Hi David and Martin,
Thanks for your comment. I'm curios to know which Ar/Kr you were using.
I know at least two Coherent heads that are running on the same tube for
several thousands of hours and for over 10 years.
I totally would prefer solid state but I need 4-5 lines with high power
(150-250mw) and the solid state at these intensities are super
expensive. Overall I will be paying about double for a solid state set
and I just can't afford it.
Would love to hear more and get tips for extending their life...
Yuval
