Amapharamitha abalulekile wokusebenza kohlelo lwe-Laser System

1. I-Wavelength (iyunithi: nm to μm)

Le khasiI-Laser Wavelengthimele amandla egagasi le-electromagnetic athwalwa yi-laser. Qhathanisa nezinye izinhlobo zokukhanya, isici esibalulekile sei-laserNgabe yiwona i-monochromatic, okusho ukuthi i-wavelength yayo ihlanzekile kakhulu futhi inemvamisa eyodwa echazwe kahle.

Umehluko phakathi kwama-wavelength ahlukene we-laser:

I-wavenwength ye-red laser ngokuvamile iphakathi kuka-630NM-680NM, futhi ukukhanya okukhishwe kubomvu, futhi futhi kuyi-laser ejwayelekile kakhulu (ikakhulukazi isetshenziswa emkhakheni wokukhanya kokudla kwezokwelapha, njll.);

I-wavenwength ye-Green Laser ngokuvamile ingama-532NM, (ikakhulukazi asetshenziswa emkhakheni we-laser ranging, njll.);

I-Blue Laser Wavelength imvamisa phakathi kwe-400nm-500nm (ikakhulukazi esetshenziselwa ukuhlinzwa kwe-laser);

I-UV laser phakathi kuka-350nm-400nm (ikakhulukazi esetshenziswa kakhulu eBiomedicine);

I-laser ene-infrared iyona ekhetheke kakhulu, ngokusho kwalobubanzi be-wavengeth kanye ne-application, i-laser wavength ngokuvamile itholakala ebangeni le-700nm-1mm. I-infrared band ingaphinde ihlukaniswe yaba ama-band amathathu: eduze kwe-infrared (NIR), iMiddle infrared (MIR) futhi i-Far infrared (fir). Ububanzi be-wavenweth obuseduze obuseduze bungama-750nm-1400nm, asetshenziswa kabanzi ekuxhumaneni kwe-fiber okubonakalayo, ukucabanga kwe-biomedical kanye nemishini yokubuka ebusuku ebusuku.

2. Amandla namandla (iyunithi: w noma j)

Amandla we-Laserisetshenziselwa ukuchaza umphumela wamandla we-optical wamandla we-wave (cw) laser noma amandla aphakathi we-laser ecindezelwe. Ngaphezu kwalokho, ama-lasers agcwele ama-pulse abonakala ngeqiniso lokuthi amandla abo okuphambukisa alingana namandla aphakathi kanye nokulingana ngokweqile kwezinga lokuphindaphindeka kwamandla okuphindaphindwa kwamandla, kanye nama-laser anamandla aphezulu kanye namandla anamandla okushisa okuphezulu.

Iningi le-laser beams linephrofayili ye-gaussian beam, ngakho-ke i-irradiance ne-flux zombili ziphezulu kakhulu kwi-axis ye-laser futhi yehla njengoba ukuphambuka kusuka ku-axis optical kukhuphuka. Amanye ama-lasers anamaphrofayili we-flat-apped breased ot, ngokungafani nama-gaussian beams, abe nephrofayili ye-iradian engxenyeni yengxenye yesiphambano yokwehla kwesiphambano sokwehla kwesiphambano. Ngakho-ke, ama-lasers aphezulu aphezulu awanayo i-iradiance ephezulu. Amandla we-Peak of Gaussian Ugongolo aphindwe kabili kwe-flat-aspen open ngamandla afanayo aphakathi.

3. Isikhathi sokudlala (iyunithi: FS kuya ku-MS)

Isikhathi se-laser Pulse (ie Fourth Fourth) isikhathi esithatha isikhathi se-laser ukuba sifinyelele uhhafu wamandla aphezulu aphezulu (i-FWHM).

 

I-4. Izinga lokuphindaphinda (iyunithi: Hz kuya eMhz)

Izinga lokuphindaphinda kweI-Laser egcwele. Izinga lokuphindaphinda lilingana kakhulu nangamandla we-pulse futhi alingana namandla aphakathi. Yize izinga lokuphindaphinda livame ukuncika ku-laser ukuthola inzuzo, ezimweni eziningi, isilinganiso sokuphindaphinda singashintshwa. Inani eliphakeme lokuphindaphinda liphumela esikhathini sokuphumula esifushane sokuphumula sendawo nokugxila kokugcina kwento ye-laser optical, okuholela ekufuneni okusheshayo kwezinto ezibonakalayo.

I-5. Divergence (Iyunithi ejwayelekile: UMRAD)

Yize imishayo ye-laser ngokuvamile icatshangwa njengokushayeka, ihlala inemali ethile yokuhlukahluka, echaza ubukhulu lapho ugongolo luphambuka ebangeni elikhulayo kusukela okhalweni lolwandle lwe-laser ngenxa yokungafani. Kuzinhlelo zokusebenza ezinamabanga amade okusebenza, njengezinhlelo ze-lidar, lapho izinto zingaba ngamakhulu amamitha kude ukusuka ohlelweni lwe-laser, ukuphambuka kuba yinkinga ebaluleke kakhulu.

I-6. Usayizi we-Spot (unit: μm)

Usayizi webala lofuya we-laser ogxile uchaza ububanzi be-beam endaweni efanelekile yokugxila kwe-lens system. Kuzinhlelo eziningi, njengokucubungula ngokwezinto ezibonakalayo kanye nokuhlinzwa kwezokwelapha, inhloso ukunciphisa usayizi wendawo. Lokhu kukhulisa ukuqina kwamandla futhi kuvumela ukudalwa kwezici ezihle kakhulu. Ama-lens asperical ajwayele ukusetshenziswa esikhundleni se-lens yendabuko yendabuko yokunciphisa ukuhlukunyezwa okuyindilinga futhi akhiqize usayizi omncane webala.

7. Ibanga Lokusebenza (Iyunithi: μm kuya m)

Ibanga elisebenzayo lohlelo lwe-laser livame ukuchazwa njengebanga lomzimba ukusuka endaweni yokugcina ye-optical (imvamisa i-lens egxile) entweni noma ebusweni ukuthi i-laser igxila kuyo. Izicelo ezithile, ezinjengama-lasers ezokwelapha, zivame ukufuna ukunciphisa ibanga elisebenzayo, kanti ezinye, njengokuzwa okukude, ngokuvamile zihlose ukukhulisa uhla lwazo lokusebenza.
