Reflective Holographic Gratings Chaw tsim tshuaj paus

Cov yam ntxwv tseem ceeb thiab qhov zoo ntawm holographic gratings muaj xws li spectrum dawb ntawm dab kab, siab wavefront zoo, tunable zawj profiles, thiab tsis tshua muaj siab groove densities. The fabrication process involves several critical steps—such as substrate preparation, photoresist coating, exposure, development, ion-beam etching, and thin-film coating—where even minor errors can compromise grating quality or lead to total failure. Cov txheej txheem pib los ntawm txheej txheej npaj substrate nrog ib txheej ntawm photoresist ntawm ib tug tuab tuab, ua raws li los ntawm raug nyob rau hauv ib tug cuam tshuam system los sau cov cuam tshuam fringes. Tom qab tsim cov substrate raug tsim los ua ib qho photoresist grating, ion-beam etching yog ua; Thaum kawg, kev ntxuav thiab nqus cov txheej txheem ua tiav qhov kev xav tau holographic grating tiav.
