Laser kucheka madhaimani here?
Ehe, lasers anogona kucheka madhaimani, uye nzira iyi yave kuwedzera mukurumbira muindasitiri yemadhaimani nekuda kwezvikonzero zvakati wandei. Laser yekucheka inopa kunyatsoita, kunyatsoita, uye kugona kugadzira kucheka kwakaomarara kwakaoma kana kusagoneka kuwana nenzira dzechinyakare dzekucheka michina.
Ndeipi nzira yechinyakare yekucheka madhaimani?
Dambudziko MuKucheka Nemadhaimani & Sawing
Dhaimondi, kuoma, brittle, uye kugadzikana kwemakemikari, zvinounza matambudziko makuru ekucheka maitiro. Nzira dzechinyakare, dzinosanganisira kucheka makemikari uye kupenya kwemuviri, kazhinji kunokonzeresa kudhura kwevashandi uye mitengo yekukanganisa, pamwe nenyaya dzakaita sekutsemuka, machipisi, uye kupfeka kwemidziyo. Tichifunga nezve kudiwa kweiyo micron-level yekucheka chaiko, nzira idzi dzinodonha.
Laser yekucheka tekinoroji inobuda seimwe yemhando yepamusoro, inopa yakakwirira-kumhanya, yemhando yepamusoro yekucheka kwezvakaoma, brittle zvinhu sedhaimani. Iyi nzira inoderedza kupisa kwekupisa, kuderedza njodzi yekukuvara, kuremara kwakadai sekutsemuka uye kucheka, uye kunatsiridza mashandiro ekugadzirisa. Inozvirumbidza nekukurumidza, yakaderera mutengo wemidziyo, uye yakaderedzwa zvikanganiso zvichienzaniswa nemanyorero nzira. Yakakosha laser mhinduro mukucheka kwedhaimani ndiyoDPSS (Diode-Pumped Solid-State) Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) laser, iyo inoburitsa 532 nm girini mwenje, inosimudzira kucheka chaiko uye mhando.
4 Mabhenefiti makuru ekucheka kwelaser diamond
01
Unmatched Precision
Laser yekucheka inobvumira kuchekwa kwakanyatso uye kwakaomesesa, kugonesa kusikwa kweakaomesesa dhizaini nehupamhi hwechokwadi uye kushoma tsvina.
02
Kubudirira uye Kukurumidza
Maitiro acho anokurumidza uye anoshanda zvakanyanya, zvakanyanya kudzikisa nguva dzekugadzira uye kuwedzera throughput kune vanogadzira madhaimani.
03
Zvakasiyana-siyana Mukugadzira
Lasers inopa kuchinjika kuburitsa akasiyana maumbirwo uye magadzirirwo, anogara akaomesesa uye akatetema makucheka ayo echinyakare nzira haakwanise kuwana.
04
Kuwedzeredzwa Kuchengetedzeka & Hunhu
Nekucheka kwelaser, kune njodzi yakaderedzwa yekukuvara kumadhaimani uye mukana wakaderera wekukuvara kweanoshanda, kuve nechokwadi chekucheka kwemhando yepamusoro uye yakachengeteka mamiriro ekushanda.
DPSS Nd: YAG Laser Chikumbiro muDaimani Kucheka
A DPSS (Diode-Pumped Solid-State) Nd:YAG (Neodymium-doped Yttrium Aluminium Garnet) laser inogadzira frequency-yakapetwa kaviri 532 nm girinhi mwenje inoshanda kuburikidza neyakaomesesa maitiro anosanganisira akati wandei makiyi zvikamu uye misimboti yemuviri.

Kushanda Nheyo yeDPSS Laser
1. Diode Pumping:
Iyo nzira inotanga nelaser diode, iyo inoburitsa infrared mwenje. Chiedza ichi chinoshandiswa "kupomba" iyo Nd:YAG crystal, zvichireva kuti inonakidza neodymium ions yakamisikidzwa muyttrium aluminium garnet crystal lattice. Iyo laser diode inotaridzwa kune wavelength inofanana nekunyudza spectrum yeNd ion, kuve nechokwadi chekufambisa kwesimba.
2. Nd:YAG Crystal:
Iyo Nd: YAG crystal ndiyo inoshanda kuwana svikiro. Kana iyo neodymium ions ichifadzwa nechiedza chekupomba, inotora simba uye inoenda kune imwe nzvimbo ine simba. Mushure menguva pfupi, maion aya anodzokera kune yakaderera simba, achiburitsa simba rawo rakachengetwa muchimiro chephotons. Iyi nzira inodaidzwa kunzi spontaneous emission.

3. Population Inversion uye Stimulated Emission:
Kuti chiitiko chelaser chiitike, kuchinjika kwehuwandu kunofanirwa kuwanikwa, uko maion akawanda ari munzvimbo yekunakidzwa kupfuura munzvimbo yepasi simba. Sezvo mafotoni anosvetuka achidzoka nekudzoka pakati pezvionioni zvelaser cavity, anomutsa iyo Nd ion inofara kuburitsa mamwe mafotoni echikamu chimwe chete, kutungamira, uye wavelength. Iyi nzira inozivikanwa seyakakurudzirwa emission, uye inosimudzira kusimba kwechiedza mukati mekristaro.
4. Laser Cavity:
Iyo laser cavity inowanzove ine magirazi maviri kune chero kumagumo kweNd: YAG crystal. Rimwe girazi rinoratidza zvakanyanya, uye rimwe racho rinoratidza zvishoma, richibvumira kuti mwenje utize sekubuda kwelaser. Iyo mhango inorira nechiedza, ichikurisa kuburikidza neakawanda akadzokororwa ekusimudzwa kwekubuda.
5. Frequency Doubling (Second Harmonic Generation):
Kushandura iyo yakakosha frequency mwenje (kazhinji 1064 nm inoburitswa neNd: YAG) kune yakasvibira mwenje (532 nm), frequency-yakapetwa kaviri kristaro (yakadai seKTP - Potassium Titanyl Phosphate) inoiswa munzira ye laser. Iyi crystal ine isina-linear optical pfuma inobvumira kuti itore mafotoni maviri ekutanga infrared light uye ivasanganise muimwe photon ine kaviri simba, uye naizvozvo, hafu yewavelength yechiedza chekutanga. Iyi nzira inozivikanwa seyechipiri harmonic generation (SHG).
6. Kubuda kweGreen Light:
Mhedzisiro yeiyi frequency kupetwa kaviri ndiko kubuda kwechiedza chakajeka chegirinhi pa532 nm. Chiedza chegirini ichi chinogona kuzoshandiswa kune akasiyana maapplication, anosanganisira laser anongedza, laser show, fluorescence excitation mumicroscope, uye maitiro ekurapa.
Iyi nzira yese inoshanda zvakanyanya uye inobvumira kugadzirwa kwepamusoro-simba, yakabatana girini mwenje mune compact uye yakavimbika fomati. Kiyi yekubudirira kweDPSS laser musanganiswa weiyo solid-state kuwana midhiya (Nd: YAG crystal), inoshanda diode kupomba, uye inoshanda frequency kupeta kaviri kuti uwane yaunoda wavelength yechiedza.
