China 532nm Circular Top-Hat Beam Shaping DOE | Malo Osalala a Φ60µm Opangira ndi Fakitale ya Green Lasers

DOE Yozungulira ya Chipewa Chokhala ndi Mtengo Wozungulira wa 532nm | Malo Osalala a Φ60µm a Laser Yobiriwira Chithunzi Chowonetsedwa

DOE Yozungulira ya Chipewa Chokhala ndi Mzere Wopanga Chipewa Chapamwamba cha 532nm | Malo Osalala a Φ60µm a Ma Laser Obiriwira

Ma DOE opangidwa ndi mipiringidzo ndi ena mwa zinthu zowunikira zomwe zimagwiritsidwa ntchito kwambiri (DOE). Ntchito yawo ndikupanga mipiringidzo yathyathyathya pamwamba yokhala ndi kugawa mphamvu kofanana, m'mphepete motsetsereka, komanso mawonekedwe osankhidwa ndi ogwiritsa ntchito.

Pogwiritsa ntchito ma microstructures, gawo lotumizira kuwala lomwe limadutsa mu diffractive optical element (DOE) limasinthidwa, zomwe zimapangitsa kuti gawo la kuwala kochitika lisinthe. Izi zimapangitsa kuti kuwalako kugawanike m'magawo osiyanasiyana a diffraction. Pogwiritsa ntchito khalidweli, pokonza ma diffraction orders ndi mtunda wa zinthu, kusokoneza kumachitika pa ndege inayake (nthawi zambiri pa infinity kapena focal plane ya lens), zomwe zimapangitsa kuti kuwala kugawikane.

Chojambula cha Diffractive Optical Element (DOE) ichi chapamwamba kwambiri chapangidwa makamaka kuti chigwiritsidwe ntchito ndi laser yobiriwira ya 532nm. Chimasintha bwino kuwala kwa laser ya Gaussian kukhala malo ofanana, ozungulira a Φ60 µm okhala ndi ma profiles otsetsereka komanso malo otentha ochepa.

Chopangidwa ndi mawonekedwe a magawo 16, chopangira kuwala ichi chimakwaniritsa bwino kwambiri >90% diffraction efficiency komanso >90% energy uniformity (RMS). Izi zimatsimikizira zotsatira zabwino kwambiri pa ntchito zofunika kwambiri monga laser micromachining, thin-film processing, laser marking, ndi biomedical device manufacturing.

DOE ili ndi mainchesi akunja a Φ25.4 mm (1-inch) okhala ndi chivindikiro chowonekera cha Φ12 mm komanso makulidwe a 2mm, zomwe zimathandiza kuti pakhale kuphatikizana kosasokonekera m'malo ambiri ogwiritsira ntchito ma optomechanical, mawilo osefera, ndi makina a laser.
