About the Lab
Professor Young Won Lee's research lab specializes in advanced photonic materials and optical fabrication, with a focus on developing high-precision optical elements using laser-based techniques. The lab investigates the fundamental mechanisms of gelatin-based photoplates, particularly dichromated gelatin (DCG), to control stress and deformation during laser scanning processes. Their work centers on optimizing laser energy distribution and chemical composition to achieve desired optical shapes, such as spherical lenses, with minimal distortion. The lab also explores the role of energy saturation and inhomogeneous liquid flow in photopolymerization dynamics for improved optical element performance.

1In the fabrication process of optical elements (OEs) by the laser scanning method using a dichromated gelatin (DCG) photoplate, the expansion and drying stress of gelatine caused by inhomogeneous liquid flow inside the gelatine affects the shape of OEs. The reason this inhomogeneous liquid flow exists in the energy oversaturated parts of OEs is the presence of surplus energy. In order to obtain the OEs of desired spherical lens shape, the drying stress should be reduced and therefore the maximum
