M'magwiritsidwe amakono a laser, mtundu wa mtengo wakhala imodzi mwama metric ofunikira kwambiri pakuwunika magwiridwe antchito onse a laser. Kaya izo'Kudula kolondola kwa ma micron-level popanga kapena kuzindikira mtunda wautali pama laser, mtundu wa mtengo nthawi zambiri umatsimikizira kupambana kapena kulephera kwa ntchitoyo.
Ndiye, khalidwe la mtengo ndi chiyani kwenikweni? Kodi zimakhudza bwanji magwiridwe antchito a laser? Ndipo munthu angasankhire bwanji mtengo woyenerera kuti ugwirizane ndi zosowa zapadera?
1. Kodi Beam Quality ndi chiyani?
Mwachidule, mtengo wamtengo umatanthawuza kufalikira kwa malo a mtengo wa laser. Imalongosola momwe mtengo ungayang'anire bwino, machitidwe ake osiyana, ndi momwe mphamvu zake zimagawidwira mofanana.
M'malo abwino, mtengo wa laser umafanana ndi mtengo wabwino wa Gaussian, wokhala ndi mbali yaying'ono yosiyana komanso magwiridwe antchito abwino kwambiri. Komabe, chifukwa cha zinthu monga kapangidwe ka gwero, zinthu zakuthupi, ndi zotsatira za kutentha, matabwa enieni a laser nthawi zambiri amavutika ndi kufalikira, kupotoza, kapena kusokonezedwa kwa ma multimode.-potero kuchepetsa mtengo wamtengo.
2. Common Beam Quality Indicators
①M² Factor (Beam Propagation Factor)
The M² mtengo ndiye gawo loyamba lomwe limagwiritsidwa ntchito kuwunika mtundu wa mtengo.
M² = 1 ikuwonetsa mtengo wabwino wa Gaussian.
M² > 1 amatanthawuza kuti mtengo wamtengo umatsika, ndipo kuthekera koyang'ana kumakulirakulira.
Mu ntchito zamakampani, M² Makhalidwe ochepera 1.5 amafunikira nthawi zambiri, pomwe ma laser asayansi amangofuna M² ma values pafupi ndi 1 momwe ndingathere.
②Kusiyana kwa Beam
Kusiyanitsa kwa Beam kumatanthawuza kuchuluka kwa mtengo wa laser womwe umakulirakulira pamene ukufalikira mtunda wautali.
Makona ang'onoang'ono ang'onoang'ono amatanthawuza mizati yokhazikika kwambiri, timipata tating'onoting'ono, ndi kulondola kwambiri pa mtunda wautali.
③Mbiri ya Beam ndi Kugawa Mphamvu
Mtengo wapamwamba uyenera kukhala ndi mawonekedwe ofananirako, ofananirako amtengo wokhala ndi malo okwera kwambiri. Izi zimatsimikizira mphamvu zomveka bwino komanso zosinthika podula, kulemba chizindikiro, ndi ntchito zina.
3. Momwe Beam Quality Imakhudzira Ma Applications a Real-World
①Kukonzekera Kulondola (Kudula / Kuwotcherera / Kuyika Chizindikiro):
Kukula kwa mtengo kumatsimikizira kukula kwa malo ndi kachulukidwe ka mphamvu, zomwe zimakhudza kulondola kwa makina ndi mphamvu zake.
②Ma laser Medical:
Ubwino wa mtengo umakhudza momwe mphamvu imaperekera molondola ku minofu komanso momwe kufalikira kwamafuta kumayendetsedwa bwino.
③Kusintha kwa Laser / LIDAR:
Ubwino wa beam umakhudza mwachindunji kuchuluka kwazomwe zimadziwika komanso kusintha kwa malo.
④Kulumikizana kwa Optical:
Ubwino wa beam umakhudza chiyero cha mawonekedwe azizindikiro komanso kuchuluka kwa bandwidth.
⑤Kafukufuku wa Sayansi:
Ubwino wa beam umatsimikizira kugwirizana ndi kukhazikika pakusokoneza kapena kuyesa kosawoneka bwino.
4. Zinthu Zofunika Kwambiri Zokhudza Beam Quality
①Laser Structure Design:
Ma laser a single-mode nthawi zambiri amapereka mtengo wabwinoko kuposa ma laser amitundu yambiri.
②Pezani Mapangidwe Apakati & Resonator:
Izi zimakhudza kagawidwe kake komanso kukhazikika kwa mtengo.
③Thermal Effect Management:
Kutentha kosakwanira kungayambitse kutentha kwa lensing ndi kupotoza kwa mtengo.
④Pampu Uniformity & Waveguide Kapangidwe:
Kupopa kosagwirizana kapena kuwonongeka kwa kapangidwe kake kungayambitse kuwonongeka kwa mawonekedwe a mtengo.
5. Momwe Mungakulitsire Beam Quality
①Konzani Kapangidwe ka Chipangizo:
Gwiritsani ntchito ma waveguide amtundu umodzi ndi mapangidwe a symmetric resonator.
②Kasamalidwe ka Kutentha:
Gwirizanitsani masinki otenthetsera kapena kuziziritsa kogwira mtima kuti muchepetse kupotoza kopangidwa ndi matenthedwe.
③Beam Shaping Optics:
Ikani ma collimators, zosefera zapamalo, kapena zosinthira ma mode.
④Digital Control & Feedback:
Gwiritsirani ntchito kuzindikira kwa mafunde anthawi yeniyeni ndi ma optics osinthika kuti mukwaniritse kuwongolera kwamphamvu.
6. Mapeto
Ubwino wa mtengo siwongoyang'ana mawonekedwe-it's ndi“molondola kodi”wa laser's magwiridwe.
M'mapulogalamu adziko lapansi, mtengo wapamwamba wamtengo wapatali ukhoza kupititsa patsogolo mphamvu, kulondola, ndi kudalirika kwa makina a laser. Kwa ogwiritsa ntchito omwe akufuna kuchita bwino komanso kusasinthika, mtundu wa mtengo uyenera kuganiziridwa posankha laser.
Pamene ukadaulo wa laser ukupitilizabe kusinthika, titha kuyembekezera kuwongolera bwino kwamitengo muzida zing'onozing'ono komanso kachulukidwe kamphamvu kwambiri-kukonza njira zatsopano zopangira zotsogola, zamankhwala olondola, zakuthambo, ndi kupitilira apo.
