Mukushandiswa kwelaser yemazuva ano, kunaka kwemwaranzi kwave chimwe chezvinhu zvakakosha pakuongorora mashandiro ese elaser.'Kucheka kwakanyatsojeka kwe micron-level mukugadzira kana kuona kure mu laser ranging, mhando yemwaranzi inowanzo sarudza kubudirira kana kukundikana kwekushandisa.
Saka, chii chaizvo chinonzi kunaka kwemuti? Zvinokanganisa sei mashandiro elaser? Uye munhu angasarudza sei kunaka kwemuti kwakakodzera kuti ukwane nezvinodiwa zvekushandisa?
1. Chii chinonzi Beam Quality?
Zvichitaurwa zviri nyore, kunaka kwedanda kunoreva hunhu hwekuparadzira kwedanda relaser munzvimbo. Rinotsanangura kuti danda rinogona kutarisisa sei, maitiro aro ekusiyana, uye kuti simba raro rinoparadzirwa zvakaenzana sei.
Muchiitiko chakanaka, danda relaser rakafanana nedanda reGaussian rakakwana, rine kona diki yekusiyana uye kushanda kwakanakisa kwekutarisa. Zvisinei, nekuda kwezvinhu zvakaita semaumbirwo enzvimbo, hunhu hwezvinhu, uye mhedzisiro yekupisa, danda relaser rechokwadi rinowanzo tambura nekupararira, kukanganiswa, kana kupindirana kwemultimode.—nokudaro zvichideredza kunaka kwedanda.
2. Zviratidzo zveUnhu hweBread Common
①M² Chinhu (Chinhu Chinoparira Kupararira kweBeam)
Iyo M² kukosha ndiyo parameter huru inoshandiswa kuongorora mhando yedanda.
M² = 1 inoratidza danda reGaussian rakakwana.
M² > 1 zvinoreva kuti hunhu hwemwenje hunoderera, uye kugona kwekutarisa kunoderera.
Mukushandiswa kwemaindasitiri, M² kukosha kuri pasi pe1.5 kunowanzo dikanwa, nepo lasers yegiredhi resainzi ichivavarira M² kukosha kuri pedyo ne1 sezvinobvira.
②Kupatsanurwa kweMatanda
Kusiyana kwemuti kunotsanangura kuti muti welaser unokura zvakadii paunofamba uchienda kure.
Makona madiki ekusiyana zvinoreva matanda akasimba, nzvimbo diki dzekutarisa, uye kunyatsojeka kukuru padaro refu.
③Mbiri yeBeam uye Kugoverwa kweSimba
Danda remhando yepamusoro rinofanira kunge riine chimiro chedanda chakaenzana, chakafanana chine nzvimbo yakasimba. Izvi zvinoita kuti simba ribudiswe zvakajeka uye zvinodzorwa pakucheka, kuisa chiratidzo, uye zvimwe zvinoshandiswa.
3. Mashandiro Emhando Yebeam Anoita Sei Mashandisirwo Enyika Yechokwadi?
①Kugadzirisa Nemazvo (Kucheka/Kunamira/Kumaka):
Hunhu hwedanda hunosarudza saizi yenzvimbo yakanangana nehukuru hwesimba, zvichikanganisa kururama kwemuchina uye kushanda zvakanaka.
②MaLaser Ekurapa:
Hunhu hwemwenje hunokanganisa kuti simba rinoendeswa sei kunyama uye kuti kupararira kwekupisa kunodzorwa sei.
③Kushandiswa kweLaser / LIDAR:
Hunhu hwedanda hunokanganisa zvakananga nzvimbo yekuona uye kugadziriswa kwenzvimbo.
④Kutaurirana Kwemaziso:
Hunhu hwemwenje hunokanganisa kuchena kwechiratidzo uye kugona kwebandwidth.
⑤Tsvagiridzo yeSainzi:
Hunhu hwedanda hunovimbisa kubatana uye kugadzikana mukupindira kana kuedza kwemaziso kusiri kwemutsara.
4. Zvinhu Zvikuru Zvinokanganisa Hunhu hweBeam
①Dhizaini yeChimiro cheLaser:
Malaser emhando imwe chete anowanzo kupa beam quality iri nani kupfuura malaser emhando dzakasiyana.
②Dhizaini yeGain Medium & Resonator:
Izvi zvinopesvedzera kugoverwa kwemodhi uye kugadzikana kwemwaranzi.
③Kutarisira Mhedzisiro Yekupisa:
Kusapisa zvakanaka kunogona kukonzera kupisa kwemagirazi uye kukanganisa mwenje.
④Kufanana kwePombi & Magadzirirwo eWaveguide:
Kusashanda zvakanaka kwepombi kana zvikanganiso zvemuumbi zvinogona kukonzera kuora kwechimiro chedanda.
5. Maitiro Ekuvandudza Hunhu hweBeam
①Gadzirisa Kugadzirwa Kwemidziyo:
Shandisa mawaveguides emodhi imwe chete uye magadzirirwo esymmetric resonator.
②Kutarisira Kupisa:
Sanganisa ma "heat sinks" anoshanda zvakanaka kana kuti "active cooling" kuti uderedze kukanganiswa kwe "heat" kunokonzerwa nekupisa.
③Magirazi Anoumba Matanda:
Isa ma collimator, ma spatial filters, kana ma mode converters.
④Kudzora Kwedhijitari & Mhinduro:
Shandisa nzira yekuona mafungu emhepo panguva chaiyo uye nzira yekuona mafungu emagetsi kuti ugadzirise mafungu nenzira inochinja-chinja.
6. Mhedziso
Hunhu hwedanda hunopfuura kungova parameter chaiyo—it's the"kodhi chaiyo""yelaser'mashandiro.
Mukushandiswa kwenyika chaiyo, mhando yepamusoro yemwaranzi inogona kuwedzera zvakanyanya kushanda zvakanaka, kururama, uye kuvimbika kwemasisitimu elaser. Kune vashandisi vanoda kushanda kwepamusoro uye kugadzikana, mhando yemwaranzi inofanira kuva chinhu chikuru chekufunga nezvacho pakusarudza laser.
Sezvo tekinoroji yelaser ichiramba ichichinja, tinogona kutarisira kudzora kuri nani kwemwaranzi mumidziyo midiki uye kuwanda kwesimba rakawanda.—kugadzira nzira yemikana mitsva mukugadzira zvinhu zvepamusoro, mushonga wekugadzira zvinhu nemazvo, zvemuchadenga, nezvimwewo.
