It's been a long time since I did it in school but i do remember doing a holography lab that uses the white light of the room as the reference? beam to complete the hologram so it can be viewed at any time. If not you do need the laser to actually view the hologram as well if it is used for both the object and reference beams.

I'll see if i still have that stuff laying around anywhere and upload it. Note that it also takes a very stable optics table, a power meter so you can calculate the exposure time a decent amount of mirrors/mounts and the ability to develop the holographic plates... but it sure is fun!
