Idzi nzvimbo dzinokura dzekushandisa dzinoda yakakwirira-chaiyo laser girazi ine inoda dimensional kushivirira uye yakakwirira-simba laser coatings.Kushivirira kwakasimba kunopa vanobatanidza sisitimu chivimbo chekuti zvikamu zvinogona kuiswa zviri nyore mumasisitimu avo pasina kurongeka kwekutora nguva, asi izvi zvinongedzo zvinopa dambudziko kune vagadziri vegirazi remalaser.Kudzora kwemaitiro uye kutarisa kune metrology kunodiwa kune laser vagadziri vegirazi kuti vagadzire izvo zvinodikanwa zvinodikanwa kune inokura NIR laser optics nzvimbo.
SEI ERBIUM-DOPED GLASI ?
Mumakumi akati wandei emakumi emakore apfuura, kufambira mberi kwakakosha kwakaitwa muphosphate-based laser tekinoroji maererano nekuvandudzwa kwesimba rekubuda, kupfupika kwepulse nguva, kuderedzwa saizi yehurongwa, uye hutsva hwekushanda wavelengths.Er: girazi lasers rinowanzo buda paziso-rakachengetedzeka wavelengths ye1540nm, 1550nm, kana 1570nm, iyo inobatsira zvakanyanya mukutsvaga uye mamwe mamiriro apo vanhu vanogona kuoneswa matanda.Aya mawavelengths anobatsirwa nekutapurirana kwakanyanya kuburikidza nemhepo.1540nm zvakare inosangana nekushomeka kunyudzwa ne melanin, ichiita Er: girazi lasers yakakwana yeaesthetic laser application pane varwere vane rima.
Mufananidzo 1. Energy states of erbium.Er: girazi lasers anowanzo kupomba ne800nm kana 980nm laser uye emit pa1540nm kana 1570nm.
Girazi rePhosphate rinosvika pakufambiswa kwepamusoro uye rinogona kuiswa nemaatomu epasi asingawanzoita se erbium neytterbium kuitira kuti risvike pakushanduka kwehuwandu hwevanhu uye lase kana rasangana nepombi yavelength ye800nm kana 980nm (Mufananidzo 1).Er: girazi rinogonawo kupomba nemafotoni pa1480nm, asi izvi hazvidiwe nekuti kushanda zvakanaka kunogona kudzikiswa nekupomba uye kukurudzirwa kuburitsa kunoitika mune imwechete wavelength uye simba bhendi.[3]Magirazi ePhosphate anobatsirwawo nekugadzikana kwemakemikari uye yakakwira laser-induced kukuvara zvikumbaridzo (LIDTs), zvichiita kuti Er: girazi uye mamwe doped phosphate magirazi akakodzera kuNIR laser kuwana midhiya.
Magirazi ePhosphate ane kunyungudika kwakakwirira kwemaion epasi asingawanzo kupfuura magirazi esilicate, ayo ane chimiro chakanyanya kuoma matrix.[1]Nekudaro, iwo anoratidza yakatetepa bandwidth kupfuura silicate magirazi uye ane zvishoma hygroscopic, zvichireva kuti anotora hunyoro hwakawanda kubva kumhepo.Naizvozvo, ivo vanogumira kune maapplication mune yavo bandwidth uye masisitimu kwavanozove vakachengetedzwa zvakakwana kubva kune hunyoro nekuputira kana mamwe optics.
