Ezinhlelweni zesimanje ze-laser, ikhwalithi ye-beam isiphenduke enye yamamethrikhi abaluleke kakhulu okuhlola ukusebenza kukonke kwe-laser. Noma ngabe's ukusika ukunemba kweleveli ye-micron ekukhiqizeni noma ukutholwa kwebanga elide ngokulinganisa nge-laser, ikhwalithi ye-beam ngokuvamile inquma impumelelo noma ukwehluleka kohlelo lokusebenza.
Ngakho-ke, iyini ngempela ikhwalithi ye-beam? Ikuthinta kanjani ukusebenza kwe-laser? Futhi umuntu angayikhetha kanjani ikhwalithi ye-beam efanele ukufanisa nezidingo ezithile zohlelo lokusebenza?
1. Iyini i-Beam Quality?
Kalula nje, ikhwalithi ye-beam ibhekisela ezicini zokusakazeka kwendawo ze-laser beam. Ichaza indlela ugongolo olungagxila kahle ngayo, ukuziphatha kwalo kokuhlukana, nokuthi amandla alo asakazwa ngokufana kanjani.
Esimeni esihle, i-laser beam ifana ne-Gaussian efanelekile, efaka i-engeli encane yokuhluka nokusebenza okuhle kakhulu kokugxila. Kodwa-ke, ngenxa yezinto ezifana nesakhiwo somthombo, izakhiwo zezinto ezibonakalayo, nemiphumela yokushisa, imishayo ye-laser yomhlaba wangempela ivamise ukuhlushwa ukusabalala, ukuhlanekezelwa, noma ukuphazamiseka kwe-multimode.-ngaleyo ndlela kunciphisa ikhwalithi ye-beam.
2. Common Beam Quality Izinkomba
①M² I-Factor (I-Beam Propagation Factor)
I-M² inani ipharamitha eyinhloko esetshenziselwa ukuhlola ikhwalithi ye-beam.
M² = 1 ikhombisa ugongolo lwe-Gaussian oluphelele.
M² > 1 kusho ikhwalithi ye-beam iyona, futhi nekhono lokugxila liba libi.
Kuzicelo zezimboni, uM² amanani angaphansi kuka-1.5 ngokuvamile ayadingeka, kuyilapho amalaser ebanga lesayensi ahlose i-M² amanani asondele ku-1 ngangokunokwenzeka.
②I-Beam Divergence
Ukwehlukana kwe-beam kuchaza ukuthi inweba kangakanani i-laser beam njengoba ibhebhetheka ebangeni elide.
Ama-engeli amancane okuhlukana asho imishayo egxile kakhulu, izindawo ezincane okugxilwe kuzo, kanye nokunemba okukhulu kumabanga amade.
③Iphrofayela ye-Beam kanye Nokusabalalisa Amandla
I-beam yekhwalithi ephezulu kufanele ibe nephrofayili ye-symmetric, i-uniform ye-beam enesikhungo esiphezulu. Lokhu kuqinisekisa ukuphuma kwamandla acacile futhi alawulekayo wokusika, ukumakwa, nezinye izinhlelo zokusebenza.
3. Ikhwalithi ye-Beam Ithinta Kanjani Izicelo Zomhlaba Wangempela
①Ukucubungula Okunembayo (Ukusika/Ukushisela/Ukumaka):
Ikhwalithi yohlaka inquma usayizi wendawo okugxilwe kuyo kanye nokuminyana kwamandla, kube nomthelela ekunembeni komshini nokusebenza kahle.
②Ama-Laser ezokwelapha:
Ikhwalithi ye-beam ithinta ukuthi amandla alethwa ngokunembe kangakanani esicutshini kanye nendlela ukusabalalisa okushisayo kulawulwa kahle ngayo.
③Ububanzi be-Laser / LIDAR:
Ikhwalithi yohlaka ithonya ngokuqondile ububanzi bokutholwa nokulungiswa kwendawo.
④Ukuxhumana kwamehlo:
Ikhwalithi ye-beam ithinta ukuhlanzeka kwemodi yesiginali kanye nomthamo womkhawulokudonsa.
⑤Ucwaningo Lwesayensi:
Ikhwalithi ye-Beam iqinisekisa ukuhambisana nokuzinza ekuphazamiseni noma ekuhlolweni kokubona okungaqondile.
4. Izici Eziyinhloko Ezithinta Ikhwalithi Ye-Beam
①I-Laser Structure Design:
Ama-laser emodi eyodwa ngokuvamile ahlinzeka ngekhwalithi engcono ye-beam kunama-laser anemodi eminingi.
②Zuza Idizayini Ye-Medium & Resonator:
Lokhu kuthonya ukusabalalisa kwemodi nokuzinza kwe-beam.
③Ukuphathwa Kwe-Thermal Effect:
Ukushisa okungalungile kungaholela ekukhanyeni kwe-thermal kanye nokuhlanekezeka kwe-beam.
④Ukufana Kwephampu Nesakhiwo Se-Waveguide:
Ukupompa okungalingani noma ukukhubazeka kwesakhiwo kungabangela ukuwohloka komumo we-beam.
5. Indlela Yokuthuthukisa Ikhwalithi Ye-Beam
①Lungiselela Isakhiwo Sedivayisi:
Sebenzisa amagagasi emodi eyodwa kanye nemiklamo ye-symmetric resonator.
②Ukuphatha Okushisayo:
Hlanganisa amasinki okushisa asebenza kahle noma ukupholisa okusebenzayo ukuze unciphise ukuhlanekezela kwebhiliyamu okubangelwa ukushisa.
③I-Beam-Shaping Optics:
Sebenzisa ama-collimator, izihlungi zendawo, noma iziguquli zemodi.
④Ukulawulwa Kwedijithali Nempendulo:
Sebenzisa ukutholwa kwe-wavefront yesikhathi sangempela kanye nama-optics aguquguqukayo ukuze uzuze ukulungiswa okunamandla.
6. Isiphetho
Ikhwalithi ye-Beam ingaphezu nje kwepharamitha ephathekayo-it's kwe“ikhodi enembile”kwe-laser's ukusebenza.
Kuzinhlelo zokusebenza zomhlaba wangempela, ikhwalithi ephezulu ye-beam ingathuthukisa kakhulu ukusebenza kahle, ukunemba, nokuthembeka kwezinhlelo ze-laser. Kubasebenzisi abafuna ukusebenza okuphezulu nokungaguquguquki, ikhwalithi ye-beam kufanele icatshangwe lapho kukhethwa i-laser.
Njengoba ubuchwepheshe be-laser buqhubeka nokuvela, singalindela ukulawulwa okungcono kwe-beam kumadivayisi amancane nokuminyana kwamandla aphezulu-ukuvula indlela yamathuba amasha ekukhiqizeni okuthuthukisiwe, imithi enembayo, i-aerospace, nangale kwalokho.
