Ulawulo lweqondo lokushisa lwe-TEC luqinisekisa ukuba ukusasazwa kusebenza kwiqondo eliphezulu lobushushu (ngokuqhelekileyo ~ 25 ° C) ukuphepha uluhlu lwamaza.

2. Inkqubo yengxelo yomgodi wangaphandle

I-Grating eqhubayo (i-Littrow okanye i-Littman-Metcalf uhlobo lwesakhiwo): isetyenziselwa ukukhethwa kwe-wavelength kunye nempendulo ye-single-frequency.

I-actuator ye-PZT: i-engile yokugaya i-grating yokufezekisa i-fiber ye-wavelength echanekileyo.

3. Ukwahlukaniswa kwe-Optical kunye nokulawula imodi

I-Faraday isolator: ikhusela ukukhanya okubuyayo ekuphazamiseni ukuzinza kwelaser.

Imowudi ehambelana netshathi: ilungisa umgangatho we-beam kwaye iqinisekisa imveliso yemodi ye-TEM00.

4. Inkqubo yolawulo lwe-elektroniki

I-drive yangoku yengxolo ephantsi: ibonelela ngokuzinzile kwempompo ye-LD yangoku.

Isekethe yokulawula ubushushu be-PID: lungisa ngokuchanekileyo ukusasazwa kwe-laser kunye nobushushu begrafti.

Imodyuli yokutshixa rhoqo (ukhetho): njenge-PDH ezinzileyo, esetyenziselwa izicelo zobubanzi obumxinwa kakhulu.

5. Ukudityaniswa kweziphumo kunye nokubeka iliso

Isipili esibonakalisa ngokuyinxenye: khupha i-laser ngelixa ugcina ingxelo ye-intracavity.

Ukujongwa kwe-Photodiode (PD): ukubonwa kwexesha langempela lamandla e-laser kunye nokuzinza kwemodi.

IV. Iimpazamo eziqhelekileyo kunye neengcamango zokulondoloza

1. Akukho mveliso yelaser okanye ukuhla kwamandla

Izizathu ezinokwenzeka:

Ukonakala kweLaser (ukuqhekeka kwe-ESD okanye ukuguga).

Ukusilela kwangoku ngokuqhuba (okufana nomonakalo wemodyuli yamandla).

Ukulungiswa kwegrafti (ukungcangcazela komatshini kubangela ukungaphumeleli kwengxelo).

Izimvo zogcino:

Khangela ukuba ngaba idrive yangoku iqhelekile (jonga kwixabiso lokucwangcisa ngesandla).

Sebenzisa imitha yamandla ukufumanisa ukuba i-LD ikhupha ukukhanya (ukhuseleko lokhuseleko luyafuneka).

Lungisa kwakhona i-angle yegrating ukuqinisekisa ingxelo yomgodi wangaphandle.

2. Ukungazinzi kobude okanye imowudi yokutsiba-tsiba

Izizathu ezinokwenzeka:

Ukusilela kolawulo lobushushu (TEC ukusilela okanye thermistor).

Ukukhululeka komatshini (i-PZT okanye i-grating ayilungiswanga ngokuqinileyo).

Ukungcangcazela kwangaphandle okanye ukuphazamiseka kokuphela.

Izimvo zogcino:

Jonga ukuba i-TEC iseti yobushushu iyahambelana na neqondo lokwenyani.

Iqonga le-collagen optical ukunciphisa ukungcangcazela kokusingqongileyo.

Sebenzisa imitha yobude bobude ukujonga kwaye umisele kwakhona ukuba kuyimfuneko.

I-Grating ibambekile ngoomatshini (i-lubrication engonelanga okanye i-structural deformation).

V. Amanyathelo okukhusela olondolozo

Ukucoca rhoqo amacandelo optical

Sebenzisa i-ethanol ene-anhydrous kunye ne-ultra-clean cotton swabs ukucoca i-grating kunye nesibuko esiphumayo ukuphepha ukuchaphazela ukuzinza kwemodi.

Ukuhlolwa kunye nokulawula ubushushu

Qinisekisa ukuba i-TEC ayinathuli kwaye ifeni iqhuba ngokuqhelekileyo.

Ukhuseleko oluchasayo (ESD)

Ulawulo lokusingqongileyo

Gcina iqondo lobushushu elingaguqukiyo (± 1°C) kunye nemekobume yokungcangcazela ephantsi, kwaye usebenzise iqonga lokuhlukanisa elibonayo xa kuyimfuneko.

Ukucwangciswa rhoqo

Sebenzisa imitha ye-wavelength kunye nemitha yamandla ukulungiselela imveliso ukuqinisekisa ukuzinza kwexesha elide.

VI. Ukuqukumbela

I-TopWave 405 ye-laser ye-frequency single-frequency, kunye nokuzinza kwayo kunye neempawu zobubanzi obumxinwa, lukhetho olufanelekileyo lophando lwezenzululwazi kunye nezicelo eziphezulu zemizi-mveliso. Ukugcinwa rhoqo, ukulawulwa kwendalo kunye neendlela ezichanekileyo zokuxilonga iimpazamo zingundoqo zokuqinisekisa ukusebenza kwayo okuthembekileyo kwexesha elide. Ngeengxaki ezintsonkothileyo (ezifana nokungaphumeleli kokutshixa i-frequency okanye umonakalo we-laser), kuyacetyiswa ukuba uqhagamshelane neqela lethu lobugcisa ukuze uphephe umonakalo ongakumbi obangelwa kukuchithwa kwefowuni.
