Kodi laser ya diode ndi chiyani?

Diode laser ndi chipangizo chamagetsi chomwe chimagwiritsa ntchito PN junction yokhala ndi zinthu za binary kapena ternary semiconductor. Voltage ikagwiritsidwa ntchito kunja, ma elekitironi amasamuka kuchoka pa conduction band kupita ku valence band ndikutulutsa mphamvu, motero amapanga ma photon. Ma photon awa akamaonekera mobwerezabwereza mu PN junction, amatuluka kuwala kwa laser kolimba. Ma semiconductor lasers ali ndi mawonekedwe a miniaturization komanso kudalirika kwakukulu, ndipo ma laser frequency awo amatha kusinthidwa posintha kapangidwe ka zinthu, kukula kwa PN junction, ndi control voltage.

Ma laser a diode amagwiritsidwa ntchito kwambiri m'magawo monga kulumikizana kwa fiber optic, ma disc optical, ma laser printers, ma laser scanners, ma laser indicators (ma laser pen), ndi zina zotero. Ndiwo laser yayikulu kwambiri pankhani ya kuchuluka kwa kupanga. Kuphatikiza apo, ma semiconductor lasers ali ndi ntchito zambiri mu laser, LiDAR, kulumikizana kwa laser, zida zoyeserera za laser, machenjezo a laser, chitsogozo cha laser ndi kutsatira, kuyatsa ndi kuphulika, kulamulira kodziyimira pawokha, zida zodziwira, ndi zina zotero, zomwe zimapangitsa msika waukulu.
