Njikwa okpomọkụ ziri ezi maka sistemụ Laser na ngwa nrụpụta kemgbe 2002
Asụsụ
Laser Ultrafast na-ewepụta mkpirisi mkpirisi dị mkpụmkpụ na picosecond ruo femtosecond nso, na-eme ka nhazi nke ọma dị elu, na-abụghị nke ọkụ. A na-eji ha eme ihe na microfabrication nke ụlọ ọrụ mmepụta ihe, ịwa ahụ ahụike, nchọpụta sayensị, na nkwurịta okwu anya. Sistemụ jụrụ oyi dị elu dị ka TEYU CWUP-usoro chillers na-ahụ maka ọrụ kwụsiri ike. Ọdịnihu na-eme n'ọdịnihu na-elekwasị anya na mkpirisi mkpirisi, njikọta dị elu, mbelata ọnụ ahịa, yana ngwa ụlọ ọrụ gafere.
Nkọwa nke Ultrafast Lasers
Laser Ultrafast na-ezo aka na lasers nke na-ewepụta mkpirisi mkpirisi nke ukwuu, nke na-adịkarị na nkeji picosecond (10⁻¹²) ma ọ bụ femtosecond (10⁻¹⁵ sekọnd). N'ihi ogologo oge pulse ha dị mkpụmkpụ, lasers ndị a na-eji ihe emekọrịta ihe bụ isi site na mmetụta na-abụghị thermal, nke na-abụghị nke ntanetị, na-ebelata mgbasa ọkụ na mmebi ọkụ. Njirimara a pụrụ iche na-eme ka laser ultrafast dị mma maka micromachining ziri ezi, usoro ahụike na nyocha sayensị.
Ngwa nke Ultrafast Lasers
Site na ike ha dị elu yana obere mmetụta ọkụ, a na-etinye laser ultrafast n'ọtụtụ ebe n'ofe ụlọ ọrụ dị iche iche, gụnyere:
1. Micromachining ụlọ ọrụ: Ultrafast lasers na-enyere aka ịkpụ, ịkụ ala, akara, na nhazi elu na ọkwa micro na nano na mpaghara okpomọkụ na-emetụta ntakịrị.
2. Medical and Biomedical Imaging: Na ophthalmology, femtosecond lasers na-eji maka ịwa ahụ anya LASIK, na-enye nkenke corneal nkenke na obere nsogbu mgbe ịwa ahụ gasịrị. Na mgbakwunye, a na-etinye ha na microscope multiphoton na nyocha anụ ahụ biomedical.
3. Nnyocha sayensị: Ndị lasers ndị a na-arụ ọrụ dị oke mkpa na spectroscopy nke edoziri oge, optics na-adịghị anya, njikwa quantum, na nyocha ihe ọhụrụ, na-enye ndị ọkà mmụta sayensị ohere ịchọpụta ultrafast dynamics na ọkwa atomic na molecular.
4. Optical Communications: Ụfọdụ ultrafast lasers, dị ka 1.5μm fiber lasers, na-arụ ọrụ na obere-efunahụ eriri nkwurịta okwu band, na-eje ozi dị ka ike ìhè isi mmalite maka elu-ọsọ data nnyefe.
Oke ike na arụmọrụ
A na-eji ọnụọgụ ike abụọ mara Ultrafast lasers:
1. Nkezi Ike: Site na iri puku kwuru iri milliwatts ruo ọtụtụ watts ma ọ bụ karịa, dabere na ngwa chọrọ.
2. Ike kacha elu: N'ihi ogologo oge pulse dị mkpụmkpụ, ike kachasị elu nwere ike iru ọtụtụ kilowatts ruo ọtụtụ narị kilowatts. Dịka ọmụmaatụ, ụfọdụ lasers femtosecond na-ejigide ike nke 1W, ebe ike ha kacha elu bụ ọtụtụ iwu nke ịdị elu dị elu.
Ngosipụta arụmọrụ ndị ọzọ dị mkpa gụnyere ọnụọgụ nkwughachi pulse, ume pulse, na obosara usu, ihe niile a ga-emerịrị dabere na mkpa ụlọ ọrụ na nyocha akọwapụtara.
Ndị na-emepụta ihe na mmepe ụlọ ọrụ
Ọtụtụ ndị nrụpụta ụwa na-achịkwa ụlọ ọrụ laser ultrafast:
1. Coherent, Spectra-Physics, Newport (MKS) - Ụlọ ọrụ guzosiri ike na nkà na ụzụ tozuru okè na ọtụtụ ọrụ mmepụta ihe na nkà mmụta sayensị.
2. TRUMPF, IPG Photonics - Market ndú na ulo oru laser nhazi ngwọta.
3. Ndị na-emepụta China (Han's Laser, GaussLasers, YSL Photonics) - Ndị na-eme egwuregwu na-eme ka ọganihu dị ịrịba ama na nhazi laser, teknụzụ mkpọchi mode, na ntinye usoro.
Sistemu jụrụ oyi na njikwa okpomọkụ
N'agbanyeghị ike ha dị ala, laser ultrafast na-emepụta oke ọkụ ozugbo n'ihi ike ha dị elu. Sistemụ jụrụ oyi nke ọma dị mkpa iji hụ na arụmọrụ kwụsiri ike yana ndụ ọrụ ogologo oge.
Chiller Systems: Ultrafast lasers na-ejikarị chillers ụlọ ọrụ nwere njikwa okpomọkụ nke ± 0.1 Celsius C ma ọ bụ ka mma iji nọgide na-arụ ọrụ laser kwụsiri ike.
TEYU CWUP-usoro Chillers : Ezubere nke ọma maka oyi laser ultrafast, chillers laser ndị a na-enye ụkpụrụ okpomọkụ na-achịkwa PID na nkenke dị elu dị ka 0.08°C ruo 0.1°C. Ha na-akwado nkwukọrịta RS485 maka nleba anya na njikwa anya, na-eme ka ha dị mma maka sistemụ laser 3W -60W ultrafast.
Ọdịnihu na-agbanwe na Ultrafast Lasers
Ụlọ ọrụ laser ultrafast na-aga n'ihu:
1. Shorter Pulses, Higher Peak Power: Na-aga n'ihu na-aga n'ihu na mkpọchi mode na mkpakọ pulse ga-enyere attosecond pulse lasers maka oke nkenke ngwa.
2. Modular na kọmpat Systems: Ọdịnihu ultrafast lasers ga-abụ ihe jikọrọ ọnụ na onye ọrụ-enyi na enyi, na-ebelata mgbagwoju anya na ngwa ngwa.
3. Lower Costs and Localization: Dị ka isi ihe dị ka laser kristal, mgbapụta isi mmalite, na jụrụ usoro na-aghọ anụ ụlọ na-emepụta, ultrafast laser akwụ ụgwọ ga-ada, ikwado sara mbara doro.
4. Cross-Industry Integration: Ultrafast lasers ga-esiwanye ike jikọọ na ubi dị ka ngwa anya nkwukọrịta, quantum ọmụma, nkenke machining, na biomedical nnyocha, na-akwọ ụgbọala ọhụrụ nkà na ụzụ ọhụrụ.
