Is there any reason you have to use a laser? Optical data transmission can be done with high powered LEDs as well where the dangers and most prominently the focusing and alignment issues are greatly relaxed. I've done free space optical communications (laser data links) before and found that at any reasonable distance (even 75ft) the alignment becomes a nightmare even with "stable" equipment setups (professional tripods, etc). Unless you've got a precision gimbal or other XY adjustment methods you're going to have a very hard time with using a laser link.
