    Laser Radio Wave
AI Thread Summary
The discussion centers on the concept of building a radio-wave laser, specifically one that could be approximately 10km long. Participants clarify that "radio-wave" refers to frequency, and this technology is akin to a maser, which operates on microwave frequencies and has existed longer than lasers. There is curiosity about the feasibility of such a project and its potential applications, though no serious pursuit is indicated. The conversation highlights the need for further research into the capabilities and implications of radio-wave lasers. Overall, the topic raises intriguing questions about advanced laser technology and its future possibilities.

I am merely getting curious in thinking about building a radio-wave laser. I'm not seriously pursuing this, but I think it would be cool to build a laser that is ~10km in length. Is anyone aware of any research into this type of monstrosity? Any thoughts about the feasibility or the potential applications?

What do you mean by "radio-wave"?
Are you referring to the frequency?
If so, this is known as a maser (the m is for microwave) and they have been around for even longer than lasers.

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...
