That second one was very interesting to me as I am currently reading Walter Koechner's book on solid state laser engineering and specifically about materials used for Q-Switching like ADP, KDP, RDP, ADA, KDA, RDA and CDA. These are used as Pockels Cells or Kerr Cells with electric fields either parallel or perpendicular to the light axis. There is also a great deal of information here about the use of 1/4 wavelength and 1/2 wavelength wave plates to change the polarity of light in a single pass to 180 degrees making it possible to have the laser emit at 90 degrees to the axis of light travel. This is all done with birefringent crystals like calcite. All of it brings to mind the search for new crystals to do new things that haven't been accomplished so far.

Thanks for that, Encap. I've been a Kenny Loggins fan since the days of Loggins and Messina. I saw him at Fiddler's Green in Denver back in the early 90s with my daughter who was about 8 years old at the time.

Yes , Logins is great--Hall is killer also---
Daryl Hall and John Oats have more recorded Billboard hit releases than ANY Duo in the history of recorded music---interesting fact not many people know. See: https://en.wikipedia.org/wiki/Hall_%26_Oates

The Hall and Oats recorded songs are more amazing than people imagine. Hall and Oats are always thought of as an afterthought for whatever reasons---but they are actually awesome act and their recordings are examples of perfection in recording technique.

Thanks, Tero. I scanned the articles and the first, at least, is very similar to what I am reading now. I'll get back to them when I'm less busy. :thanks:

@Encap
I did know that about Hall and Oats. Daryl Hall is now a country western musician which is a genre I don't care for. I guess one never knows what is in the heart of these artists.
 
These look like fun. Be careful!

I am thinking about Oxygen/acetylene but that may be way too much ???

This is the most "Metal" band that I've ever seen! ;)

A very cool mechanical band that uses pneumatic cylinders to bring these guys to life! :yh:

 
Interesting to watch. Torture to listen to. You can't take human musicians out of the equation because that talent can't be replicated. Someone went to a lot of trouble trying, though.
 
Bowtie, that was pretty cool:)
Are the girl groupies robot's too?:thinking:

Paul, most of the music had to be recorded I would think..

First one reminded me of Jerry Lee Lewis from back in the 50s. You don't see a lot of people setting up a drum kit on the street. He was okay, but I know some much better. :thanks:
 
The more this goes on, it looks like Trump's campaign did in a big way. Everyday the news looks worse for him and his "hoax" theory he is trying so desperately to push.
 
You are either spouting known BS or you're lying to yourself, Trump was attacked by a corrupt system headed by Barry and the truth has come out, at this point the FBI 7th floor is in CYA mode.

It's time to drain the swamp as the swamp is exposed, the FBI is on the defensive, not the attack.

Granted the men and women of the FBI are mostly good people, but their leadership has been corrupted and the FBI let the Florida school shooter slip through some pretty huge cracks, it's time to drain this swamp.
