AI Thread Summary
Visible light absorption in glass varies, with soda lime glass typically allowing around 90% transmission. To completely stop a laser beam in the visible spectrum, a significant thickness of glass is required, but the exact amount depends on the specific wavelength of the laser and the glass type. The discussion highlights that without precise parameters, providing a definitive answer is challenging. The transmission spectrum of soda lime glass serves as a reference for understanding these dynamics. Overall, the absorption properties of glass significantly influence laser beam penetration.

How much or what percentage of visible light is absorbed by glass, and how much glass would it take to completely stop a laser beam in the visible spectrum?

Have you looked at the wikipedia page for soda lime glass? It shows a typical transmission spectrum for said glass.

A lot. Such a vague question can only have a vague answer.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
