Gịnị bụ Ultrafast Lasers na kedu ka eji ha?

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'ofe ụlọ ọrụ dị iche iche, gụnyere.:

1. Ụlọ ọrụ Micromachining: Ultrafast lasers na-enyere aka ịkpụ, mkpọpu mmiri, akara, na nhazi elu na ọkwa micro na nano nwere obere mpaghara okpomọkụ metụtara.

2. Ahụhụ ahụike na biomedical: Na ophthalmology, a na-eji laser femtosecond maka ịwa ahụ anya LASIK, na-enye mbelata corneal nke ọma na obere nsogbu 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-anọghị n'ịntanetị, njikwa quantum, na nyocha ihe ọhụrụ, na-enye ndị ọkà mmụta sayensị ohere inyocha ike ultrafast na ọkwa atọm na molecular.

4. Nkwukọrịta ngwa anya: Ụfọdụ lasers ultrafast, dị ka 1.5μm fiber lasers, na-arụ ọrụ na eriri nkwurịta okwu fiber optical dị ala, na-eje ozi dị ka isi iyi ọkụ siri ike maka nnyefe data dị elu.

Oke ike na arụmọrụ

A na-eji akara ike isi abụọ mara Ultrafast lasers:

1. Nkezi Ike: Oke sitere 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 kacha 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 na-emepụta ụwa na-achịkwa ụlọ ọrụ laser ultrafast:

1. Nkwekọrịta, Spectra-Physics, Newport (MKS) - Ụlọ ọrụ guzosiri ike na nkà na ụzụ tozuru okè na ọtụtụ ngwa 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 egwuregwu na-emepe emepe na-enwe ọganihu dị ukwuu na nhazi laser, teknụzụ mkpọchi mode, na ntinye usoro.

Sistemu jụrụ oyi na njikwa okpomọkụ

N'agbanyeghị ike ha dị ala, lasers ultrafast na-emepụta nnukwu okpomọkụ ozugbo n'ihi ike ha dị elu. Sistemu jụrụ oyi nke ọma dị mkpa iji hụ na arụmọrụ kwụsiri ike yana ndụ ọrụ ogologo oge.

Sistemụ Chiller: Ultrafast lasers na-ejikarị chillers ụlọ ọrụ nwere njikwa njikwa okpomọkụ nke ± 0.1 Celsius 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

The ultrafast laser ụlọ ọrụ na-evolushọn kwupụta:

1. Ọkụ dị mkpụmkpụ, Ike kacha elu: Ọganihu na-aga n'ihu na mkpọchi ọnọdụ na mkpakọ pulse ga-eme ka lasers pulse nke abụọ na-eme ka ọ bụrụ ngwa dị oke oke.

2. Sistemụ modul na kọmpat: Ọdịnihu lasers ultrafast ga-ejikọta ya na enyi na enyi, na-ebelata mgbagwoju anya na ụgwọ ngwa.

3. Ọnụ ala ala na nhazi mpaghara: Dị ka ihe ndị dị mkpa dị ka kristal laser, isi mmalite mgbapụta, na sistemu jụrụ oyi na-emepụta n'ụlọ, ọnụ ahịa laser ultrafast ga-agbada, na-eme ka nnabata sara mbara.

4. Cross-Industry Njikọta: Laser Ultrafast ga-ejikọwanye ya na mpaghara dị ka nkwukọrịta anya, ozi ọnụọgụ, igwe ziri ezi, na nyocha biomedical, na-ebupụta ihe ọhụrụ teknụzụ ọhụrụ.