TIGHT TOLERANCES UYE PROCESS CONTROL
Zvizhinji zvezvishandiso zvakambokurukurwa, kunyanya laser rangefinding yezvidziviriro zvikumbiro, zvinowanzoda diki Er: magirazi ezvikamu zvine akanyanya kuomarara dimensional kushivirira.Aya akakwenenzverwa-akakwenenzverwa girazi relaser girazi anogona kuzodonhedzwa mumagungano asina kushoma kana kurongeka kunodiwa.Vanogona kusvika pakukura kweSIM kadhi uye kazhinji havaratidzi mabheji nekuti madiki (Mufananidzo 2).Izvi zvinoita kuti edge chipping iwedzere.Kuwana kuenderana kwakasimba uye pamusoro pemhando yakatarwa pane izvi zvidiki zvikamu zvinogona kunetsa zvakanyanya.Iyo yakajeka aperture, kana chikamu chenzvimbo yemaziso iyo inofanirwa kusangana nezvose zvakatemwa, inowanzoda kusvika 100%, ichisiya diki kana nzvimbo yekukanganisa kumucheto kwenzvimbo dzemaziso.

Saka sei uchipfuura nemumatambudziko ese aya?Mhinduro dzakapfuura dzaiwanzobatanidza mahombe ma subassemblies ezvakawanda zvekristaro zvikamu zvakabatanidzwa neNd: YAG bar.Izvi zvimwe zvikamu zvinogona kusanganisira Brewster mahwendefa, saturable absorbers for passive Q-switching, kana frequency conversion crystals.Frequency conversion crystals akakosha mu rangefinder kana mamwe maapplications emhepo akavhurika nekuti emission wavelength ye neodymium ine ngozi zvakanyanya pane erbium uye inofanirwa kuchinjirwa kune yakarebesa wavelength isati yakwanisa kutapuriranwa zvakachengetedzeka kwenhambo refu.
Rangefinder maapplications anowanzo kuve nekukatyamadzwa uye vibration chinodiwa, izvo zvinoita kuti kubatanidza akawanda mazvikamu pamwe chete uku kusangana zvese zvakatemwa zvakaoma.Kufamba kubva kune aya madhizaini kuenda kune imwechete, yakakwenenzverwa chidimbu cheEr: girazi rinoita mabasa mamwechete neakasiyana machira akaderedzwa saizi yehurongwa uye mutengo.YAG makristasi anowanzo shandiswa paBrewster's angle, asi zvakafanana zvinogona kuitwa nekushandisa machira.Sezvo Er: girazi slabs inoda kuvharwa zvakadaro, zvinobatsira kuwedzera mune iyi rudzi rwejasi kurongedza mukushanda kwakawanda sezvinobvira uye kuchengetedza mutengo kumwe kunhu.
Nekuti magirazi ephosphate ane hygroscopic zvishoma, kana asina kuvharwa Er: girazi rinosiiwa kunze kwemazuva akati wandei rinogona kukanganisa.Hunhu hwepamusoro hunofanirwa kudzorwa usati wapfekedzwa kudzivirira hunyoro kubva pakufamba mugirazi.Mabhachi akaiswa panzvimbo yakakwenenzverwa yegirazi rekupedzisira slab inobatsira kuvadzivirira kubva mukuora uku.
Matauriro akajairika kune madiki, epamusoro-chaiyo Er: magirazi slabs ari <5 arcmin perpendicularity kumapendero, <10 arcsec yeperpendicularity kune inogumira, uye yepamusoro yepamusoro iri nani kupfuura 10-5 scratch dig.Izvi zvinoda kutaurwa zvinoda nharaunda yakachena, maitiro anodzorwa zvakanyanya, uye yakaderedzwa yekubata nguva.
Laser girazi rinowanzo kungova nenzvimbo mbiri dzakakwenenzverwa pamigumo nepo mamwe ese ari pasi, asi mamwe mativi eiyi Er: girazi slabs zvakare yakakwenenzverwa uye inoshivirirwa zvakanyanya kurerutsa kurongeka.Sarudzo yekuti ndeapi mativi ekutanga kukwenenzverwa nekupfekedzwa, mativi ekuti akwenenzverwa pamberi kana mushure mekuita dhayi, uye nguva yekushandiswa kwedivi rimwe kana maviri-padivi polishing zvese zvinotarisa mutengo uye goho.Musiyano wegoho pakati pemaitiro asina ruzivo uye maitiro akagadziridzwa nemugadziri ane ruzivo anogona kuve akakura sechikamu chetatu.
