1064nm Circular Top-Hat Beam Shaping DOE | Malo Osalala a Φ50µm a Infrared (IR) Lasers

Ma DOE opanga mipiringidzo amapanga mipiringidzo yathyathyathya pamwamba yomwe imadziwika ndi mphamvu yofanana, kusintha kwakukulu pamalire, ndi mawonekedwe omwe amafotokozedwa ndi wogwiritsa ntchito. Chifukwa cha kusinthasintha kumeneku, ali m'gulu la zinthu zowunikira zomwe zimagwiritsidwa ntchito kwambiri masiku ano.

Tsatanetsatane wa Zamalonda

Ma tag a Zamalonda

Kugawa kwa mphamvu ya kuwala kumapangidwa pamalo osankhidwa (omwe nthawi zambiri amakhala pamalo osatha kapena pamalo ozungulira a lens) kudzera mu zotsatira zosokoneza. Izi zimatheka pokonza ma diffraction orders ndi mtunda wa chinthucho. Njira yoyambira imayamba ndi malo opangidwa ndi DOE, omwe amasintha gawo lotumizira la kuwala kwa laser, potero amagwiritsa ntchito phase modulation ku incident wavefront ndikuigawa m'magawo angapo.

Yokhala ndi mainchesi akunja a Φ25.4 mm (inchi 1) ndi chitseko chowonekera cha Φ12 mm, DOE iyi yogwira ntchito kwambiri idapangidwa kuti igwirizane ndi zomangira za optomechanical zomwe zimagwiritsidwa ntchito popanda kusintha. Ikagwiritsidwa ntchito ndi ma laser obiriwira a 532 nm, imasinthanso kuwala kwa Gaussian kukhala bwalo lathyathyathya la Φ60 µm lokhala ndi m'mbali zakuthwa, kuwala kofanana, komanso kukwera pang'ono kwamphamvu.

Kapangidwe ka pamwamba ka magawo 16 kamapereka mphamvu yonse ya diffraction ya >90% ndi kufanana kwa >90% RMS, zomwe zimapangitsa kuti ikhale yoyenera kukonza bwino mafilimu opyapyala, micromachining, ndi kupanga zida zamankhwala.
