Dorothea,
Not only the H2O pressure is important, but also the H2O flow in the
cooling system. If the H2O flow is close to the required minimum the
laser will act like you have described. Check your cooling system on
obstacles that can down regulate the H2O flow and keeping the H2O
pressure on a "normal" level. We have seen the same problem in our
cooling system after inserting two other lasers for a new flowcytometer.
We could keep the H2O pressure on a "normal" level, but we could not
start the third laser for the reason described here.
