Ko laser inogona kucheka madhaimani here?
Ehe, malaser anogona kucheka madhaimani, uye nzira iyi yave kufarirwa zvakanyanya muindasitiri yemadhaimani nekuda kwezvikonzero zvakasiyana-siyana. Kucheka nelaser kunopa kunyatsojeka, kushanda zvakanaka, uye kugona kugadzira kucheka kwakaomarara kwakaoma kana kusingagoneki nenzira dzechinyakare dzekucheka nekanika.
Ndeipi nzira yechinyakare yekucheka madhaimani?
Dambudziko Mukucheka Nekucheka Madhaimani
Dhaimani, sezvo iri yakaoma, isina kusimba, uye isingachinji makemikari, inokonzera matambudziko makuru pakucheka. Nzira dzechinyakare, dzinosanganisira kucheka nemakemikari uye kupukuta, dzinowanzo kukonzera mitengo yakakwira yevashandi uye zvikanganiso, pamwe nematambudziko akadai sekutsemuka, machipisi, uye kupfeka kwemidziyo. Zvichienderana nekuti kucheka kwacho kwakanyatsojeka, nzira idzi hadzina kunaka.
Tekinoroji yekucheka nelaser inobuda senzira yepamusoro, ichipa kucheka nekukurumidza, kwepamusoro-soro kwezvinhu zvakaoma, zvinoputsika senge dhaimani. Iyi nzira inoderedza kupisa, inoderedza njodzi yekukuvadzwa, zvikanganiso zvakaita sekutsemuka nekupwanyika, uye inovandudza mashandiro ekugadzirisa. Inokurumidza kumhanya, mitengo yemidziyo yakaderera, uye zvikanganiso zvishoma zvichienzaniswa nenzira dzemaoko. Mhinduro yakakosha yelaser mukucheka nedhaimani ndiyoDPSS (Diode-Pumped Solid-State) Nd: YAG (Neodymium-doped Yttrium Aluminum Garnet) laser, iyo inoburitsa chiedza chegirini che532 nm, ichivandudza kunaka kwekucheka uye kunaka.
4 Mabhenefiti makuru ekucheka madhaimani nelaser
01
Kunyatsojeka Kusina Kuenzana
Kucheka neLaser kunobvumira kucheka kwakanyatsojeka uye kwakaoma, zvichigonesa kugadzirwa kwemagadzirirwo akaomarara ane kunyatsorongeka uye marara mashoma.
02
Kushanda Nesimba Uye Kumhanya
Maitiro acho anokurumidza uye anoshanda zviri nani, zvichideredza zvakanyanya nguva yekugadzira uye zvichiwedzera huwandu hwemadhaimani anoshandiswa nevagadziri.
03
Kuchinja-chinja muKugadzira
MaLaser anopa mukana wekugadzira maumbirwo akasiyana-siyana nemagadzirirwo, achigadzirisa kucheka kwakaoma uye kwakapfava uko nzira dzechinyakare dzisingagoni kuita.
04
Kuchengetedzwa Kwakawedzerwa & Hunhu
Nekucheka nelaser, pane mukana mudiki wekukuvadzwa kwemadhaimani uye mukana mudiki wekukuvadzwa kwemushandisi, zvichiita kuti kucheka kwemhando yepamusoro uye mamiriro ekushanda akachengeteka.
DPSS Nd: Yag Laser Application muKucheka Dhaimani
Laser yeDPSS (Diode-Pumped Solid-State) Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) inogadzira chiedza chegirini che532 nm chakapetwa kaviri inoshanda nenzira yakaoma inosanganisira zvinhu zvakakosha uye misimboti yemuviri.

- Nd:YAG laser ine chivharo chakavhurika inoratidza 532 nm green light yakapetwa kaviri
Nheyo yekushanda yeDPSS Laser
1. Kupomba Diode:
Maitiro acho anotanga ne laser diode, iyo inoburitsa chiedza che infrared. Chiedza ichi chinoshandiswa "kupomba" kristaro yeNd:YAG, zvichireva kuti inomutsa ma neodymium ions ari mu yttrium aluminium garnet crystal lattice. Laser diode yakagadziriswa kuti ienderane ne wavelength inoenderana ne absorption spectrum yeNd ions, zvichiita kuti simba rifambe zvakanaka.
