Kungani amandla e-laser ebola?

Ukuncipha kwamandla e-laser kuyinto evamile, okuvame ukuba umphumela wezinto ezahlukahlukene. Lezi zimbangela zingahlukaniswa ngezigaba ezimbili ezibanzi: ukuncipha okungenakugwenywa okungokwemvelo kanye nezici zangaphandle ezingancishiswa noma zigwenywe. Okulandelayo yizimbangela eziyinhloko zokubola kwamandla e-laser, ezihlelwe kusukela ekuqaleni kuya kwesibili:

Ukuguga kanye nomonakalo (ukuncipha kwemvelo) kwezingxenye ze-laser core

Lena imbangela eyinhloko yokubola kwamandla, ikakhulukazi kuma-laser anamandla amakhulu.

1. Ukunciphisa umthombo wephampu (uma kuthathwa i-semiconductor laser LD njengesibonelo)

Isimiso sokusebenza:I-LD “iyinjini” yama-laser amaningi e-solid-state kanye nama-fiber lasers “.

Indlela yokunciphisa:

Ukukhula okuphelele: Amaphutha e-lattice ngaphakathi kwe-chip ye-LD azoqhubeka nokukhula futhi aphindaphindeke ngaphansi kokucindezeleka kukagesi nokushisa kwesikhathi eside, okuholela ekwandeni kokuhlanganiswa kabusha okungenamisebe kanye nokwehla kokusebenza kahle kokuguqulwa kwe-electro-optical.

Umonakalo omkhulu wobuso bomgodi:Ngaphansi kwamandla aphezulu kakhulu, ukungcola okuncane noma amaphutha ebusweni bomgodi ophumayo kuzomunca ukukhanya kwe-laser, okubangela ukushisa kwendawo futhi kubangele ukuncibilika kobuso bomgodi, okuyinqubo engenakuguqulwa yokuwa kweqhwa.

Ukuwohloka kwe-electrode metallization:ukuthintana phakathi kwe-electrode nezinto ze-semiconductor kuzosakazwa phakathi kwe-metallic kanye ne-oxidation ekushiseni okuphezulu, okuholela ekumelaneni okukhulu kokuthintana kanye nokushisa okukhulu.

Ukusebenza:Umkhawulo wamandla womthombo wephampu uzokhula kancane kancane, futhi ukusebenza kahle kwe-slope kuzoncipha, okuholela ekwehleni kwamandla okukhipha.

2. Thola ukwehla kokusebenza okuphakathi

Ama-laser aqinile/ayifayibha (isib. i-YAG, amakristalu e-YV04, ifayibha ehlanganisiwe ye-Yb/Er):

Ukwakheka kwesikhungo sombala:Ngaphansi kokukhanya kwepompo okuhlala isikhathi eside (ikakhulukazi i-ult

izingxenye ze-raviolet), “izikhungo zombala” (izikhungo zokumunca) zizokhiqizwa ngaphakathi kwefayibha yekristalu noma yengilazi. La ma-core ombala amunca ukukhanya kwephampu kanye nokukhanya kwe-laser okukhiqizwayo, akuguqule kube amandla okushisa esikhundleni sokusetshenziselwa imisebe evuselelwe.

Umphumela welensi yokushisa kanye nomonakalo wokucindezeleka kokushisa:Nakuba umphumela welensi yokushisa ngokwawo ungaguqulwa, ukujikeleza kwezinga lokushisa okunamandla kwesikhathi eside kanye nokucindezeleka kokushisa kungabangela ukuqhekeka okuncane kukristalu, izinguquko ezihlala njalo ku-refractive index, noma ukufiphala kwefayibha.

I-laser yegesi (njenge-laser ye-co2):Ingxube yegesi izobola kancane kancane, imuncwe yi-electrode noma isabela ngezinto ezingaphakathi zodonga lwepayipi, okuholela ekungalinganini kwesilinganiso segesi esisebenzayo kanye nokwehla kwenzuzo.

3. Umonakalo wezinto ezibonakalayo

Ilensi/ifasitela elinomgodi ocwebezelayo:isibuko esigcwele, isibuko esiphumayo kanye nefasitela ngaphakathi kwe-laser yizindawo lapho amandla egxile khona kakhulu.

Umonakalo wefilimu:I-laser enamandla aphezulu izokwenza ilensi efilimu elwa nokukhanya noma i-anti-film ablation ephezulu, iqhekeke noma ivalwe.

Ukungcola:Izinto ezincane eziphilayo endaweni ezungezile (njengomusi kawoyela) zizonamathela ebusweni belensi, zifakwe i-carbon ngaphansi kwesenzo se-laser, zakha indawo yokumunca unomphela, okubangela umonakalo owengeziwe.

Ukumuncwa kwezinto:Ngisho nezinto ezibonakalayo zekhwalithi ephezulu zinokumuncwa okuncane kwangaphakathi kokukhanya kwe-laser kubude be-wavelength ethile. Imiphumela yesikhathi eside ingaholela ezinguqukweni ezisheshayo ezakhiweni zezinto ezibonakalayo.

Izimo zangaphandle zokusetshenziswa kanye nokusebenza okungafanele

Lezi zici zingasheshisa kakhulu inqubo yokuguga kwezingxenye eziyinhloko ezichazwe ngenhla.

