Kale mu 1916, katswiri wachiyuda wotchuka Einstein anatulukira chinsinsi cha lasers. Laser (dzina lonse: Light Amplification by Stimulated Emission of Radiation), kutanthauza "kukulitsa ndi cheza chokondoweza cha kuwala", akuyamikiridwa ngati chinthu china chopangidwa ndi anthu kuyambira zaka za zana la 20, kutsatira mphamvu za nyukiliya, makompyuta, ndi ma semiconductors. Ndilo "mpeni wothamanga kwambiri", "wolamulira wolondola kwambiri", ndi "kuwala kowala kwambiri". Dzina lonse lachingerezi la laser limafotokoza kale njira yayikulu yopangira laser. Laser ali osiyanasiyana ntchito, monga laser chodetsa, laser kuwotcherera, laser kudula, CHIKWANGWANI chamawonedwe kulankhulana, laser kuyambira, LiDAR, ndi zina zotero. Lero tikambirana momwe ma laser amakwaniritsira ntchito yoyezera mtunda.
Mfundo ya laser kuyambira
Nthawi zambiri, pali njira ziwiri zoyezera mtunda pogwiritsa ntchito ma laser: njira ya pulse ndi njira ya gawo. Mfundo ya laser pulse kuyambira ndikuti laser yotulutsidwa ndi chipangizo cha laser emission imawonetsedwa ndi chinthu choyezedwa kenako ndikulandiridwa ndi wolandila. Mwa kujambula nthawi imodzi yaulendo wozungulira wa laser, theka lachinthu cha liwiro la kuwala ndi nthawi yozungulira ndi mtunda pakati pa chida choyambira ndi chinthu choyezedwa. Kulondola kwa kugunda kwa njira yoyezera mtunda nthawi zambiri kumakhala mozungulira +/- 10 centimita. Njira ya gawo siliyesa gawo la laser, koma imayesa gawo la chizindikiro chosinthidwa pa laser.
Njira yothetsera laser
Pambuyo kumvetsetsa mfundo ya laser kuyambira, tiyeni tione ntchito yeniyeni ya laser kuyambira. Nthawi zambiri, kulondola kwa laser kumafuna kugwiritsa ntchito prism yowoneka bwino, pomwe chojambulira chomwe chimagwiritsidwa ntchito poyezera nyumba chimatha kuyeza mwachindunji mawonekedwewo kuchokera pakhoma losalala. Izi zili choncho makamaka chifukwa mtunda uli pafupi kwambiri, ndipo mphamvu ya chizindikiro yomwe imasonyezedwa ndi kuwala ndi yamphamvu mokwanira. Komabe, ngati mtunda uli patali kwambiri, mbali yotulutsa laser iyenera kukhala yolunjika pagalasi lowonetsera, apo ayi chizindikiro chobwerera chidzakhala chofooka kwambiri kuti chisapeze mtunda wolondola. Komabe, mu uinjiniya wothandiza, makina opangira ma laser amatha kugwiritsa ntchito mapepala opyapyala apulasitiki ngati malo owunikira kuti athetse vuto la laser yowopsa. zolinga zosiyanasiyana zoyezera molondola kwambiri.
Monga bizinesi yapamwamba kwambiri yomwe imaphatikiza kafukufuku ndi chitukuko ndi kupanga, Lumisopot yadzipanga yokha 905nm 1200m semiconductor laser kuyambira ma modules, 1535nm 3-15km erbium galasi laser kuyambira ma modules, ndi ma modules opitilira mtunda wautali wa laser. Mosiyana ndi makampani ena opanga ma laser, zogulitsa zathu zimawonetsa mawonekedwe ang'onoang'ono, kulemera kochepa, kutsika mtengo kwambiri, komanso kuthekera kopereka zochuluka. Kuphatikiza apo, mitundu yathu yazogulitsa ndizosiyanasiyana ndipo imatha kukwaniritsa zosowa zonse za laser. Ngati muli ndi chidwi ndi katundu wathu, chonde omasuka kulankhula nafe.
