A wave plate, iyo inonziwo phase retarder, chinhu chemagetsi chinoshandura polarization mamiriro emwenje nekuburitsa Optical nzira musiyano (kana chikamu musiyano) pakati pezviviri zvinoteedzera orthogonal polarization zvikamu. Kana chiitiko chechiedza chikapfuura nemafafitera akasangana nemhando dzakasiyana dzeparamendi, mwenje wekubuda wakasiyana, ungangoita mutsara wakaenzana, mwenje wakasarudzika, mwenje wedenderedzwa, zvichingodaro. yefurafura.

Mahwendefa eWave anowanzogadzirwa neebirefringent zvinhu zvine hunyanzvi saizi dzakadai quartz, calcite kana mica, ine demo rekutarisa rakafanana neafer kumusoro. Mahwendefa akajairwa akasara (kusanganisira λ / 2 uye λ / 4 wave mahwendefa) akavakirwa pamhepo-yakavakirwa dhizaini iyo inobvumira kushandiswa kwavo kwezvesimba-zvine simba zvine chikanganiso chakakomba kupfuura 10 J / cm² for 20 ns pulses pa 1064 nm.

Hafu (λ / 2) Wave Plate

Mushure mekupfuura nepasirosi ye2n / 2 wave, iwo mutsara wakaenzana pataroni, asi zvakadaro, pane musiyano wekona (2θ) pakati penduru inozunguzika yemagetsi akaunganidzwa pamwe nendege inoyerera yeiyo chiitiko chakaganhurirwa. Kana θ = 45 °, iyo vibration ndege yechiedza inobuda inoenderana neyekuzungunuka ndege yeichiitiko chechiitiko, ndiko kuti, kana θ = 45 °, iyo λ / 2 wave ndiro inogona kuchinja polarization state ne90 °.

Quarter (λ / 4) Wave Plate

Kana kona iripo pakati pechiitiko ichi inodzungudza ndege yechiedza chakapetwa uye nemeso axis yeafurati iri θ = 45 °, mwenje uchipfuura nepakati / 4 wave mundiro unotenderedzwa. Zvikasadaro, mushure mekupfuura nepasirosi kana 4 wave peturu, mwenje unotenderedzwa unowoneka mutsara. A λ / 4 wave ndiro ine yakaenzana mhedzisiro ine λ / 2 wave ndiro kana ichibvumira mwenje kuti ipfuure nepakati.