2. Nd:YAG Kristaro:
Kristaro yeNd:YAG ndiyo nzira inoshanda yekuwana simba. Kana maion eNeodymium amutswa nechiedza chinopomba, anotora simba oenda kune imwe nzira ine simba rakawanda. Mushure menguva pfupi, maion aya anodzokera kune imwe nzira ine simba rakaderera, achiburitsa simba rawo rakachengetwa muchimiro chemaphoton. Maitiro aya anonzi emission inongoerekana yabuda.
[Verenga zvakawanda:Sei tichishandisa kristaro yeNd YAG senzira yekuwana simba muDPSS laser?? ]
3. Kuchinja Kwehuwandu hwevanhu uye Kuburitswa Kwemhepo:
Kuti chiitiko chelaser chiitike, panofanira kuva nekuchinja kwehuwandu hwevanhu, uko maion akawanda ari muchimiro chekufara kupfuura ari muchimiro chesimba rakaderera. Sezvo maphoton achibhururuka pakati pemagirazi elaser cavity, anokurudzira maion eNd anofara kuti aburitse maphoton akawanda echikamu chimwe chete, divi, uye wavelength. Maitiro aya anozivikanwa se stimulated emission, uye anowedzera simba rechiedza mukati mekristaro.
4. Mhara yeLaser:
Mugodhi welaser unowanzova nemagirazi maviri kumagumo ese ekristaro yeNd:YAG. Rimwe girazi rinopenya zvakanyanya, uye rimwe rinopenya zvishoma, zvichiita kuti chiedza chibude sezvo laser inobuda. Mugodhi unoenderana nechiedza, zvichiita kuti chiwedzere simba kuburikidza nekutenderera kunodzokororwa kwekubuda kwacho.
5. Kuwanda Kwakapetwa Kaviri (Kugadzirwa Kwechipiri KweHarmonic):
Kuti chiedza chefrequency chishandurwe (chinowanzo 1064 nm chinoburitswa neNd:YAG) chiite chiedza chegirini (532 nm), kristaro inopetwa kaviri (yakadai seKTP - Potassium Titanyl Phosphate) inoiswa munzira yelaser. Kristaro iyi ine chimiro che optical chisiri chemutsara chinoibvumira kutora ma photon maviri echiedza che infrared chekutanga uye kuasanganisa kuita photon imwe chete ine simba rakapetwa kaviri, uye nekudaro, hafu yewavelength yechiedza chekutanga. Maitiro aya anozivikanwa se second harmonic generation (SHG).
6. Kubuda kweGreen Light:
Mugumisiro wekuwedzera kaviri kwechiedza ichi ndiko kubuda kwechiedza chegirini chakajeka pa532 nm. Chiedza ichi chegirini chinogona kushandiswa mumabasa akasiyana-siyana, kusanganisira ma laser pointers, laser shows, fluorescence excitation mu microscopy, uye maitiro ekurapa.
Maitiro ese aya anoshanda zvakanyanya uye anobvumira kugadzirwa kwechiedza chegirini chine simba guru, chakabatana muchimiro chakamanikana uye chakavimbika. Chinhu chikuru chinoita kuti DPSS laser ibudirire ndechekusanganisa solid-state gain media (Nd:YAG crystal), kupomba diode zvakanaka, uye kupetwa kaviri kwema frequency anoshanda kuti chiedza chisvike pahurefu hwewavelength hwaunoda.
Sevhisi yeOEM Inowanikwa
Basa rekugadzirisa rinowanikwa kutsigira marudzi ese ezvinodiwa
Kuchenesa neLaser, kufukidza neLaser, kucheka neLaser, uye mabhokisi ekucheka nematombo anokosha.
