Ibikorwa byingenzi biranga ibipimo bya sisitemu ya laser

1. Uburebure bwumurongo (igice: nm kugeza μm)

UwitekaUburebure bwa laserbyerekana uburebure bwumurongo wa electromagnetique itwarwa na laser. Ugereranije nubundi bwoko bwurumuri, ikintu cyingenzi cyalaserni uko ari monochromatic, bivuze ko uburebure bwumuraba wera cyane kandi bufite inshuro imwe gusa isobanuwe neza.

Itandukaniro riri hagati yuburebure butandukanye bwa laser:

Uburebure bwumurongo wa lazeri itukura mubusanzwe buri hagati ya 630nm-680nm, kandi urumuri rwasohotse rutukura, kandi ni na lazeri ikunze kugaragara cyane (ikoreshwa cyane cyane murwego rwo kugaburira ubuvuzi, nibindi);

Uburebure bwumurabyo wa lazeri muri rusange ni nka 532nm, (ikoreshwa cyane cyane murwego rwa lazeri, nibindi);

Uburebure bwa lazeri y'ubururu buri hagati ya 400nm-500nm (ikoreshwa cyane cyane kubaga laser);

Uv laser iri hagati ya 350nm-400nm (ikoreshwa cyane muri biomedicine);

Lazeri ya Infrared niyo idasanzwe, ukurikije intera yumurambararo hamwe nu murima wabisabye, uburebure bwa lazeri ya laser muri rusange buri hagati ya 700nm-1mm. Itsinda rya infragre irashobora kugabanywamo ibice bitatu: hafi ya infragre (NIR), infragre yo hagati (MIR) na infragre kure (FIR). Uburebure bwumurambararo uri hafi ya 750nm-1400nm, bukoreshwa cyane mu itumanaho rya fibre optique, amashusho y’ibinyabuzima ndetse n’ibikoresho byo kureba nijoro.

2. Imbaraga nimbaraga (ubumwe: W cyangwa J)

Imbaraga za Laserikoreshwa mugusobanura ingufu za optique ziva kumurongo uhoraho (CW) cyangwa impuzandengo ya laser ya pulsed. Byongeye kandi, laseri ya pulsed irangwa no kuba ingufu zabo zimpanuka zingana nimbaraga zisanzwe kandi zikagereranywa nigipimo cyo gusubiramo impiswi, kandi lazeri ifite imbaraga nimbaraga nyinshi mubisanzwe itanga ubushyuhe bwinshi.

Imirasire myinshi ya laser ifite umwirondoro wa Gaussian, bityo irradiance na flux byombi biri hejuru kumurongo wa optique ya laser kandi bikagabanuka uko gutandukana kuva optique byiyongera. Izindi lazeri zifite imyirondoro-yuzuye hejuru yumurambararo, bitandukanye nibiti bya Gaussiya, bigira umwirondoro uhoraho mugice cyambukiranya urumuri rwa lazeri no kugabanuka kwimbaraga. Kubwibyo, lazeri-yo hejuru ntishobora kugira imishwarara yo hejuru. Imbaraga zo hejuru z'igiti cyo muri Gaussiya zikubye kabiri iy'umurongo uringaniye ufite imbaraga zingana.

3. Igihe impiswi yamara (unit: fs to ms)

Igihe cya laser pulse igihe (ni ukuvuga ubugari bwa pulse) nigihe gitwara kugirango laser igere kuri kimwe cya kabiri cyingufu ntarengwa (FWHM).

 

4. Igipimo cyo gusubiramo (igice: Hz kugeza MHz)

Igipimo cyo gusubiramo alaser. Igipimo cyo gusubiramo kiringaniye ningufu za pulse kandi zingana nimbaraga zisanzwe. Nubwo igipimo cyo gusubiramo gikunze guterwa na laser yunguka hagati, mubihe byinshi, igipimo cyo gusubiramo kirashobora guhinduka. Igipimo cyinshi cyo gusubiramo gisubiza mugihe gito cyo kuruhuka ubushyuhe bwumuriro hejuru yubuso bwanyuma bwa laser optique, nayo iganisha ku gushyushya ibintu byihuse.

5. Gutandukana (igice gisanzwe: mrad)

Nubwo imirasire ya laser isanzwe itekerezwa nko guhurira hamwe, buri gihe iba irimo urugero runaka rwo gutandukana, isobanura urugero urumuri rutandukanya intera yiyongera kuva mukibuno cyurumuri rwa lazeri kubera gutandukana. Muri porogaramu zifite intera ndende ikora, nka sisitemu ya liDAR, aho ibintu bishobora kuba metero amagana uvuye kuri sisitemu ya laser, gutandukana biba ikibazo cyingenzi cyane.

6. Ingano yikibanza (igice: μm)

Ingano yikibanza cyibikoresho bya laser bisobanura urumuri rwa diameter kumurongo wibanze wa sisitemu yibanze. Mubisabwa byinshi, nko gutunganya ibikoresho no kubaga ubuvuzi, intego ni ukugabanya ingano yikibanza. Ibi byongerera imbaraga imbaraga kandi bikemerera kurema ibintu byiza cyane. Lens ya asiferique ikoreshwa kenshi aho gukoresha lensifike gakondo kugirango igabanye abera kandi itange ubunini buto bwibanze.

7. Intera y'akazi (igice: μm kugeza m)

Intera ikora ya sisitemu ya laser isanzwe isobanurwa nkintera yumubiri kuva optique ya nyuma ya optique (mubisanzwe lens yibanda) kubintu cyangwa hejuru laser yibandaho. Porogaramu zimwe, nka laseri yubuvuzi, mubisanzwe ishaka kugabanya intera ikora, mugihe izindi, nka kure ya sensing, mubisanzwe igamije kwagura intera ikora.
