okhala ndi katundu wokwera kwambiri.

Pakadali pano, laser yopompedwa ndi electropumped ya quantum dot sinakwaniritsidwe, zomwe zikusonyeza kuti pakadali zovuta mu fizikisi yoyambira ndi kafukufuku wofunikira wa ukadaulo wa quantum dot.zipangizo za laserMadontho a Colloidal quantum (QDS) ndi zinthu zatsopano zopezera mayankho zomwe zingathe kukonzedwa, zomwe zitha kutchulidwa ku kapangidwe ka chipangizo cha electroinjection cha ma diode otulutsa kuwala kwachilengedwe (ma LED). Komabe, kafukufuku waposachedwapa wasonyeza kuti kutchula kosavuta sikokwanira kuzindikira electroinjection colloidal quantum dot laser. Poganizira kusiyana kwa kapangidwe ka zamagetsi ndi njira yogwiritsira ntchito pakati pa madontho a colloidal quantum ndi zinthu zachilengedwe, kupanga njira zatsopano zokonzekera filimu yothetsera yankho yoyenera madontho a colloidal quantum ndi zinthu zomwe zili ndi ntchito zoyendera ma elekitironi ndi mabowo ndiyo njira yokhayo yopezera electrolaser yoyambitsidwa ndi madontho a quantum. Dongosolo la colloidal quantum dot lokhwima kwambiri likadali madontho a cadmium colloidal quantum okhala ndi zitsulo zolemera. Poganizira za chitetezo cha chilengedwe ndi zoopsa zamoyo, ndizovuta kwambiri kupanga zinthu zatsopano za colloidal quantum dot laser.

Mu ntchito zamtsogolo, kafukufuku wa ma laser a quantum dot opangidwa ndi kuwala ndi ma laser a quantum dot opangidwa ndi magetsi ayenera kugwirizana ndipo ayeneranso kukhala ndi gawo lofunikira kwambiri pa kafukufuku woyambira ndi ntchito zothandiza. Pakugwiritsa ntchito ma laser a colloidal quantum dot, mavuto ambiri ofala ayenera kuthetsedwa mwachangu, ndipo momwe angagwiritsire ntchito mokwanira mawonekedwe ndi ntchito zapadera za ma dot a colloidal quantum ziyenera kufufuzidwa.
