ʻElemene Optical Diffractive Shaping Flat-Top Beam 532nm Rectangular (DOE)
Hoʻololi nā ʻano microstructures o kahi mea optical diffractive i ka pae hoʻoili o ka wavefront e hiki mai ana, kahi e hoʻokau ai i ka modulation phase ma ka mālamalama incident. ʻO ka hopena, ua māhele ʻia ke kukuna i nā kauoha diffraction like ʻole. Ma ka hoʻoponopono ʻana i ke kaumaha o kēia mau kauoha a me ka mamao i ka mokulele nānā, hiki i kekahi ke hana i ka hoʻopilikia kūkulu ma kahi i koho ʻia—maʻamau ma ka palena ʻole a i ʻole ma ka mokulele focal o kahi lens—a laila e hana ana i ke ʻano irradiance e pono ai.
Ua kūkulu ʻia kēia DOE no nā ʻōnaehana laser ʻōmaʻomaʻo 532 nm, e hoʻololi ana i kahi mea hoʻokomo Gaussian maʻamau i kahi ʻaoʻao pālahalaha huinahā e ana ana i 380 µm × 150 µm, me nā hoʻololi lihi ʻoi a me ka hoʻolaha like ʻana o ka ikaika.
Hāʻawi kona ʻano pae 16-pae i ka pono diffraction holoʻokoʻa e ʻoi aku ana ma mua o 90% a me ka like ʻana o ka ikehu ʻoi aku ka maikaʻi ma mua o 90% RMS, e kāohi pono ana i nā wahi wela a hoʻemi i ka pōʻino wela i nā noi hana kikoʻī.
Aia ka hāmeʻa i loko o kahi pūʻolo anawaena o waho Φ25.4 mm (1 ʻīniha) me kahi puka moakaka Φ15 mm, e kōkua ana i ka hoʻohui pololei ʻana i ka hapa nui o nā kau optical a me nā ʻākoakoa huila kānana.
NĀ MĀHELE HUAHANA
Ua kālele ʻia ka nalu i ka hāʻawi ʻana i nā huahana optical kiʻekiʻe no 20 mau makahiki
