[Laser] Is it sill alive? If so I have a question.

Sat May 12 20:01:11 EDT 2018

I just tossed my question out there, I had noticed a BIG drop off in
activity. Sure
seems that we should still be pushing at it. But you get all overloaded
with other
stuff and that laser project keeps on getting further and further down the
road.

What with the proliferation of diodes from one end of the spectrum to the
other
with the absence of only amber (yea, you can do it with a DPSS setup but it
is
not efficient and expensive) be interesting to see what can be done with the
newer wavelengths. Of course we know that green and up are going to see
more and more attenuation but still be interesting to see what can be done.

I ordered some 515nm diodes the other day from China, when I got them they
sure looked more like 495nm vice 515. That is the first job that goes on my
spectrogaph as soon as I get the thing to show me the numbers they way they
should be.

That said there is a lot of stuff out there that may make the FSO even more
fun to do.

By way many of the low power green diodes are also TEM00 mode for what
ever it is worth.
