Spectra Physics Quasi Continuous Laser (QCW) Vanguard One UV125 ye layisi ya ultraviolet eya quasi-continuous ultraviolet ekola ebyuma ebituufu, ng’egatta amaanyi amangi agafuluma n’omutindo gwa bimuli omulungi ennyo. Wammanga y’ennyanjula ku nsengeka yaayo, ensobi ezitera okubaawo n’engeri y’okuddaabirizaamu:

1. Enzimba y’ebintu

Ekituli ekiwuuma kya layisi

Ensibuko y’ensigo: Ebiseera ebisinga kirisitaalo ya layisi ya Nd:YVO4 epambiddwa dayodi ekola ekitangaala kya 1064nm fundamental frequency.

Module ya Q-switching: Acousto-optic Q-switching (AO-Q switch) oba electro-optic Q-switching (EO-Q switch) okukola pulses ennyimpi.

Module y’okukubisaamu emirundi ebiri frequency: Ekyusa 1064nm okudda mu 532nm (second harmonic) okuyita mu KTP/LBO crystal, n’oluvannyuma okutuuka ku 355nm (third harmonic, ultraviolet output) okuyita mu BBO crystal.

Enkola y’okupampagira

Laser diode array: Ewa amaanyi ga pampu ku Nd:YVO4 crystal, nga kyetaagisa okufuga ebbugumu okutuufu (TEC cooling).

Okukola UV n’okufulumya

Ekibinja kya kirisitaalo ekitali kya linnya: kirisitaalo ya BBO oba CLBO ekozesebwa okukyusa UV, ekyetaaga okukuumibwa nga nnyonjo era nga ebbugumu linywevu.

Output coupling mirror: UV anti-reflection coating esiigibwa okukendeeza ku kufiirwa amaanyi.

Enkola y’okunyogoza

Module y’okunyogoza amazzi/okunyogoza empewo: Kuuma obutebenkevu bw’ebbugumu ly’omutwe gwa layisi, kirisitaalo ne dayodi (ebiseera ebisinga kyetaagisa obutuufu bw’ebbugumu ly’amazzi erya ±0.1°C).

Okufuga n’okugabira amasannyalaze

Amasannyalaze aga vvulovumenti eya waggulu: Drive Q-switching module ne pump diode.

Enkola y’okufuga: Nga mulimu PLC oba embedded controller, okuddukanya amaanyi, frequency, pulse width ne parameters endala.

Obukuumi bw’ekkubo ery’amaaso

Ekituli ekissiddwako: Kijjula nayitrojeni oba empewo enkalu okuziyiza ekitangaala kya UV okuleeta obucaafu bw’ebitundu by’amaaso (nga crystal deliquescence ne mirror oxidation).

2. Ensobi eza bulijjo n’ebiyinza okuvaako

Amaanyi gagwa oba tewali kufuluma

Obujama bw’ebitundu by’amaaso: Okwonooneka kwa UV crystal (BBO) oba okusiiga endabirwamu.

Q-switching okulemererwa: AO/EO-Q switch drive obutali bwa bulijjo oba crystal offset.

Pump diode aging: okukendeera kw’amaanyi agafuluma oba okulemererwa okufuga ebbugumu.

Okwonooneka kw’omutindo gw’ebikondo (okweyongera mu nkoona y’okuwukana, mode etali ya bulijjo) .

Resonant cavity misalignment: okukankana kw’ebyuma kuleeta lenzi okukyuka.

Crystal thermal lens effect: obutanyogoga bumala oba amaanyi agasukkiridde kireeta okukyukakyuka kwa crystal.

Okukendeeza ku bulungibwansi bw’okukyusa UV

Crystal phase matching angle offset: okukyukakyuka kw’ebbugumu oba okusumululwa kw’ebyuma.

Amaanyi agatali gamala ga kitangaala kya firikwensi ey’omusingi (1064nm/532nm): ekizibu ky’okukubisaamu firikwensi nga tekunnabaawo.

