Cabbirka astaamaha waxqabadka ee muhiimka ah ee nidaamka laser

1

-Ga / -daLaser hivleththwaxay ka dhigan tahay mawjadaha mawjadda elektaroonigga ah ee ay wado laser. Marka loo eego noocyada kale ee iftiinka, muuqaal muhiim ah oo ahlaserTaasi waa in ay tahay monochromatic, oo macnaheedu yahay in mawjaddeeda ay saafi tahay oo ay leedahay hal jeer oo si fiican loo qeexay.

Farqiga u dhexeeya mawjadaha kala duwan ee laser:

Miiraha laser casaanka ah guud ahaan inta u dhaxaysa 630NM-680m-680m-680m-680m-iftiinka ah waa casaan, sidoo kale waa laser-ka ugu caansan (badiyaa loo adeegsado nalka nalka cuntada, iwm);

Miiraanku malaha leysar cagaaran guud ahaan waa qiyaastii 532mm, (badiyaa loo adeegsaday garoonka laser oo u dhexeeya, iwm.);

Miinooyinka buluugga ah ee leysarku waa guud ahaan inta u dhexeysa 400NM-500NM (badiyaa loo isticmaalo qalliinka laser);

UV Laser inta u dhaxaysa 350NM-400NM (badiyaa loo isticmaalo biomedicine);

Laser infrated Laser waa kan ugu gaarka ah, iyadoo loo eegayo mawjadaha xarkaha iyo arjiga, mawjadaha laslarrated Laserated Lasoth Lartance-ka guud ahaan wuxuu guud ahaan ku yaalliin tirada 700NM-1mm-1mm-1mm-1mm. Kooxda infakshanka ah ayaa loo kala qaybin karaa seddex koox-hoosaad: u dhow indrared (NIR), aflagaado dhexe (Mir) iyo infrared aad u fog (fir). Wajiga foosha ee soo-baxa waxay tahay qiyaastii 750NM-1400NM, oo si weyn loogu isticmaalo isgaarsiinta fiber-ka indhaha, sawirka biomedical sawirka iyo qalabka aragga ee habeenkii.

2. Awoodda iyo Tamarta (Cutubka: W ama J)

Awooda laserWaxaa loo isticmaalaa in lagu qeexo wax soo saarka korantada indhaha ee mowjad isdaba joog ah (cw) laser ama celceliska awooda laser la jeexjeexay. Intaas waxaa sii dheer, less-ka la jeexjeexay waxaa lagu gartaa xaqiiqda ah in tamartooda garaaca wadnaha ay u dhigantaa celceliska awoodda iyo jahwareerka sicirka ku celcelinta ee garaaca wadnaha, iyo tamarta leh awood sare iyo tamar badan ayaa badanaa soo saara kuleyl badan.

Inta badan alwaaxyada laser-ka waxay leeyihiin astaan ​​guud oo gaussian ah, sidaa darteed miyir-qabka iyo flux waxay labaduba ugu sarreeyaan dhidibka indhaha ee laser iyo hoos udhaca maadaama ay ka leexiyaan maadaama ay ka leexdo muuqaalka indhaha ee indhaha. Lasers kale waxay leeyihiin astaamo-dusha sare-dusha sare, si ka duwan alwaaxyada Gaussian, waxay leeyihiin astaan ​​aan caadi ahayn oo imaatinka ah oo ka sareeya qaybta iskutallaabta ee nambarka laser-ka iyo hoos udhaca degdega ah ee xoojinta. Sidaa darteed, lass-toper-ka sare ma leh macdan xoog leh. Awoodda ugu sarreysa ee magaalada Gaussian-ka ayaa labanlaab ah oo labanlaab ah dabaq leh oo isku dheelitiran oo isku celcelis isku celcelis ah.

3. Qiyaasta garaaca wadnaha (Qeybta: FS to MS)

Muddada garaaca ee laser (ie pulse ballac) waa waqtiga ay qaadanayso in laser-ka uu gaaro kala badh awooda ugu badan ee awoodda indhaha (FWWM).

 

4. Heerka Dib-u-celinta (Qeybta: Hz ilaa MHZ)

Heerka ku celcelinta ee alaser la jeexjeexay(tusaale ahaan heerka ku celcelinta garaaca garaaca wadnaha) wuxuu sharraxayaa tirada dadka seles-ka ah ee dhaliyay ilbidhiqsi kasta, taasi waa, taasi waa isugeyntii firta waqtiga isku xigxiga wadnaha. Heerka ku celcelintu waa mid aad u dhiganta tamarta garaacista garaaca wadnaha iyo u dhiganta celceliska awooda. In kasta oo heerka ku celcelintu uu caadi ahaan ku tiirsan yahay laser inuu helo dhexdhexaad, xaalado badan, heerka ku celcelinta waa la beddeli karaa. Heerka ku celcelinta ee sare wuxuu ku dhacaa waqti nasasho kuleyl gaagaaban oo dusha sare ah iyo diiradda ugu dambeysa ee diiradda loo saaro sheyga indhaha ee less, kaas oo iyana horseedaysa kuleylka si dhakhso ah ee maaddada.

5. Qeybta kaladuwan (Qeybta caadiga ah: Mrad)

In kasta oo laambadaha laser guud ahaan loo maleeyo inay isku dhaftaan, waxay had iyo jeer ka kooban yihiin xaddi badan oo kala jaad ah, kaas oo sharxaya heerka ay ku kala firidhsan yihiin masaafada sii kordhaya ee ka soo baxa masaafada sii kordhaya ee ka mid ah masaafada lasher. Codsiyada masaafada dheer ee shaqada, sida nidaamyada Liilalka, halkaasoo walxaha laga yaabo inay ka fogaadaan boqolaal mitir oo ka socda nidaamka laser, kala-baxa wuxuu noqdaa dhibaato gaar ah.

6. Cabbirka dhibicda (Qeybta: μm)

Cabbirka Spot ee Laser Lasher Laser ee diirada lagu saarayo ayaa qeexaya dhexroorkii lo'da ee ah barta aaladda ee nidaamka lennida diiradda lagu saarayo. Codsiyo badan, sida wax ka qabashada qalabka iyo qalliinka caafimaadka, hadafku waa in la yareeyo cabirkii dhibic. Tani waxay kordhisaa cufnaanta korantada waxayna u oggolaaneysaa abuurista astaamaha si gaar ah loo shubay. Muraayadaha dharka lagu xiro waxaa badanaa loo isticmaalaa halkii muraayadaha indhaha ee dhaqanka si loo yareeyo is-afgaradka lafdhabarta oo ay soo saaraan cabir yar oo heersare ah.

7. Masaafada shaqada (Cutub: μm to m)

Fogaanta hawlgalka ee nidaamka laser-ka waxaa badanaa lagu qeexaa masaafada jireed ee ka timaada sheyga ugu dambeeya ee ugu dambeeya (badiyaa laxeynta lens) si shay ama dusha sare ee laserku diiradda saarayo. Codsiyada qaarkood, sida kuwa la-kireystaha caafimaadka, sida caadiga ah waxay raadiyaan yaraynta masaafada hawlgalka, halka kuwa kalena, sida dareenka fog, sida caadiga ah ujeedadoodu tahay in la kordhiyo masaafada masaafada fog.
