Kodi Ultrafast Lasers ndi Chiyani Ndipo Zimagwiritsidwa Ntchito Bwanji?

Tanthauzo la Ultrafast Lasers

Ma laser othamanga kwambiri amatanthauza ma laser omwe amatulutsa ma pulse afupi kwambiri, nthawi zambiri mu picosecond (masekondi 10⁻¹²) kapena femtosecond (masekondi 10⁻¹⁵). Chifukwa cha nthawi yawo yothamanga kwambiri, ma laser awa amalumikizana ndi zinthu makamaka kudzera mu zotsatira zosatentha, zopanda mzere, zomwe zimachepetsa kwambiri kufalikira kwa kutentha ndi kuwonongeka kwa kutentha. Khalidwe lapaderali limapangitsa ma laser othamanga kwambiri kukhala abwino kwambiri pa micromachining yolondola, njira zamankhwala, ndi kafukufuku wasayansi.

Kugwiritsa Ntchito Ma Laser Osafulumira

Ndi mphamvu zawo zapamwamba komanso kutentha kochepa, ma laser othamanga kwambiri amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo:

1. Industrial Micromachining: Ma laser othamanga kwambiri amathandiza kudula, kuboola, kulemba, ndi kukonza pamwamba molondola pamlingo wa micro ndi nano ndi madera ochepa omwe amakhudzidwa ndi kutentha.

2. Kujambula Zithunzi Zachipatala ndi Zamankhwala: Mu ophthalmology, ma laser a femtosecond amagwiritsidwa ntchito pa opaleshoni ya maso ya LASIK, zomwe zimapangitsa kuti cornea idulidwe bwino komanso kuti pasakhale mavuto ambiri pambuyo pa opaleshoni. Kuphatikiza apo, amagwiritsidwa ntchito pojambula ma microscopy ambiri komanso pofufuza minofu ya biomedical.

3. Kafukufuku wa Sayansi: Ma laser amenewa amagwira ntchito yofunika kwambiri pa spectroscopy yokonzedwa nthawi, ma optics osalunjika, kulamulira kwa quantum, ndi kafukufuku watsopano wa zinthu, zomwe zimathandiza asayansi kufufuza mphamvu zothamanga kwambiri pamlingo wa atomu ndi mamolekyu.

4. Kulankhulana kwa Optical: Ma laser ena othamanga kwambiri, monga ma laser a fiber a 1.5μm, amagwira ntchito mu band yolumikizirana ya fiber ya optical yomwe siitayika kwambiri, ndipo amagwira ntchito ngati magwero okhazikika a kuwala kuti deta ifalikire mwachangu.

Mphamvu ndi Magwiridwe Antchito

Ma laser othamanga kwambiri amadziwika ndi magawo awiri ofunikira a mphamvu:

1. Mphamvu yapakati: Imayambira pa ma milliwatts makumi ambiri mpaka ma watts angapo kapena kupitirira apo, kutengera zomwe zimagwiritsidwa ntchito.

2. Mphamvu Yofika Pamwamba: Chifukwa cha nthawi yochepa kwambiri ya kugunda kwa mtima, mphamvu yofika pamlingo waukulu imatha kufika pa ma kilowatts angapo mpaka ma kilowatts mazana ambiri. Mwachitsanzo, ma laser ena a femtosecond amakhala ndi mphamvu yapakati ya 1W, pomwe mphamvu yawo yofika pamlingo waukulu imakhala yokwera kwambiri.

Zizindikiro zina zofunika kwambiri zogwirira ntchito ndi monga kuchuluka kwa kubwerezabwereza kwa kugunda kwa mtima, mphamvu ya kugunda kwa mtima, ndi kukula kwa kugunda kwa mtima, zonse zomwe ziyenera kukonzedwa bwino kutengera zosowa zamakampani ndi kafukufuku.

