Pubse Tamarta Lasers

Tamarta garaaca wadnaha ee laser-ka waxaa loola jeedaa tamarta ay ku faafto suuxdhuhu halbeeg waqti. Caadi ahaan, lasers-ka ayaa soo kici kara mowjadaha joogtada ah (cw) ama mowjadaha jarjaran, oo kan dambena ay muhiimad gaar ah u leeyihiin dalabyo badan sida qalabka wax ka qabashada, dareenka fog, qalabka caafimaadka, iyo cilmi baarista sayniska. Fahmitaanka astaamaha tamarta laser garaacis ah ee laser ayaa muhiim u ah hagaajinta waxqabadka iyo hagaajinta hufnaanta dalabka.

1. Qeexid iyo Cabbiraadda tamarta garaaca wadnaha

Tamarta laser garaacis ee laser waa tamar ay soo saarto garaaca wadnaha kasta, oo badanaa lagu cabiro joules (j). Si ka duwan mowjadaha joogtada ah (cw) lasers, less-ka la jeexjeexay ayaa sii daaya tamarta waqti yar, oo baaxadda tamarta ayaa caadi ahaan laxiriirta muddada garaaca wadnaha (ballaca garaaca wadnaha) iyo awoodda sare.

Tamarta garaaca wadnaha waxaa lagu xisaabin karaa iyadoo la adeegsanayo qaaciddada soo socota: e = ppeak × τ. Xagee E Energy Energy Energy Part (joules), ppeak waa awooda ugu sarreysa ee garaaca wadnaha (watts), iyo τ waa muddada garaaca wadnaha (sekan). Tan macnaheedu waa tamarta garaaca ah waxay si toos ah ula xiriirtaa labadaba korantada ugu sarreeya iyo ballaca wadnaha.

2. Waxyaabaha saameeya tamarta garaaca wadnaha

Dhowr arrimood oo saameyn ku leh tamarta garaaca wadnaha ee laser, oo ay ku jiraan:

①Naqshadeynta laser iyo nooca:
Noocyo kala duwan oo lasers ah ayaa saameeya cabirka suufka garaaca wadnaha. Tusaale ahaan, lasers-ka adag ee gobolka ayaa caadi ahaan bixiya tamar garaaca wadnaha oo sarreeya, oo ku habboon codsiyada u baahan wax soo saarka korantada. Fiber lasers, dhinaca kale, waxay soo saari kartaa goos goos leh awood sare iyadoo la hagaajinayo mawjaddooda.

②Qiyaasta garaaca wadnaha (ballaca wadnaha):
Weedhaha garaaca garaaca wadnaha, korantada sare ee waqtiga ugu sarreeya, kaas oo u saamaxaya tamarta garaaca wadnaha ee sareeya. Ballacadaha garaaca wadnaha ee la jeexjeexay ayaa sida caadiga ah lagu hagaajin karaa nanoseconds iyo picoseconds, oo leh qaabab gaagaaban oo si balaadhan loogu isticmaalo codsiyada saxda ah awgeed.

③Awoodda Laser Awoodda iyo Tamarta Waxtarka:
Waxqabadka laser-ka ayaa si toos ah u go'aamiya wax soo saarka tamarta. Nidaamyada laser-ka qaarkood waxay kor u qaadi karaan hufnaan ku-beddelasho ah iyada oo la saadaalinayo naqshadeynta helitaanka dhexdhexaadka dhexdhexaadka ah ama godka laser, taas oo ay ku sii kordhineyso tamarta garaaca wadnaha.

④Laser Apripers:
Nidaamyo badan oo korantada sare ah, cod-weyneyaal ayaa loo isticmaalaa in lagu kordhiyo tamarta wax soo saarka. Iyada oo loo marayo cod-weyne-myobi-marti-marxasho, tamarta garaaca wadnaha si weyn ayaa loo xoojin karaa.

⑤Laser drive hadda jira:
Wadada hada jirta ee ka dhigga laser diode ama nidaamka laser waa cunsur muhiim u ah saameynta awoodeeda wax soo saarka iyo tamarta garaaca wadnaha. Adigoo laqabsanaya hadda, gobolka xiisaha leh ee laser waa wax laga beddeli karaa, sidaasna saameyn ku yeelata wax soo saarka tamarta garaaca wadnaha.

