BWT waxay soo jeedisay aragtida cufan ee habaynta boosaska (DSBC) waxayna xaqiijisay saxnaanta DSBC iyada oo loo marayo tijaabada isha heerka kilowatt.Waqtigan xaadirka ah, awoodda hal tuubo ayaa la kordhiyey ilaa 15W-30W @ BPP≈5-12mm * mrad iyo waxtarka elektiroonigga ah> 60%, taas oo u sahlaysa ilaha tamarta sare leh oo ay weheliso wax soo saarka fiber si loo ilaaliyo sare. wax soo saarka dhalaalka iyadoo la dhimayo mugga, Waxaa suurtagal ah in la yareeyo miisaanka iyo hagaajinta waxtarka beddelka electro-optical.
Isticmaalka chip-ka hadda jira, BWT waxay siday u kala horreeyaan u xaqiiqsatay isha bamka leh dhexroorka udub-dhexaadka ah ee 135μm NA0.22 fiber-conupled saarka 420W wavelength-locked at 976nm, tayada ≈ 500g;iyo dhexroorka xudunta u ah 220μm NA0.22 fiber-ku-xidhan wax-soo-saarka 1000W hal mawjadaha dhererka 976nm (ama 915nm), tayada ≈ 400g isha bamka.
Mustaqbalka, iyada oo la wanaajinayo dhalaalka chip semiconductor iyo hufnaanta korantada, miisaanka fudud iyo ilaha awoodda sare ee tamarta ayaa door aan la bedeli karin ka ciyaari doona soo saarista ilaha iftiinka fibre-ka-yar ee awoodda sare, waxayna si firfircoon kor ugu qaadi doontaa horumarka. codsiyada warshadaha.
Hordhac
Laysarka Fiber-ka ayaa si degdeg ah u koray iyadoo ay ugu wacan tahay tayada alwaaxdooda aadka u wanaagsan iyo awoodaha ballaarinta awoodda dabacsan (isku darka fiber).Sanadihii la soo dhaafay, hal-hab laser fiber fiber-ka ah ayaa xaddiday TMI (xasillooni la'aanta qaabka transverse) iyo saamaynta SRS, iyo awoodda semiconductor toos ah bamgareynta fiber laser oscillators waxay ku kooban tahay 5kW
[1]Cod-weyneeye laysarka waxa kale oo lagu joojinayaa 10kW
[2].Inkasta oo awoodda wax-soo-saarka la kordhin karo iyada oo si habboon loo kordhiyo dhexroorka asaasiga ah, tayada wax-soo-saarka ayaa sidoo kale hoos u dhacda -1.Si kastaba ha ahaatee, baahida loo qabo hagaajinta dhalaalka ilaha matoorka semiconductor weli waa degdeg.
Shuruudaha tayada alwaaxyada ee codsiyada farsamaynta warshadaha maaha daruuri hal qaab.Si loo kordhiyo awoodda hal-fiber, dhowr habab-hooseeya ayaa la oggol yahay.Ilaa hadda, dhowr nooc oo hal-fiber ah iyo beam-isku-dhafan ilo iftiin badan oo laser ah oo ku salaysan 976nm bamgareynta in ka badan 5kW Iyadoo codsiyada dufcadda (inta badan goynta iyo alxanka alaabta birta ah), wax soo saarka ilaha tamarta sare ee u dhigma sidoo kale waa dufcad-cabbir.
Ka yar, fudud oo deggan
Xidhiidhka u dhexeeya chip semiconductor BPP iyo dhalaalka isha bamka
Saddex sano ka hor, dhalaalka 9xxnm chips wuxuu ahaa inta badan heerka 3W/mm*mrad@12W-100μm ballac xarigga & 2W/mm*mrad@18W-200μm ballac xadhig.Iyada oo ku saleysan jajabyada noocaas ah, BWT waxay ku guulaysataa 600W iyo 1000W 200μm NA0.22 fiber-coupled saarka-1.
Waqtigan xaadirka ah, dhalaalka 9xxnm chips wuxuu gaaray 3.75W / mm * mrad @ 15W-100μm strip width & 3W / mm * mrad @ 30W-230μm ballac, iyo waxtarka elektiroonigga ah ayaa asal ahaan lagu hayaa qiyaastii 60%.
