Light - Black-bodies & Spontaneous / Stimulated Emission.

AI Thread Summary
Black-body radiation is primarily the result of spontaneous emission, with stimulated emission playing a minor role. In the context of the Sun, black-body radiation arises from the high temperatures and pressures that facilitate spontaneous photon emission. Everyday objects emit infrared radiation due to their temperature, which is also attributed to spontaneous emission. The distinction between black-body radiation and spontaneous emission lies in the nature of the processes involved, with black-body radiation being a statistical distribution of emitted photons across a spectrum. For a deeper understanding, further resources are recommended to clarify these concepts.

Hello,

I have a short question:

In relation to the Sun - is Black-body radiation ultimately the result of a combination of spontaneous (majority) and stimulated (minority) emission of photons?
In relation to the IR emissions from everyday objects due to their temperature - is Black-body radiation from the result of spontaneous emission?

If not, could somebody point me to a good description of why Blackbody radiation and Spontaneous emission are ultimately different? The internet is confused on the issue.

Thank you for any answers.

Dan

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...
