Molao-motheo oa tokiso oaLaser ea semiconductor e ka fetoloang(Lezara e ka fetoloang)

Laser ea semiconductor e fetoloang ke mofuta oa laser e ka fetolang bolelele ba leqhubu la tlhahiso ea laser ka mokhoa o sa khaotseng sebakeng se itseng. Laser ea semiconductor e fetoloang e sebelisa tokiso ea mocheso, tokiso ea motlakase le tokiso ea mechini ho lokisa bolelele ba cavity, spectrum ea reflection ea grating, phase le li-variable tse ling ho fihlela tokiso ea bolelele ba leqhubu. Mofuta ona oa laser o na le mefuta e mengata ea lits'ebetso puisanong ea optical, spectroscopy, sensoring, bongaka le masimo a mang. Setšoantšo sa 1 se bontša sebopeho sa motheo salaser e ka fetoloang, ho kenyeletsoa yuniti ya ho fumana lesedi, mokoti wa FP o entsweng ka diipone tse ka pele le tse ka morao, le yuniti ya sefe ya kgetho ya mokgwa wa optical. Qetellong, ka ho fetola bolelele ba mokoti wa pontsho, sefe ya mokgwa wa optical e ka fihlella tlhahiso ya kgetho ya bolelele ba maqhubu.

Mokhoa oa ho lokisa le ho sibolloa ha oona

Molao-motheo oa ho lokisa oa ho lokisali-laser tsa semiconductorHaholo-holo ho itshetlehile ka ho fetola diparamente tsa mmele tsa resonator ya laser ho fihlella diphetoho tse tswelang pele kapa tse sa fellang ho bolelele ba leqhubu la laser e tswang. Diparamente tsena di kenyeletsa, empa ha di felle feela ho, index ya refractive, bolelele ba cavity, le kgetho ya mokgwa. Tse latelang di hlalosa mekgwa e mmalwa e tlwaelehileng ya ho lokisa le melaomotheo ya yona:

1. Ho lokisa ente ea kariki

Ho lokisa ka ente ea carrier ke ho fetola index ea refractive ea thepa ka ho fetola hona joale e kenngoeng sebakeng se sebetsang sa laser ea semiconductor, e le ho fihlella tokiso ea bolelele ba wavelength. Ha hona joale e eketseha, mahloriso a carrier sebakeng se sebetsang aa eketseha, e leng se fellang ka phetoho ho index ea refractive, e leng se amang bolelele ba wavelength ba laser.

2. Ho lokisa mocheso Ho lokisa mocheso ke ho fetola index ea refractive le bolelele ba sekoti sa thepa ka ho fetola mocheso o sebetsang oa laser, e le ho finyella ho lokisa bolelele ba wavelength. Liphetoho mochesong li ama index ea refractive le boholo ba 'mele ba thepa.

3. Ho lokisa ka mechine Ho lokisa ka mechine ke ho fihlella ho lokisa bolelele ba leqhubu ka ho fetola boemo kapa Sekhutlo sa likarolo tsa mahlo tsa kantle tsa laser. Mekhoa e tloaelehileng ea ho lokisa ka mechine e kenyelletsa ho fetola Sekhutlo sa grating ea diffraction le ho tsamaisa boemo ba seipone.

4 Ho lokisa ka motlakase Ho lokisa ka motlakase ho fihlellwa ka ho sebedisa tshimo ya motlakase ho thepa ya semiconductor ho fetola index ya refractive ya thepa, ka hona ho fihlella ho lokisa bolelele ba leqhubu. Mokgwa ona o sebediswa hangata holi-modulator tsa electro-optical (EOM) le li-laser tse lokisitsoeng ka motlakase.

Ka bokhutšoanyane, molao-motheo oa ho lokisa oa laser ea semiconductor e ka fetoloang haholo-holo o phethahatsa ho lokisa bolelele ba wavelength ka ho fetola liparamente tsa 'mele tsa resonator. Liparamente tsena li kenyelletsa index ea refractive, bolelele ba cavity, le khetho ea mokhoa. Mekhoa e ikhethileng ea ho lokisa e kenyelletsa ho lokisa ka ente ea carrier, ho lokisa mocheso, ho lokisa mechine le ho lokisa ka electro-optical. Mokhoa o mong le o mong o na le mokhoa oa oona o ikhethileng oa 'mele le ho tsoa ha lipalo, 'me khetho ea mokhoa o nepahetseng oa ho lokisa e hloka ho nahanoa ho latela litlhoko tse ikhethileng tsa ts'ebeliso, joalo ka sebaka sa ho lokisa, lebelo la ho lokisa, qeto le botsitso.
