I have a compass laser and I need a safety spectacle.
I have a question about the radation: does the laser also send
1064 nm lightwaves? and how much.
And what kind of spectacle do you wear?
They cost a fortune ( 190 Euro ).
Thanks.

I am told by folks who should know that there is no frquency other than 532 (green) that exists outside of the laser cavity (1064 and 808).
The real problem that we all face is if you use laser line goggles (spectacles) they also block the the beams you are using in your setup, making it almost impossible to adjust mirrors etc...
One option is to place a temporary beam splitter as your first optic on the table, and split off most of the power before it reaches your work area.
This allows you to build your setup with very low power output and then when you are ready for adjusting ratios you must remove the beamsplitter.
Also... you can apply red gels to any glasses which will help and as a last effort you might consider wearing polarized glasses and using your waveplate, manipulate the beam so it is orthogonal to the glasses you are wearing.

If you are going to buy goggles, then make sure they cover 432, 1064 and 808. Mine are ND 19 at theses frequencies. This way if you ever have to open the cavity you can do it safely.
I got mine in a group buy from Russia off the alt.lasers news group. If you post there they will steer you in the right direction.

I think that glasses for argon laser protection would do fine too,
and they appear sometimes on ebay for moderate amounts.
However, as already pointed out above: glasses are useless for doing
holography, as you need to see the beam - with the glasses on, it
is like having switched the laser off..... I got a couple of glasses
some while ago, and never ever had put them on for this reason. You
can always tune the power down to a few mW for adjustments (easy
for argon and the coherent 315 can do this as well), and then when
you don't move any more mirrors around and you need to determine
the exposure, you can crank it up. Stray beams usually stay on the
beam plane and if you stay above, you won't be hit. And 100mW is
not so terrible anyway, a stray beam will have only a minute fraction
of that.
