Ziyini i-Ultrafast Lasers futhi Zisetshenziswa Kanjani?

Incazelo yama-Ultrafast Lasers

Ama-laser asheshayo abhekisela kuma-laser akhipha ama-pulse amafushane kakhulu, ngokuvamile ebangeni le-picosecond (imizuzwana eyi-10⁻¹²) noma i-femtosecond (imizuzwana eyi-10⁻¹⁵). Ngenxa yobude bawo be-pulse obufushane kakhulu, lawa ma-laser asebenzisana nezinto ngokuyinhloko ngemiphumela engashisi, engeyona eye-linear, enciphisa kakhulu ukusabalala kokushisa kanye nomonakalo wokushisa. Lesi sici esiyingqayizivele senza ama-laser asheshayo afanelekele ukusebenza kahle kwe-micromachining, izinqubo zezokwelapha, kanye nocwaningo lwesayensi.

Ukusetshenziswa kwe-Ultrafast Lasers

Ngenxa yamandla awo aphezulu kanye nomthelela omncane wokushisa, ama-laser e-ultrafast asetshenziswa kabanzi emikhakheni eyahlukahlukene, okuhlanganisa:

1. I-Industrial Micromachining: Ama-laser ashesha kakhulu avumela ukusika, ukubhoboza, ukumaka, kanye nokucubungula ubuso ngokunembile emazingeni amancane namakhulu anezindawo ezincane ezithinteke kakhulu ekushiseni.

2. Ukuthwebula Izithombe Kwezokwelapha Nezokwelapha: Ku-ophthalmology, ama-laser e-femtosecond asetshenziselwa ukuhlinzwa kwamehlo kwe-LASIK, okunikeza ukusika okunembile kwe-cornea kanye nezinkinga ezincane ngemva kokuhlinzwa. Ngaphezu kwalokho, asetshenziswa ekuhlolweni kwe-multiphoton microscopy kanye nokuhlaziywa kwezicubu ze-biomedical.

3. Ucwaningo Lwesayensi: Lawa ma-laser adlala indima ebalulekile ku-spectroscopy exazululwe ngesikhathi, i-nonlinear optics, i-quantum control, kanye nocwaningo lwezinto ezintsha, okuvumela ososayensi ukuthi bahlole i-dynamics esheshayo emazingeni e-athomu kanye nama-molecule.

4. Ukuxhumana Okubonakalayo: Ama-laser athile ashesha kakhulu, njenge-laser yefayibha engu-1.5μm, asebenza ebhendini yokuxhumana yefayibha ekhanyayo elahlekelwa kancane, esebenza njengemithombo yokukhanya ezinzile yokudlulisa idatha ngesivinini esikhulu.

Amapharamitha Amandla Nokusebenza

Ama-laser e-Ultrafast abonakala ngamapharamitha amabili abalulekile wamandla:

1. Amandla Aphakathi: Asukela kumashumi ama-milliwatts kuya kuma-watts amaningana noma ngaphezulu, kuye ngezidingo zohlelo lokusebenza.

2. Amandla Aphezulu: Ngenxa yobude besikhathi sokushaya kwenhliziyo obufushane kakhulu, amandla aphezulu angafinyelela kuma-kilowatts amaningana kuya kumakhulu ama-kilowatts. Isibonelo, amanye ama-laser e-femtosecond agcina amandla ajwayelekile angu-1W, kuyilapho amandla awo aphezulu ephakeme kakhulu.

Ezinye izinkomba zokusebenza ezibalulekile zifaka phakathi izinga lokuphindaphinda kwe-pulse, amandla e-pulse, kanye nobubanzi be-pulse, konke okumele kulungiselelwe ngokusekelwe ezidingweni ezithile zezimboni nezocwaningo.

Abakhiqizi Abahamba Phambili kanye Nokuthuthukiswa Kwemboni

Abakhiqizi abaningana bomhlaba wonke babusa imboni ye-laser esheshayo:

1. I-Coherent, i-Spectra-Physics, i-Newport (MKS) – Izinkampani ezisunguliwe ezinobuchwepheshe obuvuthiwe kanye nezinhlelo zokusebenza eziningi zezimboni nezesayensi.