3. Codsiyada tamarta garaaca ee laser

Cabbirka tamarta laser garaacis ee laseelku wuxuu go'aaminayaa ku habboonadiisa ku habboonaanta meelaha kala duwan. Qaar ka mid ah codsiyada caadiga ah waxaa ka mid ah:

①Waxqabadka:
Laser alxanka, goynta, iyo xajinta, suufka garaaca wadnaha ayaa si sax ah loo xakameyn karaa si loo gaaro wax ku ool ah oo wax sax ah. Tamarta garaaca wadnaha ee sareeya waxay ku habboon tahay in lagu hawlgalo ka baaraandegida aaladda birta, halka tamar yar-yar loo isticmaalo daaweynta dusha sare.

②Codsiyada Caafimaadka:
Lasers la jeexjeexay waxaa si weyn loogu isticmaalaa garoonka caafimaadka, gaar ahaan qalliinka laser, daaweynta maqaarka, iyo daweynta indhaha. Tusaale ahaan, less-ka suumanka leh ee tamarta sare leh waxay diiradda saari karaan tamarta laser ee mawjadaha gaarka ah ee mawjadaha gaarka ah ee ku saabsan aagagga yaryar ee loo yaqaan unugyada burooyinka buka ama daweynta xaaladaha indhaha.

③Liidha iyo xasaasiga fog:
Telekolojiyadda Liilar waxay ku tiirsan tahay tamarta safka sare ee garaaca wadnaha ee loo yaqaan 'lesse pulse' Korjoogteynta deegaanka, wadista iskood u madaxbannaan, iyo kormeerka diyaaradaha aan la raacayn, cabirka tamarta garaaca wadnaha ayaa si toos ah u saameeya masaafada ogaada masaafada iyo xallinta nidaamka habka.

④Cilmi baarista sayniska:
Kuwa la jeexjeexay waxay sidoo kale door muhiim ah ka ciyaaraan tijaabooyinka, kimistariga, iyo bayoolaji. Anigoo si sax ah u xakameynaya tamarta garaaca wadnaha, saynisyahannadu waxay sameyn karaan muraayad aad u sareeya oo laser-ka sarreeya, dardargelinta walxaha, iyo baaritaanka qaboojinta laser.

4. Qaababka lagu kordhinayo tamarta garaaca wadnaha

Qaababka caadiga ah ee lagu kordhiyo tamarta laser garaaca waxaa ka mid ah:

①Hesho Kordhinta Dhex-dhexaadka ah:
Adigoo xulanaya helitaan ku habboon oo dhexdhexaad ah oo hagaajinaya qaabeynta daloolka laser, tamarta wax soo saarka ee laser waa la kordhin karaa.

②Cod-weyneynta marxaladda badan ee Laser:
Agaarida masraxa marti-marxaladda ayaa si tartiib tartiib ah u kordhin kara tamarta garaaca wadnaha ee laser si ay u buuxiyaan shuruudaha codsiyada kaladuwan.

③Kordhinta wadista baabuurta hadda ama wadnaha:
Laqabsashada wadista baabuurta laser ee hadda ama ballaca garaaca wadnaha ayaa ku dambayn karta tamar badan oo garaaca wadnaha ah.

④Tiknolojiyadda isku-darka garaaca wadnaha:
Isticmaalka farsamooyinka isku-dhafan ee garaaca, muddada garaaca wadnaha waa la soo gaabin karaa, kordhinta awoodeeda ugu sarreysa iyo sii deynta tamar badan waqti gaaban.

5. Gunaanad

Tamarta laser garaacis waa xudunta furaha ah ee si toos ah u saameeya waxqabadka iyo adeegsiga lasdhiska ee qaybaha kala duwan. Iyada oo horumar sii kordheysa oo ku saabsan tikniyoolajiyadda laser, lasers-ka la jeexjeexay waxay lahaan doonaan codsiyo ballaaran oo ku saabsan warshado badan. Laga soo bilaabo saxnaanshaha mashiinka mashiinka fog iyo daawooyinka caafimaadka, wax soo saarka tamarta sare ee lasers-ka la jeexjeexay waxay fulisaa fursado cusub. Fahmitaanka fikradaha aasaasiga ah ee tamarta garaacista garaaca wadnaha iyo arrimaheeda saamayn ku yeelashada ayaa gacan ka geysan kara sidii ay u samayn lahaayeen xulashooyin saynis oo badan marka la qaabeeyo oo la adeegsanayo nidaamyada laser.
