Yuav ua li cas Yog Diode Laser

Semiconductor lasers, tseem hu ua laser diodes, yog cov lasers uas siv cov khoom siv semiconductor ua cov ntaub ntawv ua haujlwm. Vim tias qhov sib txawv ntawm cov khoom qauv, cov txheej txheem tshwj xeeb ntawm laser tiam ntawm ntau hom yog tshwj xeeb. Cov tshuaj yeeb dej caw uas siv hauv kev ua haujlwm muaj xws li gallium arsenide (GaAs), cadmium sulfide (CdS), indium phosphate (InP), thiab zinc sulfide (ZnS). Cov txheej txheem ua kom suav nrog kev txhaj tshuaj hluav taws xob, hluav taws xob teeb tsa hluav taws xob thiab lub tshuab nqus hluav taws xob. Lub tshuab hluav taws xob semiconductor muaj peev xwm muab faib ua hom phiaj ntawm cov pob zeb me me, cov pob zeb monomorphic pob, thiab kev sib txuam. Lasers lub tsev thiab cov monoheterojunction lasers feem ntau yog cov cuab yeej pulse ntawm chav sov, thaum ob chav Heterojunction lasers tuaj yeem ua haujlwm tsis tu ncua ntawm chav sov.
Lub semiconductor diode laser yog qhov siv tau thiab hom tseem ceeb tshaj plaws ntawm laser. Nws yog qhov me me ntawm qhov loj thiab ntev hauv lub neej, thiab tuaj yeem nqus tau nrog txoj kev txhaj tshuaj yooj yim tam sim no los txhawm rau nws qhov kev ua haujlwm voltage thiab tam sim no sib xyaw nrog kev sib txuam, yog li nws tuaj yeem ua ke nrog ib nti. Thiab koj tseem tuaj yeem siv cov zaus mus txog GHz los ncaj qha hloov kho tam sim no kom tau txais kev kub ceev.Thiab ... Vim tias cov kev zoo no, semiconductor diode lasers tau siv dav hauv kev sib txuas lus laser, chaw cia khoom kho qhov muag, kho qhov muag kho qhov muag, laser luam tawm, ntu thiab radar.