2. I-TRUMPF, i-IPG Photonics – Abaholi bemakethe ezixazululweni zokucubungula i-laser yezimboni.

3. Abakhiqizi baseShayina (i-Han's Laser, i-GaussLasers, i-YSL Photonics) – Abadlali abasafufusa abenza intuthuko enkulu ekwakheni i-laser, ubuchwepheshe bokukhiya imodi, kanye nokuhlanganiswa kwesistimu.

Izinhlelo Zokupholisa Nokuphathwa Kokushisa

Naphezu kwamandla awo aphansi ngokwesilinganiso, ama-laser ashesha kakhulu akhiqiza ukushisa okukhulu okusheshayo ngenxa yamandla awo aphezulu. Izinhlelo zokupholisa ezisebenzayo zibalulekile ukuqinisekisa ukusebenza okuzinzile nokuphila isikhathi eside kokusebenza.

Izinhlelo Zokushisa: Ama-laser ashesha kakhulu avame ukuhlonyiswa ngama-chiller ezimboni anokunemba kokulawula izinga lokushisa okungu-±0.1°C noma okungcono ukuze alondoloze ukusebenza okuzinzile kwe-laser.

TEYU Ama-Chiller ochungechunge lwe-CWUP: Yakhelwe ngqo ukupholisa nge-laser esheshayo, lawa ma-laser chiller anikeza ukulawulwa kokushisa okulawulwa yi-PID ngokunemba okuphezulu okufika ku-0.08°C kuya ku-0.1°C. Aphinde asekele ukuxhumana kwe-RS485 kokuqapha nokulawula kude, okwenza kube kuhle kakhulu ezinhlelweni ze-laser esheshayo ezingama-3W -60W.

Amathrendi Esikhathi Esizayo Kuma-Laser Asheshayo

Imboni ye-laser esheshayo iguqukela ku:

1. Ama-Pulse Amafushane, Amandla Aphezulu Okuphezulu: Ukuthuthuka okuqhubekayo ekuvalekeni kwemodi kanye nokucindezela kwe-pulse kuzokwenza kube lula ama-laser e-attosecond pulse ukuze kusetshenziswe ngokunemba okukhulu.

2. Izinhlelo Ezihlanganisiwe Nezincane: Ama-laser asheshayo esikhathi esizayo azohlanganiswa kakhulu futhi abe lula ukuwasebenzisa, anciphise ubunzima kanye nezindleko zohlelo lokusebenza.

3. Izindleko Eziphansi Nokutholakala Kwendawo: Njengoba izingxenye ezibalulekile ezifana namakristalu e-laser, imithombo yamaphampu, kanye nezinhlelo zokupholisa zikhiqizwa ngaphakathi ezweni, izindleko ze-laser ezisheshayo zizokwehla, okwenza kube lula ukwamukelwa kabanzi.

4. Ukuhlanganiswa Kwezimboni Ezihlukahlukene: Ama-laser asheshayo azohlangana kakhulu nezinkambu ezifana nokuxhumana kwe-optical, ulwazi lwe-quantum, imishini yokunemba, kanye nocwaningo lwezokwelapha, okuqhuba ukusungulwa okusha kobuchwepheshe.

Isiphetho

Ubuchwepheshe be-laser ye-Ultrafast buthuthuka ngokushesha, bunikeza ukunemba okungenakuqhathaniswa kanye nemiphumela yokushisa emincane kuzo zonke izinkambu zezimboni, zezokwelapha, nezesayensi. Abakhiqizi abahamba phambili bayaqhubeka nokuthuthukisa amapharamitha e-laser kanye namasu okuhlanganisa ngenkathi intuthuko ezinhlelweni zokupholisa kanye nokuphathwa kokushisa ithuthukisa ukuzinza kwe-laser. Njengoba izindleko zincipha futhi izinhlelo zokusebenza zezimboni ezahlukahlukene zanda, ama-laser e-ultrafast asehlelelwe ukuguqula izimboni eziningi zobuchwepheshe obuphezulu.
