Dulmar guud oo ku saabsan awoodda sarelaysarka semiconductor-kaqaybta koowaad ee horumarinta
Maadaama hufnaanta iyo awooddu ay sii fiicnaanayaan, diode-yada laysarka (laser diode)darawalka diode-ka laysarka) waxay sii wadi doontaa inay beddesho teknoolojiyada dhaqameed, taasoo beddeleysa habka wax loo sameeyo iyo suurtogalinta horumarinta waxyaabaha cusub. Fahmidda horumarka muhiimka ah ee laysarka semiconductor-ka awoodda sare leh sidoo kale waa xaddidan tahay. Beddelka elektaroonada una beddelaya laysarka iyada oo loo marayo semiconductor-yada waxaa markii ugu horreysay la muujiyay 1962, waxaana ku xigay horumarro kala duwan oo is-waafaqsan kuwaas oo horseeday horumarro waaweyn oo ku yimid beddelka elektaroonada una beddelaya laysarka wax soo saarka sare leh. Horumarradani waxay taageereen codsiyada muhiimka ah laga bilaabo kaydinta indhaha ilaa shabakadda indhaha ilaa goobo warshadeed oo ballaaran.
Dib u eegis lagu sameeyay horumarkan iyo horumarkooda guud waxay iftiiminaysaa suurtagalnimada saameyn weyn oo baahsan oo ku yeelan karta dhinacyo badan oo dhaqaalaha ah. Xaqiiqdii, iyadoo la horumarinayo si joogto ah oo loo sameeyo laysarka semiconductor-ka awoodda sare leh, goobta codsigeeda ayaa dardar gelin doonta ballaarinta, waxayna yeelan doontaa saameyn qoto dheer oo ku saabsan kobaca dhaqaalaha.

laser-ka xaalad adag oo diode-ka lagu shubo iyolaysarka fiber-ka
Horumarka laga sameeyay laysarka semiconductor-ka ee awoodda sare leh ayaa sidoo kale horseeday horumarinta tignoolajiyada laysarka ee hoos u socda, halkaas oo laysarka semiconductor-ka badanaa loo isticmaalo in lagu kiciyo (bamka) kiristaallada doped-ka leh (laysarka adag ee diode-pumped) ama fiilooyinka doped-ka leh (laysarka fiber-ka).
In kasta oo laysarka semiconductor-ka ay bixiyaan tamar laysar oo hufan, yar, iyo mid jaban, haddana waxay sidoo kale leeyihiin laba xaddidaad oo muhiim ah: ma kaydiyaan tamar dhalaalkooduna waa xaddidan yahay. Asal ahaan, codsiyo badan waxay u baahan yihiin laba laysar oo waxtar leh; Mid waxaa loo isticmaalaa in korontada loogu beddelo sii deynta laysarka, kan kalena waxaa loo isticmaalaa in lagu xoojiyo dhalaalka sii deyntaas.
Laysarka xaalad adag oo diode-ka lagu shubo.
Dhammaadkii 1980-meeyadii, isticmaalka laysarka semiconductor-ka si loo bamgareeyo laysarka adag ee adag ayaa bilaabay inuu helo xiiso ganacsi oo muhiim ah. laysarka adag ee diode-pumped (DPSSL) ayaa si weyn u yareeya cabbirka iyo kakanaanta nidaamyada maaraynta kulaylka (badanaa qaboojiyeyaasha wareegga) waxayna helaan modules, kuwaas oo taariikh ahaan u isticmaali jiray laambadaha arc si loo bamgareeyo kiristaalo laysarka adag ee adag.
Mowjadaha laysarka semiconductor-ka waxaa lagu doortaa iyadoo lagu saleynayo isku-darka astaamaha nuugista muuqaalka iyo dhexdhexaadka faa'iidada ee laysarka adag, kaas oo si weyn u yareyn kara culeyska kulaylka marka la barbar dhigo muuqaalka sii deynta ballaaran ee laambadda arc. Marka la eego caannimada laysarka neodymium-doped ee soo saaraya hirarka 1064nm, laysarka semiconductor-ka 808nm wuxuu noqday badeecada ugu wax soo saarka badan wax soo saarka laysarka semiconductor-ka in ka badan 20 sano.
Waxtarka bamgareynta diode ee jiilka labaad waxaa suurtogal ka dhigay dhalaalka sii kordhaya ee laysarka semiconductor-ka ee qaababka badan leh iyo awoodda lagu xasilinayo ballaca khadadka qiiqa cidhiidhiga ah iyadoo la adeegsanayo shabagyada Bragg ee badan (VBGS) bartamihii 2000-meeyadii. Astaamaha nuugista muuqaalka ee daciifka ah iyo kuwa cidhiidhiga ah ee qiyaastii 880nm ayaa kiciyay xiiso weyn oo ku saabsan diode-yada bamka ee dhalaalaya sare leh ee si muuqata u deggan. Laser-yadan waxqabadka sare leh waxay suurtogal ka dhigayaan in neodymium si toos ah loogu shubo heerka sare ee laysarka ee 4F3/2, taasoo yaraynaysa yaraanta quantum-ka sidaas darteedna hagaajinaysa soo saarista qaabka aasaasiga ah ee awoodda celceliska sare, taas oo haddii kale ay xaddidi lahayd muraayadaha kulaylka.
Horraantii tobankii sano ee labaad ee qarnigan, waxaan aragnay koror xoog leh oo ku yimid laysarka 1064nm ee qaabka hal-transverse, iyo sidoo kale laysarka beddelka soo noqnoqda ee ka shaqeeya hirarka muuqda iyo kuwa ultraviolet-ka. Marka la eego cimriga tamarta sare ee dheer ee Nd: YAG iyo Nd: YVO4, hawlgalladan DPSSL Q-switched waxay bixiyaan tamar garaac sare iyo awood sare, taasoo ka dhigaysa kuwo ku habboon habaynta walxaha ablative iyo codsiyada micromachining-ka ee saxsan.
