great thax


is there any reason why someone has disconnected it?
seems stupid to do that.

the previous owner didn´t know what it was used for

it connects directly to the anode block, under the screw where the other big red wire is...dig and you will fine the other end unless someone snipped it but yeah anode. what it does is it puts the water at the cathode end of the PT at anode potential so there is less corrosion that will stress and erode at the glass to metal seal at the anode block. It is not mission critical that it be hooked up laser will run fine without, you will get better PT life if you hook it up.

it´s alive

many thanx everybody


a new problem.
i get allot of "splatter"
or what it´s called?
on the wall around the beam
what should i do?

I thought we talked about this but. It is dirt on either the Output side of the output mirror or dirt on both sides of the beamsplitter in the OC holder.

it is probably the beam splitter from what I can see from the picture there...it is very bright spatter.

Could a beam that is aligned off-axis, and therefore possibly grazing the edge of the bore, als cause this kind of scattering?

In any case, cleaning optics never hurts. There is no such thing as a mirror that is tóó clean.

Be sure to follow Sam's Laser FAQ on optics cleaning though, as a 'quick wipe' could seriously damage the coating.

sure it could also be clipping the brewester stem...but the beamsplitter window looks very bright to me...not sure of power but it looks bright...just too much scatter.

the manual says that when turning off i should pull up the current and field to max.
but when i pass 34Amps it flips out with relays clicking and stuff??

is this normal over current protection?
why should i pull the current and field to max when turning off??

btw
it´s at 32Amps 1w in the pictures
it should go higher but it doesn´t want to
so maybe i should align the tube and clean the optics
do you guys think the fill is ok?

[Laserman532]

32 amps field max you should read 237 to 243 volts across the tube. 1 watt sounds good, clean your mirrors and brewesters

no your power supply is set to 32...i can tell you how to turn it to 38...but 35 is what I would reccomend
