Yiziphi I-Ultrafast Lasers futhi Zisetshenziswa Kanjani?

Incazelo ye-Ultrafast Lasers

Amalaser asheshayo abhekisela kumalaser akhipha amapulse amafushane kakhulu, ngokuvamile ebangeni le-picosecond (10⁻¹²) noma i-femtosecond (amasekhondi angu-10⁻¹⁵). Ngenxa yobude bawo be-ultra-short pulse, lawa ma-laser asebenzisana nezinto ngokuyinhloko ngemiphumela engashisi, engaqondile, enciphisa kakhulu ukusabalalisa ukushisa kanye nomonakalo oshisayo. Lesi sici esiyingqayizivele senza ama-lasers asheshayo alungele ukunemba kwe-micromachining, izinqubo zezokwelapha, nocwaningo lwesayensi.

Izicelo ze-Ultrafast Lasers

Ngamandla awo aphezulu aphezulu kanye nomthelela omncane wokushisa, ama-laser asebenza kakhulu asetshenziswa kabanzi kuzo zonke izimboni ezahlukahlukene, kufaka phakathi:

1. I-Industrial Micromachining: Ama-laser asheshayo anika amandla ukusika okunembayo, ukubhola, ukumaka, nokucutshungulwa kwendawo emazingeni amancane nawe-nano anezindawo ezincane ezithinteke ekushiseni.

2. I-Medical and Biomedical imaging: Ku-ophthalmology, ama-laser we-femtosecond asetshenziselwa ukuhlinzwa kwamehlo e-LASIK, ahlinzeka ngokusikwa kwekhone okunembayo okunezinkinga ezincane zangemuva kokuhlinzwa. Ukwengeza, asetshenziswa ku-multiphoton microscopy kanye nokuhlaziywa kwezicubu ze-biomedical.

3. Ucwaningo Lwesayensi: Lawa ma-lasers adlala indima ebalulekile ekubonweni okuxazululwe isikhathi, ama-optics angaqondile, ukulawula i-quantum, kanye nocwaningo olusha lwezinto ezibonakalayo, okuvumela ososayensi ukuthi bahlole ukuguquguquka kwe-ultrafast kumazinga e-athomu namangqamuzana.

4. I-Optical Communications: Ama-laser athile ashesha kakhulu, njengama-laser wefayibha angu-1.5μm, asebenza kubhendi yokuxhumana yefayibha elahleka kancane, esebenza njengemithombo yokukhanya ezinzile yokudluliswa kwedatha ngesivinini esikhulu.

Amapharamitha Amandla Nokusebenza

Ama-laser asheshayo abonakala ngamapharamitha amabili abalulekile wamandla:

1. Amandla Amaphakathi: Ububanzi busuka emashumini ama-milliwatts kuye kuma-watts ambalwa noma ngaphezulu, kuye ngezidingo zohlelo lokusebenza.

2. Amandla Aphakeme: Ngenxa yobude besikhathi sokushaya kwenhliziyo esifushane kakhulu, amandla aphezulu angafinyelela ku-kilowatts ambalwa ukuya kumakhulu ama-kilowatts. Isibonelo, amanye ama-laser we-femtosecond agcina amandla amaphakathi angu-1W, kuyilapho amandla awo aphezulu engama-oda ambalwa obukhulu obuphezulu.

Ezinye izinkomba zokusebenza ezibalulekile zifaka izinga lokuphinda ukushaya kwenhliziyo, amandla okushaya kwenhliziyo, nobubanzi bokushaya kwenhliziyo, konke okumele kuthuthukiswe ngokusekelwe ezidingweni ezithile zezimboni nocwaningo.

Abakhiqizi Abaphambili Nokuthuthukiswa Kwezimboni

Abakhiqizi abaningana bomhlaba baphethe imboni ye-laser esheshayo:

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

2. I-TRUMPF, IPG Photonics - Abaholi bezimakethe kuzixazululo zokucubungula i-laser yezimboni.

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

Amasistimu Okupholisa kanye Nokuphathwa Kwezishisayo

Ngaphandle kwamandla awo aphansi amaphakathi, ama-laser asheshayo akhiqiza ukushisa okukhulu ngokushesha ngenxa yamandla awo aphezulu. Izinhlelo zokupholisa ezisebenzayo zibalulekile ukuze kuqinisekiswe ukusebenza okuzinzile kanye nempilo yokusebenza ende.

Amasistimu we-Chiller: Ama-laser asheshayo ajwayele ukuhlonyiswa ngezibandisi ezibandayo zasembonini ezinembayo zokulawula izinga lokushisa okungu-±0.1°C noma okungcono ukuze kugcinwe ukusebenza kwe-laser okuzinzile.

I-TEYU CWUP-uchungechunge lwe-Chillers : Idizayinelwe ngokukhethekile ukupholisa nge-laser okushesha kakhulu, lawa ma-laser chiller anikeza ukulawulwa kwezinga lokushisa okulawulwa yi-PID ngokunemba okufika ku-0.08°C kuya ku-0.1°C. Baphinde basekele ukuxhumana kwe-RS485 kokuqapha nokulawula okukude, okubenza balungele amasistimu e-laser asheshayo angu-3W -60W.

Amathrendi Azayo ku-Ultrafast Lasers

Imboni ye-laser esheshayo ithuthukela phambili:

1. Ama-Pulses amafushane, Amandla Aphakeme Aphakeme: Intuthuko eqhubekayo ekukhiyweni kwemodi kanye nokucindezelwa kokushaya kwenhliziyo kuzonika amandla amalaser we-attosecond pulse ukuze asetshenziswe ngokunemba ngokwedlulele.

2. I-Modular kanye ne-Compact Systems: Ama-laser esikhathi esizayo azohlanganiswa kakhulu futhi asebenziseke kalula, ehlise ubunkimbinkimbi nezindleko zohlelo lokusebenza.

3. Izindleko Eziphansi Nokwenziwa Kwasendaweni: Njengoba izingxenye ezibalulekile ezifana namakristalu e-laser, imithombo yephampu, nezinhlelo zokupholisa zikhiqizwa ekhaya, izindleko ze-laser ezisheshayo zizokwehla, kube lula ukutholwa okubanzi.

4. I-Cross-Industry Integration: Ama-laser asheshayo azohlangana ngokwandayo nezinkambu ezifana nezokuxhumana nge-optical, ulwazi lwe-quantum, ukunemba kwemishini, kanye nocwaningo lwe-biomedical, okuqhuba ubuciko obusha obusha.

Isiphetho

Ubuchwepheshe be-laser obusheshayo buthuthuka ngokushesha, bunikeza ukunemba okungenakuqhathaniswa kanye nemiphumela encane yokushisa kuyo yonke imikhakha yezimboni, yezokwelapha, neyesayensi. Abakhiqizi abahamba phambili bayaqhubeka nokucwenga imingcele ye-laser nezindlela zokuhlanganisa kuyilapho intuthuko ezinhlelweni zokupholisa kanye nokuphatha okushisayo ithuthukisa ukuzinza kwe-laser. Njengoba izindleko zincipha futhi izinhlelo zokusebenza zemboni ehlukahlukene zikhula, ama-laser asheshayo asethelwe ukuguqula izimboni eziningi zobuchwepheshe obuphezulu.
