GW Nanosecond pulsed ikomeye-ya laser yo gusana

GW YLPN-1.8-2 500-200-F ni lazeri isobanutse neza ya nanosekondi ngufi ya pulse (DPSS, diode-pompe ikomeye-laser) yakozwe na GWU-Lasertechnik (ubu ni igice cyitsinda rya Laser Component) mubudage. Irakoreshwa cyane muri:

Micromachining yinganda (gucukura PCB, gukata ibirahuri)

Ubushakashatsi bwa siyansi yubushakashatsi (isesengura ryerekana, laser-iterwa no gusenyuka LIBS)

Ubwiza bwubuvuzi (kuvanaho pigmentation, kubaga byibuze).

Ibipimo fatizo:

Uburebure: 532nm (itara ry'icyatsi) cyangwa 355nm (ultraviolet)

Ubugari bwa pulse: 1.8 ~ 2ns

Gusubiramo inshuro: 500Hz ~ 200kHz irashobora guhinduka

Imbaraga zo hejuru: ingufu nyinshi, zikwiranye no gutunganya neza.

2. Uburyo bwo kubungabunga buri munsi

(1) Kubungabunga sisitemu nziza

Igenzura rya buri cyumweru:

Koresha umukungugu udafite ivumbi kugirango usukure idirishya risohoka na ecran.

Reba guhuza inzira ya optique (kugirango wirinde gutandukana guterwa no kunyeganyega).

Igihembwe cyimbitse kubungabunga:

Koresha optique isukuye idasanzwe + idafite ipamba yo guhanagura lens (ntukoreshe inzoga kugirango wirinde kwangirika).

Menya ihererekanyabubasha rya laser kristal (nka Nd: YVO₄) hanyuma uyisimbuze nibiba ngombwa.

(2) Ubuyobozi bukonje

Kubungabunga ubukonje:

Koresha amazi ya deionised + anti-ruswa, usimbuze buri mezi 6.

Reba kashe yumuyoboro wamazi kugirango wirinde kumeneka.

Isuku ya radiator:

Sukura umukungugu hejuru yubushyuhe bukonjesha ikirere buri mezi 3 (kugirango ubushyuhe bugabanuke).

(3) Igenzura ry'amashanyarazi na mashini

Amashanyarazi ahamye:

Kurikirana iyinjizwa rya voltage ihindagurika (ukeneye <± 5%), birasabwa guha ibikoresho hamwe na UPS voltage stabilisateur.

Reba niba pompe diode (LD) igendanwa isanzwe.

Kugenzura ibidukikije:

Gukoresha ubushyuhe 15 ~ 25 ° C, ubuhehere <60%, irinde kwiyegeranya.

3. Amakosa asanzwe hamwe no gusuzuma

(1) Laser isohoka imbaraga ziragabanuka

Impamvu zishoboka:

Lens optique yanduye cyangwa yangiritse

Laser kristal (Nd: YVO₄ / YAG) gusaza cyangwa ingaruka zumuriro

Pompe diode (LD) imikorere iragabanuka.

Intambwe zo gusuzuma:

Koresha metero yimbaraga kugirango umenye ingufu zisohoka.

Reba inzira ya optique mubice (gutandukanya akavuyo ka resonant hanyuma ugerageze imikorere ya module imwe).

(2) Guhagarika umutima cyangwa kubura

Impamvu zishoboka:

Q hindura (nka acousto-optic modulator AOM) gutsindwa kwimodoka

Igenzura ryumuzunguruko (nkibibaho byigihe cya FPGA) ibimenyetso bidasanzwe

Amashanyarazi module amashanyarazi ntabwo ahagije.

Intambwe zo gusuzuma:

Koresha oscilloscope kugirango umenye ibimenyetso bya Q switch.

Reba niba igenamigambi risubiramo rirenze imipaka.

(3) Impuruza ya sisitemu

Impamvu zishoboka:

Amazi akonje adahagije (kunanirwa pompe yamazi cyangwa guhagarika imiyoboro)

Kunanirwa kwa TEC (thermoelectric cooler)

Ubushyuhe bwa sensor drift.

Intambwe zo gusuzuma:

Reba urwego rw'amazi hanyuma uyungurure.

Gupima niba voltage hejuru ya TEC ari ibisanzwe.

(4) Igikoresho ntigishobora gutangira

Impamvu zishoboka:

Amashanyarazi nyamukuru yangiritse (fuse irahuha)

Guhuza umutekano biraterwa (nka chassis ntabwo ifunze)

Kugenzura ikosa ryitumanaho rya software.

Intambwe zo gusuzuma:

Reba imbaraga zinjiza na fuse.

Ongera utangire software hanyuma usubiremo umushoferi.

4. Gusana ibitekerezo n'inzira

(1) Gukemura ibibazo bisanzwe

Igice cyiza:

Sukura cyangwa usimbuze lens yanduye → Ongera uhindure inzira nziza.

Igice cya elegitoroniki:

Simbuza ibyangiritse Q byahinduye ibiyobora → Hindura igihe cya pulse.

Igice gikonje:

Kuraho umuyoboro wahagaritswe → Simbuza pompe y'amazi / TEC.

(2) Guhindura no kugerageza

Kumenya impiswi: Koresha Photodetector yihuta + oscilloscope kugirango ugenzure ubugari bwa pulse nuburinganire.

Isesengura ryiza ryibiti: Koresha M² metero kugirango umenye neza ko impande zinyuranye zujuje ubuziranenge.

(3) Ibyifuzo byo guhitamo ibice

Ibice byumwimerere (nka LD modules na Q byahinduwe na GWU / Laser Ibigize) birahitamo.

Ubundi buryo: bihujwe cyane nigice cya gatatu cyibikoresho (guhuza ibipimo bigomba kugenzurwa).

5. Gahunda yo kubungabunga ibidukikije

Ukwezi: andika ibisohoka imbaraga na pulse ibipimo bigenda.

Buri mezi atandatu: optique cavity calibration na injeniyeri wabigize umwuga.

Buri mwaka: igenzura ryuzuye rya sisitemu yo gukonjesha hamwe nimbaraga zo gusaza.

Isubiramo

Binyuze mubikorwa bisanzwe bya buri munsi + ibitekerezo byo kubungabunga modular, ubuzima bwa laseri ya YLPN burashobora kwagurwa cyane kandi igihe cyo kugabanuka gishobora kugabanuka. Niba ukeneye inkunga yimbitse, nyamuneka nyamuneka hamagara itsinda ryacu rya tekiniki
