Zofunikira Zofunikira Zogwirizira za Dongosolo la Laser

1.

Alaserdengthimayimira kuwala kwa funde la electromagnetic yopangidwa ndi laser. Poyerekeza ndi mitundu ina ya kuwala, gawo lofunikira lalaserNdiye kuti ndi zonunkhira, zomwe zikutanthauza kuti mafunde ake ndi oyera kwambiri ndipo amakhala ndi pafupipafupi.

Kusiyana pakati pa mafunde osiyanasiyana a laser:

The fulllength ya laser ofiira nthawi zambiri pakati pa 630nm-680nm, ndipo kuwalako kudatulutsa ndi kofiyira, ndipo ndi njira yofala kwambiri (makamaka laseji yowunikira kuchiritsa, etc.);

Wosewerera wa laser wa greet nthawi zambiri pafupifupi 532nm, (makamaka mu gawo la laser kuyambira, etc.);

Blue Laser Serviength ili nthawi yayitali pakati pa 400nm-500nm (makamaka amagwiritsidwa ntchito kwa opaleshoni ya laser);

UV laser pakati pa 350nm-400nm (makamaka kugwiritsidwa ntchito ku biomedicine);

Wosefera laser ndi wapadera kwambiri, malinga ndi mtundu wa funde ndi gawo la mapulogalamu, aftrared laser sosength nthawi zambiri amakhala mu 700nm-1mm. Gulu lodziwika likhoza kugawidwa m'magulu atatu: pafupi ndi infrared (nir), pakati kwambiri (mir) komanso infrared (fir). Mitundu yapafupi kwambiri ili pafupi 750nm-1400nm, yomwe imagwiritsidwa ntchito kwambiri kulumikizana ndi masamba amitsempha ndi mafayilo am'mimba komanso afanane usiku.

2. Mphamvu ndi mphamvu (unit: w kapena j)

Mphamvu ya laserimagwiritsidwa ntchito pofotokoza zamphamvu zamphamvu zopitilira muyeso (cw) laser kapena mphamvu yapakatikati pa laser. Kuphatikiza apo, masamba am'madzi amadziwika chifukwa chakuti mphamvu zawo ndizofanana ndi mphamvu zambiri komanso kuchuluka kwa zomwe zimachitika chifukwa cha zomwe zimachitika, ndipo mphamvu nthawi zambiri zimatulutsa kutentha kwambiri.

Manda ambiri a laser ali ndi mtengo wa gausian, motero urradicent ndi flux ndi onse okwera kwambiri pa axis ya laser ndikuchepera ngati kupatuka kwa ardical artis kumawonjezeka. Ma angalawa ena okhala ndi zotayika zokulirapo zomwe, mosiyana ndi zithunzi za Gasissia, zimakhala ndi mbiri yakale kudutsa gawo la mtanda wa laser ndipo ndikugwa mwachangu kwambiri. Chifukwa chake, ma Lasers apamwamba kwambiri alibe matenda osokoneza bongo. Mphamvu ya nsonga ya mtengo wa Gausian ndi kawiri konse kamiyala yosanja ndi mphamvu yomweyo.

Nthawi ya laser ya laser (mwachitsanzo, kutalika kwapafupina) ndi nthawi yomwe imatengera laser kuti afikire theka la mphamvu yayikulu (FWHM).

 

4. Mtengo wobwereza (unit: Hz ku MHZ)

Kuchuluka kobwereza kwa aKHALANI LAT. Mlingo wobwereza umakhala wofanana ndi kuyika mphamvu komanso molingana ndi mphamvu wamba. Ngakhale kuti kuchuluka kobwerezabwereza kumadalira laser kuti sikupeza sing'anga, nthawi zambiri, kuchuluka kobwereza kungasinthe. Zotsatira zobwerezabwereza zobwerezabwereza nthawi yochepetsetsa ya matenthedwe opumira pamalowo ndi chomaliza cha LA GAWO LA Laser, yomwe kumapangitsa kuti muwombetse zinthu.

5. Kusiyanasiyana (Konse Konse: Mrad)

Ngakhale makhadi a laser amaganiza kuti kumenyedwa, nthawi zonse kumakhala kusiyanasiyana, komwe kumafotokoza kuchuluka komwe mtengo umasokera mtunda wowonjezereka kwa mtengo wa laser. Muzogwiritsidwa ntchito ndi mtunda wautali, monga madera ogwirira ntchito, pomwe zinthu zitha kukhala mamita mazana angapo kuchokera ku dongosolo la laser, kusiyanasiyana kumakhala vuto lofunika kwambiri.

6. Kukula kwa malo (gawo: μm)

Kukula kwake kwa Laser pamtanda kumafotokoza bwino kwambiri pamtunda womwe umayang'ana kwambiri a Lens. M'mapulogalamu ambiri, monga kusamalira zinthu zakuthupi komanso kuchitidwa opaleshoni yazachipatala, cholinga ndikuchepetsa kukula kwa malo. Izi zimakulitsa kuchuluka kwa mphamvu ndikulola kuti chilengedwe cha mawonekedwe abwino. Mitundu yosiyanasiyana nthawi zambiri imagwiritsidwa ntchito m'malo mwa mitundu yachikhalidwe kuti muchepetse kutalika kwa ma sherric ndikupanga kukula kocheperako.

7. Kutalikirana (gawo: μm to m)

Mtunda wogwiritsira ntchito laser nthawi zambiri amatanthauza mtunda wa thupi lomaliza (nthawi zambiri limakhala ndi mandala kapena malo omwe aser amayang'ana. Mapulogalamu ena, monga ma Laser a zamankhwala, nthawi zambiri amayesetsa kuchepetsa mtunda, pomwe ena, monga kumveketsa bwino, nthawi zambiri amafunitsitsa kukulitsa malo awo ogwirira ntchito.