Marka loo eego aragtida habaynta bannaan ee cufan [6], waxaa loo xisaabiyaa iyadoo loo eegayo celceliska waxtarka isku-xidhka fiber-ka ee 78% (soo-saarka laser-ka ee chip-ka ilaa wax-soo-saarka isku-xidhka fiber-ka: isku-darka iftiinka bannaan ee hal-mawjadda-hal-mawjadaha ah ee isku-dhafka ah iyo laydhka polarization ee isku-darka VBG la'aan). waxaana loo maleynayaa in chip-ku uu ku shaqeeyo awooda ugu sareysa (Chip BPP way ka duwan tahay qulqulo kala duwan), waxaan u diyaarinay khariidad xogta sida soo socota:
* Dhallaanka Chip VS Kala Duwan ee Dhexroorka Xudunta Fiber Isku-xidhka Awoodda
Waxaa laga heli karaa shaxanka kor ku xusan in marka fiber gaar ah (dhexroorka xudunta ah iyo NA ay go'an tahay) uu gaaro wax soo saar koronto oo gaar ah, chips leh dhalaal kala duwan, tirada jajabku waa ka duwan yahay, mugga iyo miisaanka isha bamka sidoo kale way kala duwan yihiin.Shuruudaha bamgareynta laser fiber-ka, haddii isha bamka laga sameeyay chips-yada kor ku xusan oo leh dhalaal kala duwan ayaa la doortaa, miisaanka iyo mugga laser fiber-ka ee awoodda isku midka ah ayaa gebi ahaanba ka duwan, iyo qaabeynta nidaamka qaboojinta biyaha sidoo kale waa aad uga duwan.
Waxtarka sare, cabbirka yar iyo miisaanka fudud ayaa ah isbeddellada lama huraanka ah ee horumarinta ilaha iftiinka laysarka mustaqbalka (haddii ay tahay laser diode, lasers-state lasers ama fiber lasers), iyo dhalaalka, hufnaanta iyo awoodda chips semiconductor ayaa door muhiim ah ka ciyaara. .
Fudud, dhalaal sare, isha bamka tamarta sare
Si aan ula qabsano isku-darka fiber-ka, waxaanu dooranay qeexitaannada fiber-ka caadiga ah: 135μm NA0.22 iyo 220μm NA0.22.Naqshadaynta indhaha ee labada ilo matoorka waxay qabataa habayn cufan oo meel bannaan ah iyo isku-darka alwaax ka samaysan polarization.
Waxaa ka mid ah, 420WLD waxay qabataa 3.75W/mm * mrad @ 15W chip iyo 135μm NA0.22 fiber, waxayna leedahay VBG qufulka hirarka dhererka, kaas oo buuxinaya shuruudaha 30-100% qufulka hirarka korantada, iyo hufnaanta korantada indhaha waa 41% .Jidhka LD wuxuu ka samaysan yahay walxo aluminium ah iyo qaab-dhismeedka sandwich [5].Chips-yada sare iyo kuwa hoose waxay wadaagaan kanaalka qaboojinta biyaha, taas oo wanaajisa isticmaalka booska.Habaynta barta iftiinka, spectrum iyo soo saarida awooda (awoodda fiber-ka) ayaa lagu muujiyay shaxanka:
*420W@135μm NA0.22 LD
Waxaan u dooranay 6 LDs heerkul sare iyo mid hooseeya iyo tijaabooyinka gariirka.Xogta imtixaanku waa sida soo socota:
* Tijaabada saamaynta heerkulka sare iyo hoose
* Tijaabada gariirka
1000WLD wuxuu qaataa 3W / mm * mrad @ 30W chip iyo 220μm NA0.22 fiber, kaas oo ku guuleysta 915nm iyo 976nm fiber-ku xiran wax soo saarka ee 1000W siday u kala horreeyaan, iyo waxtarka elektiroonigga ah waa> 44%.Jirka LD wuxuu kaloo ka samaysan yahay walxo aluminium ah.Si loo sii wado saamiga sare ee awoodda-bass, qolofka LD waa la fududeeyay iyadoo la raacayo shuruudaha hubinta xoogga qaabdhismeedka.Tayada LD, habaynta booska iyo awoodda wax soo saarka (awoodda fiber-ka) waa sida soo socota:
*1000W@220μm NA0.22 LD
Si loo hagaajiyo isku halaynta isha bamka, fiilada dhamaadka isku xidhka waxay qabataa fiyuuska dhamaadka quartz iyo farsamada shaandhaynta iftiinka, taas oo ka dhigaysa heerkulka fiber ka baxsan isha bamka meel u dhow heerkulka qolka.Lix 976nmLDs ayaa loo doortay shoog heerkul sare iyo mid hooseeya iyo tijaabooyin gariir.Natiijooyinka imtixaanku waa sida soo socota:
* Tijaabada saamaynta heerkulka sare iyo hoose
* Tijaabada saamaynta heerkulka sare iyo hoose
* Tijaabada gariirka
Gabagabo
Helitaanka wax soo saarka dhalaalka sare wuxuu ku yimaadaa kharashka waxtarka elektiroonigga ah, taas oo ah, awoodda wax-soo-saarka ugu sarreeya iyo waxtarka ugu sarreeya ee korantada isku mar lama heli karo, taas oo lagu go'aamiyo dhalaalka chip iyo inta jeer ee caadiga ah ee isku xirka. fiber.Tiknooloojiyada isku dhafka ah ee tignoolajiyada-tube-ka-kala-badan leh, dhalaalka iyo hufnaanta ayaa had iyo jeer ah yoolalka aan la gaari karin isku mar.Isku dheelitirnaanta waxtarka elektiroonigga ah iyo awoodda waa in lagu go'aamiyaa si waafaqsan codsiga gaarka ah.