System alarm oba okuggalawo

Okulemererwa okunyogoza: ebbugumu ly’amazzi liri waggulu nnyo, okukulukuta tekumala oba sensa si ya bulijjo.

Amaanyi agasukkiridde: modulo ya vvulovumenti eya waggulu short circuit oba capacitor okukaddiwa.

Obutabeera mu ntebenkevu mu pulse (okukyukakyuka kw’amasoboza, emirundi gy’okuddiŋŋana mu ngeri etali ya bulijjo) .

Q switch drive signal interference: okukwatagana kwa cable okubi oba oluyoogaano lw’amasannyalaze.

Okufuga okulemererwa kwa pulogulaamu: ensobi mu kuteekawo parameter oba ekizibu kya firmware.

III. Ebipimo by’okuddaabiriza

Okukebera amaaso buli kiseera

Okwoza lenzi y’ekkubo ly’ekitangaala eky’ebweru (kozesa ethanol etaliimu mazzi n’olupapula lwa lenzi) era okebere oba kungulu kwa kirisitaalo ya UV eyonoonese oba eriko obucaafu.

Weetegereze: Weewale okukwatagana obutereevu n’ekizigo ky’amaaso, era obutafaali bwa UV (nga BBO) bwetaaga okuterekebwa mu ngeri etayingiramu bunnyogovu.

Okuddaabiriza enkola y’okunyogoza

Bulijjo kyusa amazzi agataliimu ayoni (okuziyiza okukutuka), kebera oba payipu ekulukuta, era oyoze enfuufu eri ku radiator.

Kaliba sensa y’ebbugumu okukakasa sipiidi y’okuddamu kw’enkola y’okunyogoza.

Amasannyalaze n’okukebera circuit

Londoola obutebenkevu bw’okufuluma kw’amasannyalaze aga vvulovumenti eya waggulu era okyuse capacitors oba ebitundu bya filter ebikaddiye.

Kebera layini ya grounding okukendeeza ku kutaataaganyizibwa kw’amasannyalaze.

Okupima ne Kozesa mita y’amaanyi n’ekipima ebikondo okupima amaanyi agafuluma n’embeera y’ekifo buli kiseera.

Okulongoosa Q-switching parameters (nga pulse width ne repetition frequency) okuyita mu software efugira.

Okufuga obutonde bw’ensi

Kuuma ebbugumu n’obunnyogovu obutakyukakyuka mu mbeera y’okukoleramu (ebbugumu erisemba 22±2°C, obunnyogovu <50%).

Singa ekyuma kiggalwa okumala ebbanga ddene, kirungi okujjuza ekkubo ly’amaaso nayitrojeni.

Okuwandiika ensobi n’okuziyiza

Wandiika koodi ya alamu n’ekikolwa ky’ensobi okusobola okwanguyiza ekifo ekizibu eky’amangu (nga pulogulaamu ya Spectra Physics etera okuwa ebiwandiiko by’ensobi).

IV. Okwegendereza

Obukuumi: Layisi ya Ultraviolet (355nm) ya bulabe eri olususu n’amaaso, era endabirwamu ez’enjawulo ezikuuma zirina okwambalibwa ng’okola.

Okuddaabiriza okw’ekikugu: Okulongoosa mu ngeri ya crystal n’okulongoosa mu kifo ekiwuuma (resonant cavity debugging) birina okukolebwa omukozi oba bayinginiya abakakasibwa okwewala okwekutula.

Enzirukanya ya sipeeya: Teeka ebitundu ebitali binywevu (nga O-rings, pump diodes, Q-switch crystals).

Singa kyetaagisa obuyambi obulala obw’ekikugu, kirungi okutuukirira ttiimu yaffe ey’ekikugu n’owaayo ennamba ya layisi n’ebikwata ku nsobi okufuna eby’okugonjoola ebigendereddwamu.
