I-Spectra Physics Quasi Continuous Laser (QCW) iVanguard One UV125 yilaser ye-ultraviolet ye-quasi-continuous machining ngokuchanekileyo, ukudibanisa ukuphuma kwamandla aphezulu kunye nomgangatho obalaseleyo we-beam. Oku kulandelayo sintshayelelo kulwakhiwo lwayo, iimpazamo eziqhelekileyo kunye nemilinganiselo yokulondoloza:

1. Isakhiwo

I-Laser resonant cavity

Umthombo wembewu: Ngokuqhelekileyo i-diode-pumped Nd:YVO₄ laser crystal evelisa ukukhanya okuzinzile kwe-1064nm.

Imodyuli yokutshintsha i-Q: I-Acousto-optic Q-switching (i-AO-Q switch) okanye i-electro-optic Q-switching (i-EO-Q switch) yokuvelisa iipulses ezimfutshane.

Imodyuli yokuphindaphinda ngokuphindaphindiweyo: Iguqula i-1064nm ukuya kwi-532nm (i-harmonic yesibini) ngekristale ye-KTP/LBO, kwaye emva koko ibe yi-355nm (i-harmonic yesithathu, i-ultraviolet output) nge-BBO crystal.

Inkqubo yokumpompa

I-Laser diode array: Ibonelela ngamandla epompo ye-Nd:YVO₄ crystal, ifuna ulawulo oluchanekileyo lobushushu (ukupholisa kwe-TEC).

Ukuveliswa kwe-UV kunye nemveliso

Iqela le-crystal elingenakulinganiswa: I-BBO okanye i-CLBO crystal isetyenziselwa ukuguqulwa kwe-UV, ekufuneka igcinwe icocekile kwaye iqondo lokushisa lizinzile.

Isibuko sokudibanisa imveliso: I-UV anti-reflection coating isetyenziselwa ukunciphisa ukulahleka kwamandla.

Inkqubo yokupholisa

Ukupholisa amanzi / imodyuli yokupholisa umoya: Gcina ukuzinza kobushushu bentloko ye-laser, ikristale kunye nediode (ngokuqhelekileyo ifuna ukuchaneka kobushushu bamanzi ± 0.1℃).

Ulawulo kunye nonikezelo lwamandla

Ukunikezelwa kwamandla ombane aphezulu: Qhuba imodyuli yokutshintsha i-Q kunye ne-diode yepompo.

Inkqubo yokulawula: Kubandakanya i-PLC okanye umlawuli odibeneyo, ukulawula amandla, ukuphindaphinda, ububanzi be-pulse kunye nezinye iiparameters.

Ukukhuselwa kwendlela yokubona

Umgodi otywiniweyo: Uzaliswe ngenitrogen okanye umoya owomileyo ukuthintela ukukhanya kwe-UV ekubangeleni ungcoliseko lwelungu lokukhanya (elifana nekristale deliquescence kunye ne-mirror oxidation).

2. Iimpazamo eziqhelekileyo kunye nezizathu ezinokwenzeka

Ukwehla kwamandla okanye akukho mveliso

Ungcoliseko lwecandelo le-Optical: Ikristale ye-UV (BBO) okanye umonakalo wesibuko sokugquma.

Ukungaphumeleli kokutshintsha kwe-Q: I-AO / EO-Q yokutshintsha i-drive engaqhelekanga okanye i-crystal offset.

Ukuguga kwePump diode: Ukucutha amandla okuphuma okanye ukusilela kolawulo lobushushu.

Ukuwohloka komgangatho we-beam (ukwanda kwe-engile yokuhlukana, indlela engaqhelekanga)

Ukungalungelelani kakuhle komngxunya weResonant: Ukungcangcazela koomatshini kubangela ukucinywa kwelensi.

I-Crystal thermal lens effect: ukupholisa okungonelanga okanye amandla agqithisileyo abangela ukuguqulwa kwekristale.

Ukunciphisa ukusebenza kakuhle kokuguqulwa kwe-UV

Isigaba seCrystal sokuthelekisa i-angle offset: ukuguquguquka kobushushu okanye ukukhululeka komatshini.