Kuti uderedze nguva yekubata uye kugadzirisa goho, zvakaringana kuita kuti zvese zvekugadzira uye coating zviitwe panzvimbo imwechete.Nguva imwe neimwe chikamu chinopedzwa zvishoma chinotumirwa pakati penzvimbo dzakasiyana mukana wekusvibiswa uye kukuvara unowedzera zvakanyanya, pamwe nekuwedzera nguva yemutsetse.
MULTIPLE HIGH-LIDT COATINGS
Rimwe dambudziko nekugadzira diki Er: girazi slabs yekutsvagisa uye mamwe chaiwo maNIR maapplication nderekuti akawanda machira anowanzo kuisirwa pamativi akasiyana echikamu.Izvi zvakaoma nekuda kwekugadziriswa kunodiwa uye kuchengetedza kwepristine isina kuvharwa nzvimbo isati yapfeka.Izvo zvakare zvinonetsa kune vanogadzira kuti vadzivise overspray kana kuputika-nekuseri kwe slab, iyo inofanirwa kuchengetedzwa panguva yekupfeka.Migumo inoratidzira anti-reflective (AR) machira ane yakakwira lase-induced kukuvara zvikumbaridzo (LIDTs).Mipendero zvakare inoratidzira yakakwira LIDT AR coatings kuti ipinde mupombi danda.Simba repombi rinogara rakakwirira kudarika iro rekubuda.Mamwe mativi mana-slabs ane mamwe machira eakavakirwa-mu-high-reflectivity cavity magirazi, wavelength rusarura, uye kurambwa kwechiedza chepombi.
METROLOGY: KANA Usingakwanisi KUYERA HAUGONE KUITA
Kugadzira chaiko uye kutonga kwemaitiro hakuna zvakunobatsira pasina iyo metrology yakakodzera inodiwa kuyera nemazvo uye kuona zvakakosha zvakatemwa.Laser interferometers, yakadai seZYGO Verifier, inowanzoshandiswa kuyera flatness, asi pakuyera diki Er: girazi slabs nzvimbo yekumashure inotanga kuvhiringidza kuyerwa kwechiso chepamberi nekuda kwekuda kufananidzwa kweparallelism.Vashandi vanogona kutenderedza izvi nekuisa Vaseline kana chimwe chinhu kumashure, asi nzvimbo iyi inoda kucheneswa uye mukana wekukuvara kwechikamu unowedzera.Nekudaro, kufambira mberi kwechangobva kuitika mukuyera kweflatness kunobvisa mhedzisiro kubva kumashure kwepamusoro uye kubvumira kuyerwa kwe flatness kuti kuitwe nekukurumidza uye pasina mukana wekukuvara.Chips pamicheto ye slabs inogona kudzivirira vashandi kubva pakuyera kuyera flatness, izvo zvinoita kuti maitiro ekugadzirisa panguva yekugadzira atonyanya kukosha.Perpendicularity uye wedge zvinowanzosimbiswa uchishandisa kaviri pass autocollimator.
Iyo inokura yekushandisa nzvimbo yeEr: girazi lasers icharamba ichisundidzira optical component vagadziri kuti vagadzire yakakwirira uye yepamusoro chaiyo laser girazi uye machira.1540nm uye 1570nm ziso-yakachengeteka laser zvikumbiro zvinobatsira kuita kuti kushandiswa kuve kwakachengeteka, kuwedzera kusatya kuburikidza neaesthetic laser maitiro, uye kunatsiridza kutaurirana kureba.Zano rakanakisa riripo nderekuti kana uchigadzira NIR laser system;kurukura zvaunoda zvekushandisa nechikamu chako chemupi wekutungamira mukufambisa iyo nuanced sarudzo yeakakodzera laser girazi uye zvimwe zvinhu.
