Semiconductor lasers laser diodes yog li Crystal lasers nrog cov ntaub ntawv khoom siv hluav taws xob. Vim yog qhov sib txawv hauv cov qauv ntawm cov teeb meem, cov khoom sib txawv ntawm cov txheej txheem laser yog qhov tshwj xeeb. Feem ntau siv cov khoom ua haujlwm gallium arsenide (GaAs), cadmium sulfide (CdS), indium phosphide (InP), zinc sulfide (ZnS). Kev kub siab ua suav nrog electrolysis, hluav taws xob nqaj excitation thiab kev siv qhov muag pom muaj peb hom. Semiconductor Laser cov cuab yeej, tuaj yeem muab faib ua tib lub pob, tib qho kev hloov pauv ntawm ob tog qhov qub teeb meem, thiab lwm yam. Homojunction laser thiab ib-heterojunction lasers ntawm chav tsev kub rau pulsed pab kiag li lawm, thiab lub ob heterostructure lasers ntawm chav tsev kub enables mus ua hauj lwm.
Semiconductor diode laser yog qhov ua tau zoo tshaj plaws thiab tseem ceeb tshaj plaws lasers. Nws qhov loj me me, lub neej ntev, thiab cov hom yooj yim tam sim no tuaj yeem siv los txhaws nws qhov kev ua haujlwm voltage thiab tam sim no yog sib xws nrog ICS, yog li nrog monolithic kev sib xyaw. Thiab koj tseem tuaj yeem siv cov kev hloov kho tam sim no ncaj qha mus txog GHz zaus kom tau txais qhov siab ceev cov teeb meem ntawm cov zis laser. Vim tias cov kev zoo no, lub semiconductor diode laser hauv kev sib txuas lus kho qhov muag, chaw cia khoom kho qhov muag, kho qhov muag kho qhov muag, laser luam tawm, ntu thiab radar, ntxiv rau nkag mus rau ntau cov ntawv thov.
