    Default Long-term storage issues with DPSS lasers?

    Does anyone know of any detrimental effects of storing DPSS lasers, unused, for several months at a time? If I remember correctly, some gas lasers (25 years ago!) pretty much died if they sat unused too long, and I'm hoping that doesn't effect DPSS as well.

    Unfortunately this might be a real concern of mine for a few more years!

    Thanks!

    Mine was sat unused for 8 - 12 months +.

    Ran it the other day for a few mins, looks fine, bright etc.

    Gas tubes go 'high pressure' when stored unused. I haven't ever heard of problems with dpss; its a crystal that remains unaffected by time unless enviromental conditions are extreme (condensation, air impurity and leaks, etc.)

    Default dpss/gas laser

    dpss laser don't have the same flaws with storage a a gas lasers do although i had my 60x argon siting for almost a year and was lucky enough that it still ran if you do happen to let a gas laser sit for a long time it will go high pressure but if you are lucky enough that it still starts even if dim you can run it back down to the correct pressure (and if it wont start at all you can force start it with a Tesla coil) and then run it back down to pressure
