Rofin Inganda zikomeye za Leta Laser gusana

SLS ya Rofin (ubu ni Coherent) SLS ikurikirana-ikoresha lazeri ikoresha tekinoroji ya diode-pompe ikomeye ya laser (DPSSL) kandi ikoreshwa cyane mugutunganya inganda (nko gushiraho ikimenyetso, gukata, gusudira) nubushakashatsi bwa siyanse. Uru ruhererekane rwa laseri ruzwiho guhagarara neza, kuramba no kuramba kwiza (M²), ariko birashobora kunanirwa nyuma yo gukoresha igihe kirekire, bigira ingaruka kumikorere.

Iyi ngingo izerekana imiterere, amakosa asanzwe, ibitekerezo byo kubungabunga, gufata neza buri munsi ningamba zo gukumira urukurikirane rwa SLS muburyo burambuye kugirango bafashe abakoresha kongera ubuzima bwibikoresho no kugabanya igihe cyo gutaha.

2. SLS ikurikirana ya laser imiterere

Urutonde rwa SLS rugizwe ahanini nuburyo bukurikira:

1. Umutwe wa Laser

Laser kristal: mubisanzwe Nd: YAG cyangwa Nd: YVO₄, yapompe na diode ya laser.

Q-guhinduranya module (Q-Hindura):

Acousto-optique Q-switch (AO-QS): ikwiranye nigipimo kinini cyo gusubiramo (urwego rwa kHz).

Electro-optique Q-switch (EO-QS): ikwiranye ningufu zingufu nyinshi (nka micromachining).

Inshuro ebyiri inshuro ebyiri (SHG / THG) (bidashoboka):

KTP (532nm itara ryatsi) cyangwa BBO (355nm UV itara) kugirango uhindure uburebure.

2. Moderi ya pompe ya diode

Laser diode array (LDA): Itanga urumuri rwa pompe 808nm, bisaba kugenzura ubushyuhe bwa TEC kugirango ibungabunge umutekano.

Sisitemu yo kugenzura ubushyuhe (TEC): Iremeza ko diode ikora ku bushyuhe bwiza (ubusanzwe 20-25 ° C).

3. Sisitemu yo gukonjesha

Gukonjesha amazi (Chiller): Imbaraga zikomeye (nka SLS 500+) zisaba ubukonje bwo hanze kugirango ubushyuhe bwumutwe wa laser buhamye.

Gukonjesha ikirere (Air Cooling): Moderi nkeya irashobora gukoresha gukonjesha ikirere ku gahato.

4. Sisitemu ya optique (Gutanga ibiti)

Kwagura ibiti (Kwagura urumuri): Hindura diameter.

Indorerwamo (HR / OC Indorerwamo): Indorerwamo zerekana cyane (HR) hamwe nindorerwamo zisohoka (OC).

Optical isolator (Optical Isolator): Irinda kugaruka kumuri kwangiza laser.

5. Kugenzura no gutanga amashanyarazi

Gutwara amashanyarazi: Tanga ibimenyetso bihamye kandi byerekana modulasi.

Igenzura / porogaramu: Hindura ibipimo nkimbaraga, inshuro, ubugari bwa pulse, nibindi.

III. Amakosa asanzwe hamwe nibitekerezo byo kubungabunga

1. Nta bisohoka bya laser cyangwa kugabanya ingufu

Impamvu zishoboka:

Laser diode gusaza cyangwa kwangirika (ubuzima rusange bumara amasaha 20.000-50.000).

Q guhinduranya module kunanirwa (AO-QS gutsindwa cyangwa gutsindira kristu).

Sisitemu yo gukonjesha (ubushyuhe bwamazi ni hejuru cyane cyangwa gutemba ntibihagije).

Uburyo bwo gufata neza:

Reba niba LD iriho isanzwe (reba igitabo cya tekiniki).

Reba niba itara rya pompe risanzwe hamwe na metero yingufu.

Reba ibimenyetso bya Q uhinduranya hanyuma usimbuze AO / EO-QS nibiba ngombwa.

2. Kwangirika kwubwiza bwibiti (uburyo budahungabana, guhindura ibintu)

Impamvu zishoboka:

Ibikoresho byanduye byanduye (lens yanduye nubuso bwa kirisiti).

Resonant cavity kudahuza (vibrasiya itera lens displacement).

Ingaruka yubushyuhe bwa Crystal (deformasiyo yubushyuhe iterwa no gukonja bidahagije).

Uburyo bwo gusana:

Sukura ibice bya optique (koresha etanol ya anhydrous + imyenda idafite ivumbi).

Ongera usubire mu cyuho cya resonant (bisaba ibikoresho byumwuga nka He-Ne laser collimator).

3. Guhinduranya umuraba cyangwa inshuro ebyiri kugabanya imikorere

Impamvu zishoboka:

Gukuba inshuro ebyiri kristu (KTP / BBO) kugabanuka kwubushyuhe cyangwa icyiciro gihuza inguni ihinduka.

Impinduka yumurongo wa pompe (kunanirwa kugenzura ubushyuhe bwa TEC).

Uburyo bwo gusana:

Ongera uhindure inguni ya kristu (koresha ikadiri yo kugenzura neza).

Reba niba kugenzura ubushyuhe bwa TEC bihamye (Guhindura ibipimo bya PID).

4. Impuruza kenshi cyangwa guhagarika byikora

Impamvu zishoboka:

Kurinda kurenza urugero (gukonjesha sisitemu kunanirwa).

Amashanyarazi arenze urugero (capacitor gusaza cyangwa umuzunguruko mugufi).

Kugenzura amakosa ya software (ukeneye kuzamura software).

Uburyo bwo gusana:

Reba amazi akonje atemba hamwe nubushyuhe bwubushyuhe.

Gupima niba amashanyarazi asohoka voltage ihagaze.

Menyesha uwabikoze kugirango ubone porogaramu zigezweho.

IV. Uburyo bwo kwita no kubungabunga buri munsi

1. Kubungabunga sisitemu nziza

Igenzura rya buri cyumweru:

Sukura indorerwamo isohoka na Q-guhinduranya idirishya hamwe na etanol ya anhydrous + ipamba idafite ivumbi.

Reba niba inzira nziza ihari (reba niba urumuri ruri hagati).

Buri mezi 3:

Reba niba inshuro ebyiri kristu (KTP / BBO) yangiritse cyangwa yanduye.

Hindura imyenge ya resonant (koresha ubufasha bwa lazeri nibiba ngombwa).

2. Kubungabunga sisitemu yo gukonjesha

Igenzura rya buri kwezi:

Simbuza amazi yimana (kugirango wirinde igipimo gifunga umuyoboro).

Sukura akayunguruzo kugirango ushushe neza.

Buri mezi 6:

Reba niba pompe yamazi ari ibisanzwe hanyuma upime umuvuduko (≥4 L / min).

Hindura ibyuma byerekana ubushyuhe (ikosa <± 0.5 ° C).

3. Kubungabunga sisitemu ya elegitoroniki

Igenzura buri gihembwe:

Gupima amashanyarazi asohoka ahamye (ihindagurika ryubu <1%).

Reba niba guhagarara ari byiza (irinde kwivanga kwa electronique).

Kubungabunga buri mwaka:

Simbuza gusaza ubushobozi (cyane cyane igice kinini cyo gutanga amashanyarazi).

Wibike ibipimo byo kugenzura kugirango wirinde gutakaza amakuru
