Abstract

Alkylene-bridged hybrid glass doped with Cr/CrOx was developed by sol-gel polymerization. When laser beam goes through a solid media, density wave is linear since heat doesn't decay through the media effectively in solid media. Interestingly, we observed a strong ‘acoustic response' from alkylene-bridged hybrid glass doped with Cr/CrOx due to high grating effect, high photo acoustic diffraction efficiency. The acoustic response generated from the doped hybrid glass was as compressive as liquid thus the acoustic refractive intensity generated from the hybrid glass was as strong as liquid. In our laser experiment, the diffraction efficiency (45%) of the glass is higher than that of methanol (25%). The hybrid glass can be used to develop diffraction beam modulators.
