Diode laser yog ib lub cuab yeej hluav taws xob uas siv PN junction nrog cov khoom siv binary lossis ternary semiconductor. Thaum lub zog hluav taws xob raug siv sab nraud, cov electrons hloov pauv los ntawm txoj kab conduction mus rau txoj kab valence thiab tso tawm lub zog, yog li tsim cov photons. Thaum cov photons no rov tshwm sim hauv PN junction, lawv yuav tawg tawm lub teeb laser muaj zog. Semiconductor lasers muaj cov yam ntxwv ntawm miniaturization thiab kev ntseeg siab siab, thiab lawv cov zaus laser tuaj yeem hloov kho los ntawm kev hloov pauv cov khoom siv, PN junction loj, thiab tswj voltage.
Cov diode lasers siv dav hauv cov teb xws li kev sib txuas lus fiber optic, optical discs, laser printers, laser scanners, laser indicators (laser pens), thiab lwm yam. Lawv yog cov laser loj tshaj plaws hauv kev tsim khoom. Tsis tas li ntawd, semiconductor lasers muaj ntau daim ntawv thov hauv laser ranging, LiDAR, kev sib txuas lus laser, laser simulation riam phom, laser ceeb toom, laser guidance thiab tracking, ignition thiab detonation, automatic control, detection instruments, thiab lwm yam, tsim kom muaj kev lag luam dav.
