I guess I'm not fond of liquids around my laser (unless de-i'd water)so I chose to fan cool mine. My approach to holography this time was to build my camera with the least amount of limitations or headaches in the system so I could concentrate on herding photons! The fan does not cause any stability problems according to my interferometer.

Although I am doing single beam holograms, my mirror is mounted on a set of the Blox by Lenox Laser which allows me to have a full 90 degree tilt up and down to the mirror. I have those Blox mouned on the mount from a photographic enlarger (the interface between the pole and the enlarger head) which allows the mirror to be moved up and down and side to side.
