Re: coherent photons

So I am now accused of thinking about it? -- hahah funny!

There are QDs and then there are QDs. Most QDs radiate monochromatic (but non-coherent light); however there is a new class of QDs in town the last few years - QD lasers that emit coherent photons when illuminated by another laser source. These special QDs are noted by "cladding" used to intensify confinement plus use of QD arrays to take advantage of "interaction" among dots and promote coherent light emission.

I hope we agree that coherent light is quite different from ordinary light (non-coherent) light. I.e., so all light is not the same :-)

An interesting thing (pretty sure you will agree) is that Al, Gallium, Ni cladding and copper dopants are used specifically in some of these special QD lasers.

Sesimic isolation is something that must be demonstrated to be believed - like a lot of thing audio-related :-). Even 8 years after the so-called isolation revolution, many people dismiss seismic influence out of hand. I have been building seismic isolation devices for 8 yrs, including a 6 DOF sub-1 Hz platform.
