Kugenzura inshuro ya tekinoroji ya tekinoroji ya laser

Kugenzura inshuro nyinshitekinoroji yo kugenzura laser

1. Umuvuduko mwinshi wa pulses ukwiranye nigipimo cyinshi cyo gusubiramo, mugihe impiswi nkeya ikwiranye ningufu nyinshi zingirakamaro.

2. Isano iri hagati yimbaraga, ubugari bwimisemburo ninshuro Mbere yo kugenzura laser frequency, isano iri hagati yimbaraga, ubugari bwa pulse na frequency igomba kubanza gusobanurwa. Hariho imikoranire igoye hagati ya laser power, frequency and pulse ubugari, no guhindura kimwe mubipimo mubisanzwe bisaba gusuzuma ibindi bipimo bibiri kugirango uhindure ingaruka zo gusaba.

3. Uburyo busanzwe bwo kugenzura impanuka

a. Uburyo bwo kugenzura hanze butwara ibimenyetso byinshyi hanze yumuriro w'amashanyarazi, kandi bigahindura laser pulse inshuro mugucunga inshuro ninshingano byikimenyetso cyo gupakira. Ibi bituma ibisohoka bisohora guhuza hamwe nikimenyetso cyumutwaro, bigatuma gikoreshwa mubisabwa bisaba kugenzura neza.

b. Uburyo bwo kugenzura imbere Imbere Ikimenyetso cyo kugenzura cyubatswe mumashanyarazi atangwa, nta kimenyetso cyongeyeho cyo hanze. Abakoresha barashobora guhitamo hagati yimikorere yashizwemo cyangwa igenzurwa ryimbere mugihe cyo guhinduka.

c. Guhindura uburebure bwa resonator cyangwaamashanyarazi ya optiqueInshuro ziranga lazeri zirashobora guhinduka muguhindura uburebure bwa resonator cyangwa ukoresheje moderi ya electro-optique. Ubu buryo bwo kugenzura inshuro nyinshi bukoreshwa mubisabwa bisaba imbaraga zingana zingana nubugari bugufi bwa pulse, nka laser micromachining hamwe nubuvuzi bwubuvuzi.

d. Acousto optic Modulator(AOM Modulator) nigikoresho cyingenzi cyo kugenzura impanuka ya tekinoroji ya tekinoroji ya laser.Moderi ya AOMikoresha ingaruka za acousto optique (ni ukuvuga, umuvuduko wa tekinike yumuvuduko wijwi ryamajwi uhindura indangagaciro) kugirango uhindure kandi ugenzure urumuri rwa laser.

4.laser pulse. Ibikurikira nuburyo bune busanzwe bwo guhinduranya:

a. Kunguka Guhindura muguhindura byihuse isoko ya pompe, inyungu zingana zingana zingana no guhinduranya coefficient zashyizweho byihuse, zikarenga umuvuduko ukabije wimishwarara, bikaviramo kwiyongera gukabije kwa fotone mumyanya no kubyara lazeri ngufi. Ubu buryo bukunze kugaragara cyane muri lazeri ya semiconductor, ishobora kubyara impiswi kuva nanosekond kugeza kuri picosekondi icumi, hamwe nigipimo cyo gusubiramo gigahertz nyinshi, kandi ikoreshwa cyane mubijyanye n’itumanaho rya optique hamwe n’igipimo kinini cyo kohereza amakuru.

Q ihinduranya (Q-guhinduranya) Q ihindura ibitekerezo bya optique mugutangiza igihombo kinini mumyanya ya laser, bigatuma inzira yo kuvoma itanga umusaruro wabaturage bahindutse kurenga kurenga, babika ingufu nyinshi. Ibikurikiraho, igihombo kiri mu kavuyo kiragabanuka vuba (ni ukuvuga, Q agaciro k’urwobo kiyongereye), kandi ibitekerezo bya optique byongeye gufungura, ku buryo ingufu zabitswe zirekurwa mu buryo bwa ultra-short-high-strength pulses.

c. Mode Gufunga ibyara ultra-bigufi pulses ya picosekond cyangwa se urwego rwa femtosekond mugucunga isano yicyiciro hagati yuburyo butandukanye burebure mumyanya ya laser. Tekinoroji yo gufunga uburyo igabanijwemo uburyo bwo gufunga no gukora uburyo bwo gufunga.

d. Kujugunya Cavity Kubika ingufu muri fotone muri resonator, ukoresheje indorerwamo ya cavity yatakaye kugirango uhuze neza fotone, ukomeza gutakaza igihombo gito mumyanya mugihe runaka. Nyuma yuruzinduko rumwe, uruziga rukomeye "rujugunywa" mu mwobo uhindura byihuse ibintu byimbere munda, nka moderi ya acousto-optique cyangwa amashanyarazi ya electro-optique, hanyuma hasohoka lazeri ngufi. Ugereranije na Q-guhinduranya, gusiba cavity birashobora kugumana ubugari bwa pulse ya nanosekonds nyinshi ku gipimo cyo gusubiramo cyane (nka megahertz nyinshi) kandi ikemerera ingufu za pulse nyinshi, cyane cyane kubisabwa bisaba umuvuduko mwinshi wo gusubiramo hamwe na pulses ngufi. Ufatanije nubundi buryo bwo kubyara impiswi, ingufu za pulse zirashobora kurushaho kunozwa.

Kugenzura impanukalaserni inzira igoye kandi yingenzi, ikubiyemo kugenzura ubugari bwimisemburo, kugenzura inshuro nyinshi hamwe nubuhanga bwinshi bwo guhindura. Binyuze mu guhitamo gushyira mu gaciro no gukoresha ubu buryo, imikorere ya laser irashobora guhindurwa neza kugirango ihuze ibikenewe bitandukanye. Mu bihe biri imbere, hamwe no gukomeza kugaragara kw'ibikoresho bishya n'ikoranabuhanga rishya, tekinoroji yo kugenzura impiswi ya laseri izatangiza byinshi, kandi iteze imbere iteramberetekinoroji ya lasermu cyerekezo cyo hejuru cyane kandi cyagutse.
