Kutheni amandla e-laser ebola?

Ukuncitshiswa kwamandla elaser yinto eqhelekileyo, edla ngokuba yimiphumo yezinto ezahlukeneyo. Ezi zizathu zinokwahlulwa zibe ziindidi ezimbini ezibanzi: ukuncitshiswa okungenakuphepheka kunye nezinto zangaphandle ezinokucothiswa okanye ziphetshwe. Ezi zilandelayo zezona zizathu ziphambili zokubola kwamandla elaser, ezicwangciswe ukusuka kwisiseko ukuya kwesesibini:

Ukwaluphala kunye nomonakalo (ukuncitshiswa kwendalo) kwezixhobo ezingundoqo ze-laser

Le yeyona nto ibangela ukubola kwamandla, ingakumbi kwiilaser ezinamandla aphezulu.

1. Ukunciphisa umthombo wepompo (ukuthatha umzekelo we-semiconductor laser LD)

Umgaqo wokusebenza:I-LD "yinjini" yee-laser ezininzi ze-solid-state kunye nee-fiber lasers ".

Indlela yokunciphisa:

Ukukhula okugqibeleleyo: Iziphene zelattice ngaphakathi kwi-LD chip ziya kuqhubeka zikhula kwaye ziphindaphindeka phantsi koxinzelelo lombane kunye nobushushu bexesha elide, nto leyo ekhokelela ekwandeni kokuhlanganiswa kwakhona kwe-non-radiative kunye nokwehla kokusebenza kokuguqulwa kwe-electro-optical.

Umonakalo omkhulu womphezulu womngxuma obonakalayo:Xa amandla exinene kakhulu, ungcoliseko oluncinci okanye iziphene zomphezulu womngxuma ophumayo ziya kutsala ukukhanya kwelaser, nto leyo ebangela ukufudumeza kwendawo kwaye ibangele ukunyibilika komphezulu womngxuma, nto leyo eyinkqubo engenakuguqulwa yokuqhekeka kwentaba-mlilo.

Ukuchithwa kwe-electrode metallization:uqhagamshelwano phakathi kwe-electrode kunye nezinto ze-semiconductor luya kusasazeka phakathi kwe-metallic kunye ne-oxidation kubushushu obuphezulu, nto leyo ekhokelela ekunyukeni kokumelana noqhagamshelwano kunye nokufudumeza okukhulu.

Ukusebenza:Umda womsinga womthombo wepompo uya kwanda kancinci kancinci, kwaye ukusebenza kakuhle kwethambeka kuya kuncipha, nto leyo ebangela ukwehla kwamandla okukhupha.

2. Fumana ukuwohloka kokusebenza okuphakathi

Iilaser eziqinileyo/zefayibha (umz. iYAG, iikristale zeYV04, ifayibha exutywe neYb/Er):

Ukwakheka kombala embindini:Phantsi kokukhanya kwepompo okuhlala ixesha elide (ingakumbi ukukhanya okukhulu)

Izinto ze-raviolet), “iziko zombala” (iziko zokufunxa) ziya kuveliswa ngaphakathi kwifayibha yekristale okanye yeglasi. Ezi cores zombala zifunxa ukukhanya kwepompo kunye nokukhanya kwelaser okuvelisiweyo, ziguqula zibe ngamandla obushushu endaweni yokuba zisetyenziselwe imitha evuselelweyo.

Isiphumo seelensi yobushushu kunye nomonakalo woxinzelelo lobushushu:Nangona isiphumo selensi yobushushu ngokwaso sinokuguqulwa, ukujikeleza kobushushu okunzima kwexesha elide kunye noxinzelelo lobushushu kunokubangela ukuqhekeka okuncinci kwikristale, utshintsho oluhlala luhleli kwisalathiso sokurhawuzelela, okanye ukuba mnyama kwefayibha.

Ileyiza yegesi (njengeleyiza ye-CO2):Umxube wegesi uya kubola kancinci kancinci, ufunxwe yi-electrode okanye udibane nezinto ezingaphakathi eludongeni lwetyhubhu, nto leyo ebangela ukungalingani komlinganiselo wegesi esebenzayo kunye nokuncipha kwenzuzo.

3. Umonakalo wezinto ezibonakalayo

Ilensi/ifestile enomngxuma ocacileyo:isibuko esipheleleyo, isibuko esiphumayo kunye nefestile engaphakathi kweleza zezona ndawo apho amandla agxininise khona kakhulu.

Umonakalo wefilimu:I-laser enamandla aphezulu iya kwenza ilensi kwifilimu echasene nokukhanya okanye i-anti-film ablation ephezulu, iqhekeke okanye icime.

Ungcoliseko:Izinto ezincinci eziphilayo ezikwindalo esingqongileyo (ezifana nomphunga weoyile) ziya kunamathela kumphezulu welensi, zifakwe i-carbon phantsi kwesenzo se-laser, zenze indawo yokufunxa esisigxina, nto leyo ebangela umonakalo ongakumbi.

Ukufunxwa kwezinto:Kwanezixhobo ze-optical ezikumgangatho ophezulu zinokufunxwa okuncinci kokukhanya kwe-laser kwinqanaba elithile lobude bexesha. Iziphumo zexesha elide zinokukhokelela kutshintsho olucothayo kwiimpawu zezinto.

Iimeko zangaphandle zokusetyenziswa kunye nokusebenza okungafanelekanga

Ezi zinto zinokukhawulezisa kakhulu inkqubo yokwaluphala kwezinto eziphambili ezichazwe apha ngasentla.

