Hi everyone,
I am trying to find some information about optics for high power
laser.
Especially heating (not damage) on lens, mount, mirror, etc related
with beam distortion and drift.
If you know any reference, would you please share information?
Thanks.

Try Sam's las faq. Just google it.

There really isn't going to be much specifically on high power optics.

There are a variety of issues specific to the use of high peak power and
high continuous power density. Optics manufacturers can provide data
on damage thresholds, losses, and so forth.

But perhaps, start here by giving us more of an idea of what you are
trying to do.

Thanks for your feedback.
What i am trying to do is to understand optics and opto-mechanical
design for high power laser to get better beam stability over large
environmental temperature range.
Examples:
lens materials
mirror substrate, coating, etc
lens and mirror mounts and its glue. gluing tech. etc
base plate design
etc.

What kind of high power laser are you talking about?
The optics for a CO2 laser are far different from those of an excimer
laser...

I just remembered people saying that thermal lensing happens in the rods of
strong lasers, so you might want to look further than the optics alone.

Hi,

Thermal lensing in the rod is certainly a big issue. However, it is
often overlooked that thermal lensing in glass (e.g. lenses, windows)
can be a problem as well. Make sure that whatever material you use has
a very low absorption at the wavelength you are operating at.

The definitive sources of information used to be, and possibly still are,
the proceedings of the annual Laser Damage conferences (used to be NBS, then
ASTM, then SPIE), held at Boulder, Colorado.

There was some of that work done in the late seventies and early
eighties. Much was classified, but some did get published in JOSA and
Optical Engineering. There was more published in those sources on
detector damage.
