not cutting through completely

[Jerry]

Hi Dave
sorry being a bit thick
by coupler do you mean the end of the laser tube nearest the first mirror?
Thanks
Jerry

Yup thats the one Jerry

Hi Dave
have cleaned the coupler , still no difference

Have a look at the other end of the tube Jerry , looking in through the glass are there any lines or cracks on the back face of the mirror? (you can only see the back of the mirror)

At the beam exit end have a look and see if you can see any cracks in the lens?

best wishes

Dave

Hi Dave
sorry its taken so long to get back to you, (student lessons getting in the way)
have had a look at both ends and can't see any cracks
both ends look fine
Thanks for your help

Morning Jerry,
So alignments good, mirrors / lens nice and clean and did you top up your water?
