Chii chinonzi Ultrafast Lasers uye Inoshandiswa Sei?

Tsanangudzo ye Ultrafast Lasers

Ultrafast lasers inoreva ma lasers anoburitsa yakanyanya kupfupika pulses, kazhinji mupiccosecond (10⁻¹² masekonzi) kana femtosecond (10⁻¹⁵ masekonzi) renji. Nekuda kwekureba kwavo kwe-ultra-short pulse, ma lasers aya anodyidzana nezvinhu zvakanyanya kuburikidza neasina-kupisa, nonlinear mhedzisiro, zvakanyanya kuderedza kupisa kupararira uye kukuvara kwekupisa. Ichi chakasarudzika hunhu chinoita kuti ultrafast lasers ive yakakodzera kune chaiyo micromachining, maitiro ekurapa, uye tsvagiridzo yesainzi.

Zvikumbiro zve Ultrafast Lasers

Nesimba ravo repamusoro pepamusoro uye kushomeka kwemafuta ekupisa, ma lasers ekupedzisira anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira.:

1. Industrial Micromachining: Ultrafast lasers inogonesa kucheka chaiko, kudhirowa, kumaka, uye kugadzirisa pamusoro peiyo micro uye nano mazinga ane mashoma anopisa-anokanganisa nzvimbo.

2. Medical uye Biomedical Imaging: Muophthalmology, femtosecond lasers inoshandiswa pakuvhiya ziso reLASIK, ichipa kucheka chaiko kwecorneal ine mashoma mushure mekuvhiyiwa matambudziko. Pamusoro pezvo, iwo anoshandiswa mumultiphoton microscopy uye biomedical tissue analysis.

3. Tsvakurudzo yeSainzi: Aya ma lasers anoita basa rakakosha mukugadziriswa-nguva-yakagadziriswa spectroscopy, nonlinear optics, quantum control, uye kutsvagisa kwezvinhu zvitsva, zvichibvumira masayendisiti kuongorora ekupedzisira dynamics paatomu uye mamorekuru.

4. Optical Communications: Mamwe ma lasers ekupedzisira, akadai se 1.5μm faibha lasers, anoshanda mune yakaderera-kurasikirwa optical faibha yekutaurirana bhendi, ichishanda seyakagadzika mwenje masosi epamusoro-kumhanya kufambisa data.

Simba uye Performance Parameters

Ultrafast lasers inoratidzirwa nemaviri akakosha simba paramita:

1. Avhareji Simba: Kubva pamakumi emamilliwatts kusvika kune akati wandei watts kana kupfuura, zvichienderana nezvinodiwa zvekushandisa.

2. Peak Power: Nekuda kweiyo pfupi pfupi yekupuruzira nguva, simba repamusoro rinogona kusvika kune akati wandei kilowatts kusvika kumazana emakilowatts. Semuyenzaniso, mamwe femtosecond lasers anochengetedza avhareji simba re1W, nepo simba ravo repamusoro riine maodha akati wandei ehukuru hwepamusoro.

Zvimwe zvakakosha zvinoratidzira zvinosanganisira kudzokororwa kwe pulse, pulse simba, uye pulse hupamhi, zvese izvo zvinofanirwa kugadzirwa zvichibva pane chaiyo maindasitiri nekutsvaga zvinodiwa.

Vanotungamira Vagadziri uye Kuvandudza Indasitiri

Vagadziri vanoverengeka vepasirese vanotonga iyo Ultrafast laser indasitiri:

1. Yakabatana, Spectra-Fizikisi, Newport (MKS) -Makambani akagadzwa ane tekinoroji yakakura uye huwandu hwakawanda hwemaindasitiri nesainzi mashandisirwo.

2. TRUMPF, IPG Photonics -Vatungamiriri vemusika mune maindasitiri laser kugadzirisa mhinduro.

3. Vagadziri veChinese (Han's Laser, GaussLasers, YSL Photonics) -Vatambi vari kusimukira vari kuita kufambira mberi kwakakosha mukugadzirisa laser, mode-locking tekinoroji, uye system yekubatanidza.

Kutonhodza Systems uye Thermal Management

Kunyangwe iwo akadzikira avhareji simba, ultrafast lasers inogadzira yakanyanya kupisa nekukurumidza nekuda kwesimba rawo repamusoro. Masisitimu ekutonhodza anoshanda akakosha kuti ave nechokwadi chekushanda kwakagadzikana uye hupenyu hurefu hwekushanda.

Chiller Systems: Ultrafast lasers anowanzo kuve akashongedzerwa nemaindasitiri ekutonhora ane tembiricha yekudzora ye ± 0.1 ° C kana zvirinani kuchengetedza yakagadzikana laser performance.

TEYU CWUP-yakatevedzana Chillers : Yakagadzirirwa yakanyatso kutonhora kwelaser kutonhora, aya ma laser chiller anopa PID-inodzorwa tembiricha mutemo nekurongeka kwakakwira kusvika 0.08°C kusvika 0.1°C. Ivo zvakare vanotsigira RS485 kutaurirana kwekutarisa kure uye kutonga, zvichiita kuti ive yakanakira 3W -60W ultrafast laser system.

Ramangwana Trends mu Ultrafast Lasers

Iyo ultrafast laser indasitiri iri kusimukira yakananga:

1. Shorter Pulses, Higher Peak Power: Kuenderera mberi kufambira mberi mu-modhi-kukiya uye pulse compression inogonesa attosecond pulse lasers kune yakanyanyisa kunyatso kunyorera.

2. Modular uye Compact Systems: Ramangwana ultrafast lasers ichave yakawedzera kubatanidzwa uye mushandisi-inoshamwaridzika, ichidzikisa kuoma uye mutengo wekushandisa.

3. Mutengo wakaderera uye Localization: Sezvinoita zvakakosha senge laser makristasi, pombi masosi, uye kutonhora masisitimu anogadzirwa mudzimba, Ultrafast laser mutengo unodzikira, uchifambisa kurerwa kwakawanda.

4. Cross-Industry Integration: Ultrafast lasers inowedzera kusangana neminda senge optical communications, quantum information, precision machining, uye biomedical research, kutyaira hutsva hwetekinoroji.

Mhedziso

Ultrafast laser tekinoroji iri kukurumidza kufambira mberi, ichipa kunyatsojeka kusingaenzaniswi uye kushoma kwemafuta mhedzisiro mumaindasitiri, ekurapa, uye nesainzi minda. Vagadziri vanotungamira vanoenderera mberi nekunatsiridza laser paramita uye nzira dzekubatanidza uku kufambira mberi mukutonhodza uye kudziya kwekutonga masisitimu kunosimudzira kugadzikana kwelaser. Sezvo mutengo uchidzikira uye kuyambuka-indasitiri maapplication achiwedzera, ekupedzisira-laser anoiswa kuti agadzirise akawanda epamusoro-tech maindasitiri.
