Kufambira mberi kwekutsvagamacolloidal quantum dot lasers
Zvichienderana nenzira dzakasiyana dzekupomba, ma colloidal quantum dot lasers anogona kukamurwa kuita mapoka maviri: ma optically pumped colloidal quantum dot lasers uye electrically pumped colloidal quantum dot lasers. Muminda yakawanda yakadai seye laboratori neindasitiri,ma laser anopombwa nemaziso, dzakadai semafiber lasers uye titanium-doped safira lasers, dziri kutamba basa rakakosha. Pamusoro pezvo, mune mamwe mamiriro chaiwo, akadai semumunda welaser yekufambisa kwechiedza che microflow, nzira ye laser yakavakirwa pakupomba kwe optical ndiyo sarudzo yakanakisisa. Zvisinei, tichifunga nezvekutakurwa kwayo uye kushandiswa kwakasiyana-siyana, kiyi yekushandiswa kwe colloidal quantum dot lasers ndeyekuwana laser output pasi pekupomba kwemagetsi. Zvisinei, kusvika pari zvino, colloidal quantum dot lasers inopomba nemagetsi haisati yawanikwa. Nokudaro, nekuziva kwe colloidal quantum dot lasers inopomba nemagetsi semutsetse mukuru, munyori anotanga akurukura nezvechisungo chikuru chekuwana colloidal quantum dot lasers inopinzwa nemagetsi, kureva kuti, kuziva colloidal quantum dot continuous wave optically pumped laser, uye ozoenderera mberi kune colloidal quantum dot optically pumped solution laser, iyo inogona kunge iri yekutanga kushanda mubhizinesi. Maumbirwo emuviri wechinyorwa chino anoratidzwa muMufananidzo 1.

Dambudziko riripo
Mukutsvaga kwe colloidal quantum dot laser, dambudziko guru riripo nderekuti ungawana sei colloidal quantum dot gain medium ine threshold yakaderera, high gain, long gain life uye high stability. Kunyangwe zvivakwa zvitsva nezvinhu zvakaita se nanosheets, giant quantum dots, gradient gradient quantum dots, uye perovskite quantum dots zvakashumwa, hapana kana quantum dot yakasimbiswa muma laboratories akawanda kuti iwane continuous wave optically pumped laser, izvo zvinoratidza kuti gain threshold uye stability yema quantum dots hazvisati zvakwana. Pamusoro pezvo, nekuda kwekushaikwa kwe united standards ye synthesis uye performance characterization yema quantum dots, gain performance reports yema quantum dots kubva kunyika dzakasiyana nemarabhoritari dzakasiyana zvikuru, uye repeatability haisi yakakwira, izvo zvinokanganisawo kukura kwema colloidal quantum dots ane high gain properties.

Parizvino, laser ye electropumped ye quantum dot haisati yawanikwa, zvichiratidza kuti kuchine matambudziko mu fizikisi yekutanga uye tsvakiridzo huru ye quantum dot.midziyo yelaser. Colloidal quantum dots (QDS) chinhu chitsva chinogona kugadziriswa nemhinduro, chinogona kutaurwa nezve electroinjection device structure ye organic light-emitting diodes (LEDs). Zvisinei, zvidzidzo zvechangobva kuitwa zvakaratidza kuti nyore nyore kudzokorora hakuna kukwana kuti tizive electroinjection colloidal quantum dot laser. Tichifunga nezvemusiyano uripo mu electronic structure uye processing mode pakati pe colloidal quantum dots nezvinhu zve organic, kugadzira nzira itsva dzekugadzirisa solution film dzakakodzera colloidal quantum dots nezvinhu zvine electron uye hole transport functions ndiyo chete nzira yekuwana electrolaser inokonzerwa ne quantum dots. Colloidal quantum dot system yakakura zvikuru ichiri cadmium colloidal quantum dots ine heavy metals. Tichifunga nezvekuchengetedzwa kwezvakatipoteredza uye njodzi dzehupenyu, idambudziko guru kugadzira zvinhu zvitsva zve colloidal quantum dot laser zvinogara kwenguva refu.

Mubasa remangwana, tsvakiridzo yema "quantum dot lasers" anopumirwa nechiedza uye ma "quantum dot lasers" anopumirwa nemagetsi anofanirwa kufambidzana uye kuita basa rakakosha zvakaenzana mukutsvagisa kwekutanga uye mashandisirwo anoshanda. Mukushandiswa kwe "colloidal quantum dot laser" kunoshanda, matambudziko mazhinji akajairika anofanira kugadziriswa nekukurumidza, uye kuti tinganyatsoongorora sei hunhu hwakasiyana uye mabasa e "colloidal quantum dot".
