Laser Diode Bar: Awoodda Muhiimka ah ee Ka Danbaysa Codsiyada Laysarka Awood-sare

Maaddaama tignoolajiyada laysarka ay sii socoto inay horumarto, noocyada ilaha laysarka ayaa noqda kuwo aad u kala duwan. iyaga ka mid ah, bar diode laser u taagan soo baxay awood sare, qaab-dhismeedka is haysta, iyo maaraynta kulaylka aad u fiican, taasoo ka dhigaysa qayb lagama maarmaan ah in beeraha sida processing warshadaha, bilicda caafimaadka, ilaha bamka, iyo cilmi-baarista sayniska.

1. Waa maxay Baarka Diode ee Laser-ka?

Baar diode leysarka, oo sidoo kale loo yaqaano array diode laser, waa qalab leyssar semiconductor awood sare leh oo la sameeyay iyadoo la isku xirayo unugyo laser badan oo soo saaraya hal substrate caadi ah. Caadi ahaan, unug kasta oo sii daaya waxa uu ballaadhkiisu yahay 100 micrometer, halka balladhka baarka uu u dhexayn karo dhawr milimitir ilaa sentimitir. Sababtoo ah unugyo badan oo layser ah ayaa loo habeeyey dhinacba dhinac, baararka diode laser waxay keeni karaan koronto joogto ah ama garaacid min tobanaan watts ilaa in ka badan kilowatt.

2. Astaamaha Muhiimka ah

① Cufnaanta Awoodda Sare

Baararka diode-ka laser-ku waxay isku daraan wax soo saar badan oo meel bannaan ah si ay u bixiyaan awood aad u sarreeya, taasoo ka dhigaysa inay ku habboon yihiin codsiyada u baahan xaddi badan oo tamar ah.

② Maamulka kulaylka heer sare ah

Qaab dhismeedka barku wuxuu la jaan qaadayaa teknoolojiyadda baakadaha kala duwan, sida AuSn (dahab-dahab), all-indium, iyo baakadaha isku-dhafka ah, kuwaas oo kor u qaadaya kala-baxa kulaylka, kordhiya cimriga aaladda, iyo hubinta hawlgal xasilloon oo muddada dheer ah.

③ Mawjadaha dhaadheer ee la beddeli karo

Iyada oo ku xidhan codsiga, baararka diode laser waxaa loo qaabayn karaa hirarka hirarka kala duwan, sida 808 nm, 915 nm, 940 nm, iyo 976 nm. Habaynta mawjada dhererka gaarka ah ayaa sidoo kale diyaar ah si loo daboolo baahiyaha gaarka ah ee agabyada iyo nidaamyada kala duwan.

④ Qaabaynta Laydhka Dabacsan

Inkasta oo tayada laydhka ee baararka diode-ka laysarka ay guud ahaan ka hooseeyaan kuwa laser-ka-hal-habka ah, qaybaha indhaha sida muraayadaha muraayadaha, isku-xidhka fiber-ka, iyo nidaamyada muraayadaha-yar-yar ayaa loo isticmaali karaa in la isku daro ama diiradda saaro laydhka, kor u qaadista isdhexgalka iyo dabacsanaanta codsiyada nidaamka.

3. Goobaha Codsiga

① Warshadaha Warshadaha

Loo isticmaalo alxanka caaga ah, daawaynta kulaylka birta, nadiifinta laysarka, iyo calaamadaynta, baararka diode laser waxay bixiyaan saamiga waxqabadka-qiimaynta aad u fiican ee nidaamyada u baahan ilo laser awood sare leh.

② Caafimaadka iyo Bilicda

Tusaale ahaan, 808 nm baararka diode laser ayaa si weyn loogu isticmaalaa aaladaha timaha ka saara laysarka. Waxay bixiyaan awood sare iyo qoto dheer oo dhex dhexaad ah, si wax ku ool ah u burburiya timaha timaha iyada oo aan waxyeello u geysan unugyada ku wareegsan.

③ Ilaha Bamka ee Laserrada Fiberka

Nidaamyada laser fiber-ka ee awoodda sare leh, baararka diode-ka laysarka ayaa inta badan loo adeegsadaa ilaha bamka si ay u kiciyaan fiilooyinka Yb-doped ama Er-doped, iyagoo kaalin lama huraan ah ka ciyaaraya dhisidda nidaamyada laser awoodda sare leh.

④ Cilmi-baarista Sayniska iyo Difaaca

Baararka diode-ka laser-ka ayaa sidoo kale si weyn loogu isticmaalaa tignoolajiyada horumarsan sida tijaabooyinka fiisigiska tamarta sare leh, LiDAR, iyo isgaarsiinta laysarka, sababtuna tahay wax soo saarkooda deggan iyo sifooyinkooda la beddeli karo.

Maaddaama shuruudaha waxqabadka ee nidaamyada laysarka ay sii wadaan inay kor u kacaan, baararka diode laser waxay u kobcayaan xagga awood sare, isku halleyn weyn, arrimo qaab yar, iyo kharashyo hoose. Sida qayb muhiim ah oo ka mid ah nidaamyada codsiga laser, baararka diode laser si ballaaran ayaa looga qaataa dhammaan dhinacyada farsamada sare. Horumarka tignoolajiyada ee socda iyo silsilad warshadeed oo sii kordheysa, baararka diode laser ayaa la filayaa inay ku raaxaystaan ​​rajada suuqa oo balaadhan oo ay qaataan door istiraatiiji ah mustaqbalka.