Amandla angonelanga okukhanya okuphindaphindiweyo okusisiseko (1064nm/532nm): ingxaki yokuphindaphinda kwangaphambi kwenqanaba.

I-alam yenkqubo okanye ukuvala

Ukungaphumeleli kokupholisa: ubushushu bamanzi buphezulu kakhulu, ukuhamba kwamanzi akwanelanga okanye inzwa ayiqhelekanga.

Ukugqithiswa kwamandla: imodyuli ephezulu yombane wesekethe emfutshane okanye ukuguga kwe-capacitor.

Ukungazinzi kwePulse (ukuguquguquka kwamandla, ukuphindaphinda okungaqhelekanga)

Ukuphazamiseka kophawu lwe-Q switch drive: unxibelelwano lwentambo embi okanye ingxolo yombane.

Lawula ukusilela kwesoftware: impazamo yolungiselelo lweparamitha okanye bug firmware.

III. Amanyathelo okugcina

Ukuhlolwa rhoqo kwamehlo

Coca i-lens yendlela yokukhanya yangaphandle (sebenzisa i-ethanol e-anhydrous kunye nephepha le-lens) kwaye ukhangele ukuba umphezulu we-UV crystal wonakalisiwe okanye ungcolisekile.

Qaphela: Kuphephe ukudibana ngokuthe ngqo ne-optical coating, kunye neekristale ze-UV (ezifana ne-BBO) kufuneka zigcinwe ngendlela yobungqina bokufuma.

Ukugcinwa kwenkqubo yokupholisa

Rhoqo tshintsha amanzi adiyiniweyo (ukuthintela isikali), khangela ukuba umbhobho uyavuza, kwaye ucoce uthuli kwirediyetha.

Ukulinganisa inzwa yobushushu ukuqinisekisa isantya sokuphendula senkqubo yokupholisa.

Ubonelelo lwamandla kunye nokuhlolwa kwesekethe

Beka esweni ukuzinza kwemveliso yonikezelo lwamandla aphezulu-voltage kwaye ubuyisele ii-capacitors zokuguga okanye amacandelo okucoca.

Jonga umgca wokumisa ukuze unciphise ukuphazamiseka kwe-electromagnetic.

Ukulinganisa kunye nokuSebenzisa imitha yamandla kunye ne-analyzer ye-beam ukulinganisa amandla emveliso kunye nemodi yebala rhoqo.

Lungiselela i-Q-switching parameters (ezifana nobubanzi be-pulse kunye nokuphindaphinda rhoqo) ngokusebenzisa isofthiwe yokulawula.

Ulawulo lokusingqongileyo

Gcina ubushushu obungaguqukiyo kunye nokufuma kwindawo yokusebenza (ubushushu obucetyiswayo ngu-22±2℃, ukufuma <50%).

Ukuba umatshini uvaliwe ixesha elide, kucetyiswa ukuba ugcwalise indlela ye-optical kunye ne-nitrogen.

Ukurekhoda iimpazamo kunye nokuthintela

Rekhoda ikhowudi yesivusi kunye nempazamo ukwenza lula indawo yengxaki ekhawulezayo (efana neSpectra Physics software ihlala ibonelela ngeempazamo zelogi).

IV. Ukulumkela

Ukukhuselwa koKhuseleko: I-Ultraviolet laser (355nm) inobungozi esikhumbeni kunye namehlo, kwaye iiglasi ezikhethekileyo zokukhusela kufuneka zifakwe ngexesha lokusebenza.

Ulondolozo lobuchwephesha: Ukulungelelaniswa kwekristale kunye nokulungiswa kwe-resonant cavity kufuneka kwenziwe ngumenzi okanye iinjineli eziqinisekisiweyo ukunqanda ukuziqhawula.

Ulawulo lwamalungu asetyenzisiweyo: Gcina iindawo ezisesichengeni (ezifana ne-O-rings, i-pump diode, iikristale ze-Q-switch).

Ukuba inkxaso eyongezelelweyo yobugcisa iyafuneka, kuyacetyiswa ukuba uqhagamshelane neqela lethu lobugcisa kwaye unikeze inombolo ye-laser ye-serial kunye neenkcukacha zephutha ukufumana izisombululo ezijoliswe kuzo.
