Dulmarka awoodda sarelaser semiconductorhorumarka qaybta koowaad
Iyada oo hufnaanta iyo awoodda ay sii wadaan inay soo hagaagaan, diodes laserdiodes laser) waxay sii wadi doontaa beddelka teknoolajiyada soo jireenka ah, taas oo beddeleysa habka wax loo sameeyo oo awood u siinaya horumarinta waxyaabo cusub.Fahamka horumarka la taaban karo ee leysarka semiconductor-ka awoodda sare leh ayaa sidoo kale xaddidan.Beddelka elektarooniga ah ee leysarka iyada oo loo marayo semiconductors ayaa markii ugu horreysay la soo bandhigay 1962-kii, horumarro kala duwan oo dheeri ah ayaa raacay kuwaas oo horseeday horumarro waaweyn oo ku beddelashada elektarooniga ah laser-wax soo saar sare leh.Horumarradan ayaa taageeray codsiyada muhiimka ah ee kaydinta indhaha ilaa isku xidhka indhaha ilaa qaybo badan oo warshado ah.
Dib u eegis lagu sameeyo horumarkan iyo horumarkooda is biirsaday ayaa muujinaya suurtagalnimada in saameyn weyn oo sii fican ay ku yeelan karaan meelo badan oo dhaqaalaha ah.Xaqiiqdii, iyada oo la sii wanaajinayo leysarka semiconductor-ka awoodda sare leh, goobta codsigeeda ayaa dardar gelin doonta ballaarinta, waxayna saameyn weyn ku yeelan doontaa kobaca dhaqaalaha.

Diode-pumped lasers-state adag iyolasers fiber
Horumarka leysarka semiconductor-ka awoodda sare leh ayaa sidoo kale horseeday horumarinta tikniyoolajiyadda laser-ka hoose, halkaas oo laser-ka semiconductor caadi ahaan loo isticmaalo in lagu kiciyo (pump) kirismaska doped-ka ah (laser-ka-daboole-bamgareynta laser-gobolka adag) ama fiilooyinka doped (fiber lasers).
In kasta oo laysarka semiconductor ay bixiyaan tamar laser hufan, yar iyo qiimo jaban, waxay sidoo kale leeyihiin laba xaddidaad oo muhiim ah: ma kaydiyaan tamar iftiinkooduna wuu xaddidan yahay.Asal ahaan, codsiyo badan ayaa u baahan laba laser oo faa'iido leh;Mid waxaa loo isticmaalaa in koronto loogu beddelo qiiqa laysarka, midda kalena waxaa loo adeegsadaa kor u qaadista iftiinka qiiqa.
Diode-pumped lasers-state adag.
Dabayaaqadii 1980-aadkii, adeegsiga leysarka semiconductor-ka si loogu shubo laysarka-gobolka adag wuxuu bilaabay inuu helo xiiso ganacsi oo muhiim ah.Diode-pumped solid-state lasers (DPSSL) waxay si weyn u yaraynaysaa xajmiga iyo kakanaanta hababka maaraynta kulaylka (oo u badan qaboojiyeyaasha wareegyada) iyo helitaanka qaybo, kuwaas oo taariikh ahaan isticmaalay nalalka arc si ay u soo saaraan kiristaalo laysarka adag.
Mawjadda dhererka laser-ka ee semiconductor waxaa lagu doortay iyadoo lagu saleynayo isugeynta sifooyinka nuugista muuqaalka leh ee dhexdhexaadka ah ee leysarka gobolka adag, kaas oo si weyn u yareeyn kara culeyska kulaylka marka la barbardhigo qiiqa qiiqa ballaaran ee nalka arc.Iyadoo la tixgelinayo caannimada laser-ka neodymium-doped ee siidaaya dhererka hirarka 1064nm, 808nm semiconductor laser wuxuu noqday wax soo saarka ugu waxtarka badan wax soo saarka laser semiconductor in ka badan 20 sano.
Waxtarka bamgareynta diode ee la wanaajiyay ee jiilka labaad waxaa suurtageliyay kororka dhalaalka ee leysarka qaab-dhismeedka qaab-badan leh iyo awoodda lagu dejiyo qiiqa qiiqa cidhiidhiga ah iyadoo la adeegsanayo bulk Bragg gratings (VBGS) bartamihii 2000-meeyadii.Sifooyinka nuugista ee daciifka ah iyo kuwa cidhiidhiga ah ee agagaarka 880nm ayaa kiciyay xiisaha weyn ee dabaylaha bamka iftiinka sare ee xasilloon.Laysaradan waxqabadka sare waxay suurtogal ka dhigayaan in si toos ah neodymium loogu shubo heerka laser sare ee 4F3/2, yaraynta dhimista quantum-ka oo markaa hagaajinaysa soo saarista qaabka aasaasiga ah ee celceliska awoodda sare, taas oo haddii kale lagu xaddidi lahaa muraayadaha kuleylka.
Horraantii tobankii sano ee labaad ee qarnigan, waxaan aragnay koror xoog leh oo koror ah oo ku yimid habka hal-wareegga ah ee 1064nm lasers, iyo sidoo kale leysarada beddelka soo noqnoqda ee ka shaqeynaya hirarka muuqda iyo ultraviolet.Marka la eego muddada dheer ee tamarta sare ee Nd: YAG iyo Nd: YVO4, hawlgalladan DPSSL Q-bedelku waxay bixiyaan tamar garaaca wadnaha sare iyo awoodda ugu sarreysa, taas oo ka dhigaysa mid ku habboon farsamaynta walxaha aflagaada ah iyo codsiyada micromachining-ka saxda ah.