1. Ukusilela kolawulo lobushushu

Ukusebenza kakuhle kwenkqubo yokupholisa kuncipha:Umgangatho wamanzi okupholisa uyawohloka kwaye ubangela ukuba umzila wamanzi unyuke kwaye uvale; ukungasebenzi kakuhle kwesixhobo sokupholisa amanzi kubangela ukuba ubushushu bamanzi bungaguquki okanye buphakame kakhulu; uthuli oluhlala kwifeni lubangela ukungabikho kobushushu obufanelekileyo.

Iziphumo:Ukwanda kobushushu bokusebenza kwelaser kuya kukhawulezisa kakhulu izinga lokwaluphala kwazo zonke ii-semiconductors kunye nee-optical components. Kwi-LD, ixesha lokuphila linokuncipha ngesiqingatha xa kunyuke i-10°C kubushushu be-junction (kulandela imodeli ye-Arrhenius).

2. Indawo yokusebenza kunye nongcoliseko

Uthuli kunye nongcoliseko:uthuli, umsi, ioyile, njl. emoyeni zingena kwi-laser, nto leyo eya kungcolisa umphezulu we-optical kunye ne-circuit, nto leyo ebangela ukufunxwa kobushushu bendawo, i-short circuit okanye i-arc.

Ukungcangcazela kunye nokothuka:Isiseko sokufakelwa esingazinzanga okanye ukungcangcazela kwangaphandle kuya kubangela ukuba ukulungelelaniswa kwezinto ezibonakalayo kuphambuke kwimeko efanelekileyo, kunciphise ukusebenza kakuhle kwemveliso, kwaye kunokubangela ukuba ulwakhiwo loomatshini lukhululeke kwiimeko ezinzima.

Umswakama:Ukufuma okugqithisileyo kuya kubangela ukufuma kumphezulu welensi, nto leyo enokubangela ukuba ifilimu iqhume lula phantsi kokukhanya kwelaser. Kwangaxeshanye, ukufuma kunokonakalisa izinto ze-elektroniki.

3. Indlela yokusebenza engalunganga

Ukutshintsha rhoqo i-hard Switching:Ukuvula nokucima i-laser rhoqo kuya kuzisa impembelelo enkulu yombane kunye nobushushu kumthombo wepompo kunye nenkqubo yamandla, nto leyo eya kunciphisa ubomi bayo.

Ukusebenza kwexesha elide phantsi kweeparamitha zomda:Vumela i-laser iqhubeke isebenza ngaphezulu kwe-90% yamandla aphezulu okanye igqithise kakhulu, nto leyo eya kwenza ukuba izinto zayo eziphambili zibe kwimeko yoxinzelelo oluphezulu kwaye zikhawulezise ukuguga.

Imithwalo Engangqinelaniyo:Kwezinye iintlobo zeelaser, ukungalingani kokukhanya komthwalo kunokubangela ukuba amandla athile abuyele ngaphakathi emngxunyeni, nto leyo ebangela ukungazinzi okanye umonakalo.

Ukonakala kwamandla neenkqubo zolawulo

Ukusebenza kombane we-drive kuyehla:Uzinzo lwamandla ombane/umbane ophumayo luba mandundu, kwaye i-ripple iyanda, engakwaziyo ukubonelela nge-drive eqinileyo necocekileyo kumthombo wepompo, nto leyo echaphazela ukusebenza kwayo kunye nobomi bayo.

Ukwaluphala kwesekethe yokulawula:Iiparameters zee-capacitors, ii-resistor kunye nezinye izinto zihamba ngokuhamba kwexesha kunye nobushushu, nto leyo ebangela ukwehla kokuchaneka kwenkqubo yokulawula.

Isishwankathelo kunye namanyathelo okuthintela

Ukubola kwamandla kwe-laser yinkqubo engenakuthinjwa ngokupheleleyo kodwa inokulawulwa ngokufanelekileyo kwaye incitshiswe.

Ukuze kulibazise ukubola kwamandla kakhulu kwaye kugcinwe ukusebenza okuzinzileyo kwelaser, kucetyiswa ukuba:

1. Ukubonelela ngendawo yokusebenza egqwesileyo:gcina ucocekile, ubushushu obungaguqukiyo, ukufuma okuphantsi, akukho kungcangcazela.

2. Qinisekisa ulawulo olufanelekileyo lobushushu:gcina inkqubo yokupholisa rhoqo ukuqinisekisa umgangatho wamanzi kunye nokuhamba kwawo.

3. Landela inkqubo yokusebenza eqhelekileyo:kuphephe ukutshintsha rhoqo nokusebenza ixesha elide phantsi kweemeko ezinzima.

4. Yenza ulondolozo lokuthintela rhoqo:Jonga rhoqo izinto ezibonakalayo, ucoce indlela ebonakalayo, kwaye utshintshe izinto ezisetyenziswayo (ezifana negesi kunye nezinto zokucoca) ngokweemfuno zomenzi.

5. Sebenzisa umbane ozinzileyo:qinisekisa ukuba i-voltage yombane izinzile, kwaye sebenzisa i-voltage stabilizer xa kuyimfuneko.

Ngokuqonda ezi ndlela zokunciphisa umbane kunye nokuthatha amanyathelo okhuseleko afanelekileyo, ubomi be-laser bunokwandiswa kakhulu kwaye ukusebenza kwemveliso okugcinwe kumjikelo wobomi kuzinzile ngakumbi.