Opanga Otsogola ndi Chitukuko cha Makampani

Opanga angapo padziko lonse lapansi amalamulira makampani opanga laser othamanga kwambiri:

1. Coherent, Spectra-Fizikisi, Newport (MKS) – Makampani okhazikika okhala ndi ukadaulo wokhwima komanso ntchito zosiyanasiyana zamafakitale ndi zasayansi.

2. TRUMPF, IPG Photonics – Atsogoleri pamsika pa njira zothetsera laser ya mafakitale.

3. Opanga aku China (Han's Laser, GaussLasers, YSL Photonics) – Osewera atsopano akupita patsogolo kwambiri pakupanga ma laser, ukadaulo wotseka mode, komanso kuphatikiza makina.

Machitidwe Oziziritsira ndi Kusamalira Kutentha

Ngakhale kuti mphamvu zake zimakhala zochepa, ma laser othamanga kwambiri amapanga kutentha kwakukulu nthawi yomweyo chifukwa cha mphamvu zawo zapamwamba kwambiri. Makina oziziritsira ogwira ntchito bwino ndi ofunikira kuti atsimikizire kuti ntchito yawo ndi yokhazikika komanso kuti ikhale nthawi yayitali.

Makina Oziziritsira: Ma laser othamanga kwambiri nthawi zambiri amakhala ndi ma chiziritsira mafakitale omwe ali ndi kulondola kowongolera kutentha kwa ± 0.1°C kapena kuposa pamenepo kuti asunge magwiridwe antchito a laser okhazikika.

TEYU CWUP-mndandanda wa Chillers: Zopangidwa makamaka kuti ziziziritse laser mwachangu kwambiri, ma laser chiller awa amapereka malamulo oyendetsera kutentha kolamulidwa ndi PID molondola kwambiri mpaka 0.08°C mpaka 0.1°C. Amathandizanso kulumikizana kwa RS485 kuti aziyang'anira ndikuwongolera kutali, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pamakina a laser othamanga kwambiri a 3W -60W.

Zochitika Zamtsogolo mu Ultrafast Lasers

Makampani opanga laser othamanga kwambiri akusintha kupita ku:

1. Ma pulses Afupi, Mphamvu Yaikulu Kwambiri: Kupita patsogolo kosalekeza mu mode-locking ndi pulse compression kudzalola ma attosecond pulse lasers kuti agwiritsidwe ntchito molondola kwambiri.

2. Makina Osiyanasiyana ndi Ang'onoang'ono: Ma laser othamanga kwambiri amtsogolo adzakhala ogwirizana komanso osavuta kugwiritsa ntchito, zomwe zimachepetsa zovuta komanso ndalama zogwiritsira ntchito.

3. Kuchepetsa Mtengo ndi Kupezeka kwa Malo: Pamene zinthu zofunika monga makristalo a laser, magwero a mapampu, ndi makina ozizira akupangidwa m'dziko muno, mitengo ya laser yofulumira kwambiri idzatsika, zomwe zidzathandiza kuti anthu ambiri azigwiritsa ntchito.

4. Kuphatikiza Makampani Osiyanasiyana: Ma laser othamanga kwambiri adzagwirizana kwambiri ndi magawo monga kulumikizana kwa kuwala, chidziwitso cha quantum, makina olondola, ndi kafukufuku wa zamankhwala, zomwe zikuyendetsa zatsopano zaukadaulo.

Mapeto

Ukadaulo wa laser wothamanga kwambiri ukupita patsogolo mofulumira, ukupereka kulondola kosayerekezeka komanso zotsatira zochepa za kutentha m'magawo a mafakitale, azachipatala, ndi asayansi. Opanga otsogola akupitilizabe kukonza magawo a laser ndi njira zolumikizirana pomwe kupita patsogolo mu makina oziziritsa ndi owongolera kutentha kumawonjezera kukhazikika kwa laser. Pamene ndalama zikuchepa komanso ntchito zamafakitale osiyanasiyana zikuchulukirachulukira, ma laser othamanga kwambiri akukonzekera kusintha mafakitale ambiri apamwamba.
