There is a book called _The Laser Cookbook_ which describes some circuits
for driving galvos (usually just a 741 driving a complimentary pair of
medium-power transistors).

For those of you designing a laser show, I reccommend the AD7226 quad
8-bit D/A converter.  It saves you from having to have a large number of
D/A chips, opamps, and latches since it has all of that built in.
(i.e. voltage mode D/A).
