Actually looked into this very option years ago and found it to be not feasible for these reasons:
1. Its expensive technology as the laser diode needs driver and power supply.
2. Issues of laser classified safety would ban usage in most public places.
3. The power required is more than an RC battery could deliver.
4. These devices get very hot and would melt plastics they are mounted in.
5. Laser diodes are fragile and sensitive to shock.
