Kodi diode laser ndi chiyani?

Diode laser ndi chipangizo chamagetsi chomwe chimagwiritsa ntchito mphambano ya PN yokhala ndi zida za binary kapena ternary semiconductor. Mphamvu yamagetsi ikagwiritsidwa ntchito kunja, ma elekitironi amasintha kuchokera ku bandi yoyendetsa kupita ku gulu la valence ndikutulutsa mphamvu, potero kupanga mafotoni. Pamene ma photon awa akuwonetsera mobwerezabwereza mu mphambano ya PN, amaphulika kuwala kwamphamvu kwa laser. Ma laser a semiconductor ali ndi mawonekedwe a miniaturization komanso kudalirika kwakukulu, ndipo ma frequency awo a laser amatha kusinthidwa posintha kapangidwe kazinthu, kukula kwa makulidwe a PN, ndi magetsi owongolera.

Ma lasers a diode amagwiritsidwa ntchito kwambiri m'magawo monga kuyankhulana kwa fiber optic, ma discs optical, osindikiza laser, makina ojambulira laser, zizindikiro za laser (zolembera za laser), ndi zina zotero. Kuphatikiza apo, ma semiconductor lasers ali ndi ntchito zambiri zama laser kuyambira, LiDAR, kulumikizana kwa laser, zida zoyeserera za laser, chenjezo la laser, kuwongolera kwa laser ndi kutsatira, kuyatsa ndi kuphulika, kuwongolera zokha, zida zodziwira, ndi zina zambiri, kupanga msika waukulu.
