Gregory, be extremely careful with 50 mW lasers. That light output is really dangerous. I would advise you to do all your experiments with a 5 mW laser diode. Although this is also not absolutely safe, it is 10 times less dangerous.
As long as the system is scanning, there will be no problem. But during building and experimenting you want to have the scanning off for adjusting and measuring. Then a 50 mW focussed beam is far too dangerous and 5 mW is also bright enough to see what is happening.
Then finaly, if everything is tuned up, you might construct a scanning detector, such that when the scanning stops for whatever reason, the laser is switched off automatically. After that precautions you might replace the laser for a 10 x brighter result. And NEVER bridge the built scanning detector safety.
