Testing a glass laser tube without cooling

[Dan Hintz]

Re fridge mechanic has advised me and will setup a water chiller unit that will chill the water to -5 degrees if I want it to for App $500.00 Australian

Well, at that temp you'd be chilling solid ice Also, you do not want to chill the water too much or you'll start running into issues with the tube sweating... water and high-voltage are not a good mixture.

Probably should check the dew point temp and not chill below that
