I have an interest in dye lasers but some of the gain media I'd like to try is very corrosive. Either the solutions themselves contain lots of chlorine ions, or need to be in an acidic solution to dissolve fully. I am intentionally vague on the fluids here because I want to use the same laser cavity for testing many fluids.
I would like to run the dye through a liquid to liquid heat exchanger to cool it with a regular chiller.
I so far am considering hard anodized aluminum (I can "clean up" any pores with high voltage in a baking soda solution) but am not super stoked for that idea due to the solubility of aluminum chloride. I considered a glass tube, which would work but would take a lot more surface area and therefore volume, and the liquids can be expensive. Stainless is an option, but I'm not so sure how well it will work and various platings are also possible. I know ceramics can have decently low thermal resistance, but I have a hard time finding hard data on actual available tubes.
The pumps and housings will be polypropylene and gaskets will be silicone.
Really just looking for some input in an area I am inexperienced in. The goal is a delta T of 10C max at around 100 watts average. Lower is preferred, as more power is more better, and that 10C differential is a condensation nuisance and potential freezing limit for certain operating conditions.
