1, qaab-dhismeedka bamka iftiinka booska

Wax soo saarka bamka indhaha ee hore ee loo yaqaan 'optic lasers' ayaa inta badan la isticmaalaa,laysarWax soo saarku, awooddiisa wax soo saarku way yar tahay, si loo si dhakhso ah u hagaajiyo awoodda wax soo saarka ee laysarka fiber-ka muddo gaaban gudaheed waxaa jira dhibaato weyn. Sannadkii 1999, awoodda wax soo saarka ee cilmi-baarista iyo horumarinta laysarka fiber-ka ayaa markii ugu horreysay jabtay 10,000 watts, qaab-dhismeedka laysarka fiber-ka ayaa inta badan ahaa isticmaalka bamka laba-geesoodka ah ee indhaha, oo sameeya resonator, iyadoo baaritaanka hufnaanta laysarka fiber-ka uu gaaray 58.3%.
Si kastaba ha ahaatee, inkastoo isticmaalka nalka bamka fiber-ka iyo tiknoolajiyada isku xidhka laser-ka si loo horumariyo laser-ka fiber-ka ay si wax ku ool ah u hagaajin karaan awoodda wax soo saarka ee laser-ka fiber-ka, laakiin isla markaas waxaa jira isku-dhafan, taas oo aan ku habboonayn muraayadda indhaha inay dhisto waddada indhaha, marka laser-ka loo baahdo in la dhaqaajiyo inta lagu jiro dhismaha waddada indhaha, markaa waddada indhaha ayaa sidoo kale u baahan in dib loo hagaajiyo, taas oo xaddidaysa isticmaalka ballaaran ee laser-ka fiber-ka qaab-dhismeedka bamka indhaha.

2, qaab-dhismeedka oscillator-ka tooska ah iyo qaab-dhismeedka MOPA

Iyadoo la horumarinayo laysarka fiber-ka, qalabka wax lagu dahaadho ee dahaarka ayaa si tartiib tartiib ah u beddelay qaybaha muraayadda, iyagoo fududeynaya tallaabooyinka horumarinta laysarka fiber-ka iyo si dadban u wanaajinaya hufnaanta dayactirka laysarka fiber-ka. Isbeddelkan horumarineed wuxuu calaamad u yahay waxqabadka tartiib tartiib ah ee laysarka fiber-ka. Qaab-dhismeedka oscillator-ka tooska ah iyo qaab-dhismeedka MOPA waa labada qaab-dhismeed ee ugu badan ee laysarka fiber-ka suuqa. Qaab-dhismeedka oscillator-ka tooska ah ayaa ah in shabaggu uu doorto hirarka inta lagu jiro geeddi-socodka oscillation-ka, ka dibna uu soo saaro hirarka la doortay, halka MOPA uu isticmaalo hirarka uu shabaggu doortay inuu noqdo iftiinka abuurka, iftiinka abuurkana waxaa lagu kordhiyaa ficilka amplifier-ka heerka koowaad, sidaa darteed awoodda wax soo saarka ee laysarka fiber-ka ayaa sidoo kale la horumarin doonaa ilaa xad gaar ah. Muddo dheer, laysarka fiber-ka oo leh qaab-dhismeedka MPOA ayaa loo isticmaalay qaab-dhismeedka la doorbiday ee laysarka fiber-ka awoodda sare leh. Si kastaba ha ahaatee, daraasado xigay ayaa lagu ogaaday in wax soo saarka awoodda sare leh ee qaab-dhismeedkan uu si fudud u horseedi karo xasillooni la'aanta qaybinta booska ee gudaha laser-ka fiber-ka, iyo iftiinka laser-ka soo baxaya uu saameyn doono ilaa xad, taas oo sidoo kale saameyn toos ah ku leh saameynta wax soo saarka awoodda sare leh.

Iyadoo la horumarinayo tiknoolajiyada bamgareynta

Mowjadaha bamgareynta ee laser-ka fiber-ka ee hore ee ytterbium-doped badanaa waa 915nm ama 975nm, laakiin labadan mowjadood ee bamgareynta ayaa ah meelaha ugu sarreeya ee nuugista ee ions-ka ytterbium, sidaa darteed waxaa loogu yeeraa bamgareynta tooska ah, bamgareynta tooska ah si weyn looma isticmaalin sababtoo ah luminta quantum-ka. Tiknoolajiyadda bamgareynta gudaha waa kordhinta tignoolajiyada bamgareynta tooska ah, taas oo mowjadaha u dhexeeya mowjadaha bamgareynta iyo mowjadaha gudbinta ay isku mid yihiin, heerka luminta quantum-ka ee bamgareynta gudaha-band-kana uu ka yar yahay kan bamgareynta tooska ah.

Laser fiber awood sare lehcaqabadda horumarinta tiknoolajiyada

In kasta oo laysarka fiber-ka uu leeyahay qiimo sare oo codsi ah oo ku saabsan militariga, caafimaadka iyo warshadaha kale, Shiinaha ayaa kor u qaaday codsiga ballaaran ee laysarka fiber-ka iyada oo loo marayo ku dhawaad ​​30 sano oo cilmi-baaris iyo horumarin tignoolajiyadeed ah, laakiin haddii aad rabto inaad samayso laysarka fiber-ka ayaa soo saari kara awood sare, weli waxaa jira caqabado badan oo ku jira tignoolajiyada jirta. Tusaale ahaan, in awoodda wax soo saarka ee laysarka fiber-ka ay gaari karto hal-fiber hal-qaab 36.6KW ah; Saamaynta awoodda bamgareynta ee awoodda wax soo saarka laysarka fiber-ka; Saamaynta saameynta muraayadaha kuleylka ee awoodda wax soo saarka ee laysarka fiber-ka.

Intaa waxaa dheer, cilmi-baarista tiknoolajiyada wax soo saarka korontada sare ee laser-ka fiber-ka waa inay sidoo kale tixgelisaa xasilloonida habka transverse iyo saameynta mugdiga photon-ka. Baaritaanka, waxaa cad in qodobka saameynta ee xasillooni darrada habka transverse-ka uu yahay kuleylka fiber-ka, saameynta mugdiga photon-kana waxay inta badan tilmaamaysaa marka laser-ka fiber-ka uu si joogto ah u soo saaro boqolaal watts ama dhowr kilowatts oo awood ah, awoodda wax soo saarku waxay muujin doontaa isbeddel degdeg ah oo hoos u dhac ah, waxaana jira heer xaddidan oo ku saabsan wax soo saarka korontada sare ee joogtada ah ee laser-ka fiber-ka.

In kasta oo sababaha gaarka ah ee saamaynta mugdiga photon aan si cad loo qeexin hadda, dadka badankiisu waxay aaminsan yihiin in xarunta cilladaha oksijiinta iyo nuugista wareejinta dallacaadda ay horseedi karaan dhacdada saamaynta mugdiga photon. Labadan arrimood, siyaabaha soo socda ayaa la soo jeediyay si loo joojiyo saameynta mugdiga photon. Sida aluminium, fosfooraska, iwm., si looga fogaado nuugista wareejinta dallacaadda, ka dibna fiber-ka firfircoon ee la hagaajiyay ayaa la tijaabiyaa oo la adeegsadaa, heerka gaarka ah waa in la ilaaliyo wax soo saarka awoodda 3KW dhowr saacadood iyo in la ilaaliyo wax soo saarka xasilloon ee awoodda 1KW muddo 100 saacadood ah.
