Chii chinonzi Ultrafast Lasers uye Chinoshandiswa Sei?

Tsanangudzo yeUltrafast Lasers

MaLaser eUltrafast anoreva maLaser anoburitsa mapulse mapfupi zvikuru, anowanzova muchikamu chepicosecond (10⁻¹² masekondi) kana femtosecond (10⁻¹⁵ masekondi). Nekuda kwenguva yavo yekurova kwemoyo pfupi, maLaser aya anoshanda nezvinhu zvakanyanya kuburikidza nemhedzisiro isiri yekupisa, isiri yemutsara, zvichideredza zvakanyanya kupararira kwekupisa uye kukuvara kwekupisa. Hunhu uhu hwakasiyana hunoita kuti maLaser eultrafast ave akakodzera kugadzira micromachines nemazvo, maitiro ekurapa, uye kutsvagisa kwesainzi.

Mashandisirwo eUltrafast Lasers

Nesimba ravo repamusoro-soro uye simba shoma rekupisa, ma-laser e-ultrafast anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, anosanganisira:

1. Kugadzira Machining eIndasitiri: Malaser anokurumidza kwazvo anogonesa kucheka, kuboora, kuisa mamaki, uye kugadzirisa pamusoro nemazvo pamazinga madiki neasina kupisa zvakanyanya.

2. Kufungidzira Zvekurapa uye Zvekurapa: Mukurapa maziso, femtosecond lasers inoshandiswa pakuvhiyiwa kwemaziso kweLASIK, zvichipa kucheka kwekona kwakanyatsojeka pasina matambudziko akawanda mushure mekuvhiyiwa. Pamusoro pezvo, zvinoshandiswa mu multiphoton microscopy uye biomedical tissue analysis.

3. Tsvagiridzo yeSainzi: Malaser aya anoita basa rakakosha mukuongorora spectroscopy yakagadziriswa nenguva, optics dzisina kurongeka, kudzora kwequantum, uye tsvagiridzo itsva yezvinhu, zvichibvumira masayendisiti kuongorora mafambiro ekukurumidza pamazinga eatomu nemamorekuru.

4. Kutaurirana Kwemaziso: Mamwe ma laser anokurumidza, akadai se 1.5μm fiber lasers, anoshanda mubhendi rekutaurirana re optical fiber risingarasikirwe zvakanyanya, achishanda senzvimbo dzakagadzikana dzekutumira data nekukurumidza.

MaParamende eSimba neKushanda

Ma lasers e Ultrafast anozivikanwa nematanho maviri makuru esimba:

1. Simba reAvhareji: Rinotangira pamakumi emamilliwatts kusvika pamawatts akati wandei kana kupfuura, zvichienderana nezvinodiwa pakushandisa.

2. Simba Rinorema: Nekuda kwenguva pfupi kwazvo yekurova kwemoyo, simba rinorema rinogona kusvika makilowatts akawanda kusvika kumazana emakilowatts. Semuenzaniso, mamwe mafemtosecond lasers ane simba repakati re1W, nepo simba rawo rinorema riri pamusoro pehukuru hwakati wandei.

Zvimwe zviratidzo zvakakosha zvekushanda zvinosanganisira mwero wekudzokorora kwesimba remwoyo, simba remwoyo, uye upamhi hwemwoyo, zvese izvi zvinofanirwa kugadziriswa zvichienderana nezvinodiwa nemaindasitiri netsvagiridzo.

Vagadziri Vanotungamira uye Kubudirira Kwemaindasitiri

Vagadziri vakawanda vepasi rose vanotungamira indasitiri yelaser ye ultrafast:

1. Coherent, Spectra-Fizikisi, Newport (MKS) – Makambani akasimbiswa ane tekinoroji yakakura uye akasiyana-siyana emashandisirwo emaindasitiri nesainzi.

2. TRUMPF, IPG Photonics - Vanotungamira mumusika mukugadzirisa maindasitiri nelaser.

3. Vagadziri vekuChina (Han's Laser, GaussLasers, YSL Photonics) – Vatambi vari kusimukira vari kuita kufambira mberi kukuru mukugadzira laser, matekinoroji ekugadzirisa mode, uye kubatanidzwa kwemasisitimu.

Masisitimu Ekutonhodza uye Kutarisira Kupisa

Pasinei nesimba rayo shoma, ma laser anokurumidza zvikuru anogadzira kupisa kukuru ipapo ipapo nekuda kwesimba rayo repamusoro. Masisitimu ekutonhodza anoshanda zvakanaka akakosha kuti ave nechokwadi chekuti mashandiro awo akasimba uye kuti agare kwenguva refu.

Masisitimu eChiller: MaLaser eUltrafast anowanzo shongedzwa nemaIndustrial chillers ane tembiricha yekudzora chaiyo ye ±0.1°C kana zviri nani kuti arambe achishanda zvakanaka neLaser.

TEYU CWUP-series Chillers: Yakagadzirirwa kutonhora kwelaser nekukurumidza, ma laser chiller aya anopa kudzorwa kwekupisa kunodzorwa nePID nemazvo kusvika pa0.08°C kusvika 0.1°C. Anotsigirawo RS485 kutaurirana kwekutarisa nekudzora uri kure, zvichiita kuti ive yakakodzera masisitimu elaser anokurumidza kumhanya e3W -60W.

Mafambiro Emangwana muUltrafast Lasers

Indasitiri ye laser inokurumidza zvikuru iri kufambira mberi ichienda ku:

1. Kupfupika kwePulses, Simba Rakakwirira rePeak: Kufambira mberi kuri kuitwa mukugadzirisa modhi uye kudzvanywa kwepulse kuchaita kuti lasers dzepulse dzeattosecond dzikwanise kushandiswa nemazvo zvakanyanya.

2. Masisitimu Akamanikana uye Akapfava: Malaser emagetsi anokurumidza kushanda munguva yemberi achava akabatanidzwa zvakanyanya uye ari nyore kushandisa, zvichideredza kuoma uye mari yekushandisa.

3. Kuderedza Mari uye Kushandiswa Kwenzvimbo: Sezvo zvinhu zvakakosha zvakaita semakristaro elaser, mapombi, uye masisitimu ekutonhodza zvichigadzirwa munyika, mitengo yelaser inokurumidza zvikuru ichaderera, zvichiita kuti zvikwanise kushandiswa zvakanyanya.

4. Kubatanidzwa Kwemaindasitiri Akabatana: Malaser eUltrafast achawedzera kubatana nenzvimbo dzakadai sekutaurirana kwemaziso, ruzivo rwe quantum, machining akanyatsogadzirwa, uye tsvakiridzo yezvekurapa, zvichitungamira hunyanzvi hutsva hwetekinoroji.

Mhedziso

Tekinoroji yeLaser yeUltrafast iri kufambira mberi nekukurumidza, ichipa kunyatsojeka kusingaenzaniswi uye mhedzisiro shoma yekupisa mumaindasitiri, ekurapa, uye esainzi. Vagadziri vanotungamira vari kuramba vachivandudza maparamita eLaser uye matekiniki ekubatanidza ukuwo kufambira mberi mumaitiro ekutonhodza uye ekutarisira kupisa kuchivandudza kugadzikana kweLaser. Sezvo mitengo ichiderera uye mashandisirwo emaindasitiri akasiyana-siyana achikura, maLaser eUltrafast akagadzirirwa kuchinja maindasitiri mazhinji etekinoroji yepamusoro.
