High Performance Vcsel Laser Diode 3535 Quartz iav Lens 840-850nm

Ib lub laser diode (LD, kuj txhaj tshuaj laser diode los yog ILD, los yog diode laser) yog ib tug semiconductor ntaus ntawv zoo ib yam li lub teeb-emitting diode nyob rau hauv uas ib tug diode pumped ncaj qha nrog hluav taws xob tam sim no yuav tsim lasing tej yam kev mob ntawm lub diode txoj kev sib tshuam. Tsav los ntawm qhov hluav taws xob, qhov doped p-n-kev hloov pauv tso cai rau kev sib txuas ntawm ib qho hluav taws xob nrog lub qhov. Vim qhov poob ntawm cov hluav taws xob los ntawm qib siab zog mus rau qis dua, hluav taws xob, nyob rau hauv daim ntawv ntawm photon emitted yog generated. Qhov no yog spontaneous emission. Stimulated emission tuaj yeem tsim tau thaum cov txheej txheem txuas ntxiv thiab txuas ntxiv tsim lub teeb nrog tib theem, coherence thiab wavelength. Kev xaiv ntawm cov khoom siv semiconductor txiav txim siab lub wavelength ntawm lub emission beam, uas nyob rau hauv niaj hnub laser diodes muaj xws li infrared mus rau UV spectrum. Laser diodes yog hom lasers feem ntau tsim, nrog ntau yam kev siv uas suav nrog kev sib txuas lus fiber ntau optic, nyeem ntawv barcode, laser pointers, CD / DVD / Blu-duab tshav disc nyeem / kaw, laser luam ntawv, laser scanning thiab lub teeb beam illumination. . Nrog kev siv cov phosphor zoo li uas pom ntawm cov LEDs dawb, laser diodes tuaj yeem siv rau kev teeb pom kev dav dav.
