The common fabrication technologies of binary optical elements were expatiated, including etching, thin-film deposition, direct writing, excimer laser projection and gray-scale masks.
This paper briefly introduces photothermal techniques and their applications in optical thinfilm coating measurements and ti: sapphire laser crystal characterisation.