1. Ukwehluleka kokuphathwa kokushisa

Ukusebenza kahle kohlelo lokupholisa kwehla:ikhwalithi yamanzi okupholisa iyawohloka futhi ibangele ukuthi umzila wamanzi ukhule futhi uvale; ukwehluleka kwesibandisi samanzi kubangela ukuthi izinga lokushisa lamanzi lingazinzile noma liphakame kakhulu; uthuli olufakwa kufeni lubangela ukushabalaliswa kokushisa okubi.

Imiphumela:Ukwanda kwezinga lokushisa lokusebenza kwe-laser kuzosheshisa kakhulu izinga lokuguga kwawo wonke ama-semiconductor kanye nezingxenye ze-optical. Ku-LD, isikhathi sokuphila singancishiswa ngesigamu ngokwanda ngakunye kokushisa kwe-junction okungu-10°C (kulandela imodeli ye-Arrhenius).

2. Indawo yokusebenza kanye nokungcola

Uthuli kanye nokungcola:uthuli, intuthu, uwoyela, njll. emoyeni kungena ku-laser, okuzongcolisa ubuso be-optical kanye ne-circuit, okubangela ukumuncwa kokushisa kwendawo, i-short circuit noma i-arc.

Ukudlidliza kanye nokushaqeka:Isisekelo sokufakwa esingazinzile noma ukudlidliza kwangaphandle kuzokwenza ukuthi ukuhambisana kwezingxenye ze-optical kuphambuke esimweni esifanele, kunciphise ukusebenza kahle kokukhipha, futhi kungabangela ukuthi isakhiwo semishini sikhululeke ezimweni ezinzima.

Umswakama:Umswakama owedlulele uzobangela ukujiya ebusweni belensi, okungabangela kalula ukuthi ifilimu iqhume ngaphansi kokukhanya kwe-laser. Ngesikhathi esifanayo, umswakama ungalimaza izingxenye ze-elekthronikhi.

3. Imodi yokusebenza engafanele

Ukushintsha okunzima okuvamile:Ukuvula nokuvala i-laser ngokugcwele njalo kuzoletha umthelela omkhulu kagesi nokushisa emthonjeni wephampu kanye nohlelo lwamandla, kufinyeze impilo yayo.

Ukusebenza kwesikhathi eside ngaphansi kwemingcele yomkhawulo:Vumela i-laser iqhubeke isebenza ngamandla angaphezu kuka-90% noma ngisho nokulayisha ngokweqile, okuzokwenza izingxenye zayo eziyinhloko zibe sesimweni sokucindezeleka okuphezulu futhi kusheshise ukuguga.

Imithwalo Engalingani:Kwezinye izinhlobo zama-laser, ukungalingani kokukhanya komthwalo kungabangela ukuthi amanye amandla abonakale emuva emgodini, okubangela ukungazinzi noma ngisho nomonakalo.

Ukuwohloka kwamandla nezinhlelo zokulawula

Ukusebenza kokunikezwa kwamandla edrayivu kuyehla:ukuzinza kwamandla kagesi/i-voltage yokukhipha amandla kuba kubi kakhulu, futhi i-ripple iyanda, engakwazi ukunikeza idrayivu eqinile nehlanzekile yomthombo wephampu, okuthinta ukusebenza kwayo nokuphila kwayo.

Ukuguga kwesekethe yokulawula:Amapharamitha ama-capacitor, ama-resistor nezinye izingxenye ahamba ngokuhamba kwesikhathi kanye nokushisa, okuholela ekunciphiseni ukunemba kohlelo lokulawula.

Isifinyezo kanye nezinyathelo zokuvimbela

Ukubola kwamandla kwe-laser kuyinqubo engenakugwema ngokuphelele kodwa engaphathwa kahle futhi yehliswe ijubane.

Ukuze kubambezeleke ukubola kwamandla ngezinga elikhulu futhi kugcinwe ukusebenza okuzinzile kwe-laser, kunconywa ukuthi:

1. Nikeza indawo yokusebenza enhle kakhulu:gcina uhlanzekile, izinga lokushisa elihlala linjalo, umswakama ophansi, akukho ukudlidliza.

2. Qinisekisa ukuphathwa kahle kokushisa:gcina uhlelo lokupholisa njalo ukuqinisekisa ikhwalithi yamanzi kanye nokugeleza kwawo.

3. Landela inqubo yokusebenza ejwayelekile:gwema ukushintsha njalo nokusebenza isikhathi eside ngaphansi kwezimo ezimbi kakhulu.

4. Yenza ukulungiswa okuvamile kokuvimbela:hlola njalo izingxenye ze-optical, hlanza indlela ye-optical, bese ushintsha izinto ezisetshenziswayo (njengegesi nezinto zokuhlunga) ngokwezidingo zomenzi.

5. Sebenzisa ugesi ozinzile:qinisekisa ukuthi i-voltage yokunikezwa kwamandla izinzile, bese usebenzisa i-voltage stabilizer uma kudingeka.

Ngokuqonda lezi zindlela zokunciphisa nokuthatha izinyathelo zokuphepha ezifanele, impilo ye-laser ingandiswa kakhulu futhi ukusebenza komkhiqizo okugcinwe phakathi nomjikelezo wokuphila kuzinzile kakhudlwana.
