Kodi Ultrafast Lasers ndi Chiyani Amagwiritsidwa Ntchito?

Tanthauzo la Ultrafast Lasers

Ma lasers othamanga kwambiri amatanthawuza ma laser omwe amatulutsa kugunda kwakufupi kwambiri, nthawi zambiri mu picosecond (10⁻¹² masekondi) kapena femtosecond (masekondi 10⁻¹⁵). Chifukwa cha nthawi yayitali kwambiri, ma lasers amalumikizana ndi zida makamaka kudzera muzopanda kutentha, zopanda malire, kuchepetsa kwambiri kufalikira kwa kutentha komanso kuwonongeka kwamafuta. Khalidwe lapaderali limapangitsa ma lasers othamanga kwambiri kukhala abwino kwa micromachining yolondola, njira zamankhwala, ndi kafukufuku wasayansi.

Kugwiritsa ntchito Ultrafast Lasers

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

1. Industrial Micromachining: Ma lasers a Ultrafast amathandizira kudula bwino, kubowola, kuyika chizindikiro, ndi kukonza pamwamba pamilingo yaying'ono ndi nano yokhala ndi madera ochepa omwe amakhudzidwa ndi kutentha.

2. Imaging Medical ndi Biomedical: Mu ophthalmology, ma lasers a femtosecond amagwiritsidwa ntchito pa opaleshoni ya maso ya LASIK, kupereka kudula kolondola kwa cornea komwe kumakhala ndi zovuta zochepa pambuyo pa opaleshoni. Kuphatikiza apo, amagwiritsidwa ntchito mu ma multiphoton microscope ndi kusanthula kwa minofu yazachilengedwe.

3. Kafukufuku wa Sayansi: Ma lasers awa amatenga gawo lofunikira pakuwonetsetsa kwanthawi yayitali, mawonekedwe osagwirizana ndi mizere, kuwongolera kwachulukidwe, ndi kafukufuku wazinthu zatsopano, kulola asayansi kuti afufuze zamphamvu kwambiri pamlingo wa atomiki ndi mamolekyulu.

4. Kulumikizana kwa Optical: Ma lasers ena othamanga kwambiri, monga ma 1.5μm CHIKWANGWANI lasers, amagwira ntchito mu otsika-kutaya kuwala CHIKWANGWANI kulankhula bandi, kutumikira monga khola magwero kuwala kwa mkulu-liwiro deta kufala.

Mphamvu ndi Magwiridwe Parameters

Ultrafast lasers imadziwika ndi magawo awiri ofunikira mphamvu:

1. Avereji Mphamvu: Kuchokera pa ma milliwatts makumi angapo mpaka ma watt angapo kapena kupitilira apo, kutengera zomwe mukufuna kugwiritsa ntchito.

2. Peak Power: Chifukwa cha kugunda kwafupipafupi kwambiri, mphamvu yapamwamba imatha kufika ma kilowatts angapo mpaka mazana a kilowatts. Mwachitsanzo, ma lasers ena a femtosecond amakhala ndi mphamvu yapakati pa 1W, pomwe mphamvu zawo zam'mwamba zimakhala zazikulu zingapo.

Zizindikiro zina zofunika zogwirira ntchito zikuphatikiza kubwereza kwa kugunda kwa mtima, mphamvu ya pulse, ndi kuchuluka kwa kugunda, zonse zomwe ziyenera kukonzedwa kutengera zosowa zamakampani ndi kafukufuku.

Opanga Otsogola ndi Chitukuko cha Makampani

Opanga angapo padziko lonse lapansi amalamulira msika wa laser wachangu kwambiri:

1. Coherent, Spectra-Physics, Newport (MKS) - Makampani omwe adakhazikitsidwa ndiukadaulo wokhwima komanso ntchito zambiri zamafakitale ndi sayansi.

2. TRUMPF, IPG Photonics - Atsogoleri amsika mumafakitale opanga laser.

3. Opanga achi China (Han's Laser, GaussLasers, YSL Photonics) - Osewera omwe akutukuka akupita patsogolo kwambiri pakumanga kwa laser, matekinoloje otsekera, komanso kuphatikiza makina.

Makina Ozizirira ndi Kuwongolera Kutentha

Ngakhale ali ndi mphamvu zochepa, ma lasers othamanga kwambiri amapanga kutentha kwambiri nthawi yomweyo chifukwa cha mphamvu zawo zapamwamba. Njira zoziziritsa bwino ndizofunikira kuti zitsimikizire kugwira ntchito mokhazikika komanso moyo wautali wogwira ntchito.

Chiller Systems: Ma lasers a Ultrafast nthawi zambiri amakhala ndi zoziziritsa kukhosi zamafakitale zomwe zimawongolera kutentha kwa ± 0.1 ° C kapena bwino kuti zisunge magwiridwe antchito a laser.

TEYU CWUP-mndandanda wa Chillers : Amapangidwa makamaka kuti azizizira kwambiri ndi laser, ma laser chiller awa amapereka malamulo owongolera kutentha oyendetsedwa ndi PID mwatsatanetsatane mpaka 0.08°C mpaka 0.1°C. Amathandiziranso kuyankhulana kwa RS485 pakuwunika ndi kuwongolera kutali, kuwapangitsa kukhala abwino kwa 3W -60W makina othamanga kwambiri a laser.

Tsogolo Latsopano mu Ultrafast Lasers

Makampani opanga laser othamanga kwambiri akupita patsogolo:

1. Kuthamanga Kwakufupi, Mphamvu Yapamwamba Yapamwamba: Kupita patsogolo kopitilira muyeso kutseka kwa mode ndi kuponderezana kwa pulse kumathandizira ma laser a attosecond pulse kuti agwiritse ntchito molondola kwambiri.

2. Modular ndi Compact Systems: Ma laser ultrafast amtsogolo adzakhala ophatikizika komanso osavuta kugwiritsa ntchito, kuchepetsa zovuta komanso ndalama zogwiritsira ntchito.

3. Mitengo Yotsika ndi Kukhazikika Kwawo: Monga zida zazikulu monga makhiristo a laser, magwero a mapampu, ndi makina oziziritsa amapangidwa m'nyumba, mtengo wa laser wachangu kwambiri udzatsika, ndikuwongolera kutengera kokulirapo.

4. Cross-Industry Integration: Ma lasers a Ultrafast adzaphatikizana kwambiri ndi minda ngati kulumikizana ndi kuwala, zambiri za kuchuluka, makina olondola, ndi kafukufuku wazachilengedwe, ndikuyendetsa zatsopano zaukadaulo.

Mapeto

Ukadaulo wa laser wa Ultrafast ukupita patsogolo mwachangu, ukupereka kulondola kosayerekezeka komanso zotsatira zochepa zamafuta m'mafakitale, zamankhwala, ndi sayansi. Opanga otsogola akupitilizabe kukonzanso magawo a laser ndi njira zophatikizira pomwe kupita patsogolo kwa njira zoziziritsira ndi kasamalidwe ka matenthedwe kumakulitsa kukhazikika kwa laser. Pamene mtengo ukucheperachepera komanso ntchito zamafakitale zikuchulukirachulukira, ma lasers othamanga kwambiri akhazikitsidwa kuti asinthe mafakitale apamwamba kwambiri.
