Hi ElektroFreak, Yes, I work for CrystaLaser. crystalaser does not make laser pointers. However, crystalaser manufactures compact lasers for educational, scientific and industrial applications.

I think the blue or violet LED may do a better job. Laser may be good for selected, very special wavelength, then can be a highly efficiency tool for biomedical application

Scattering causes the side view of a laser beam. Shorter wavelength laser beam cause stronger scattering than longer wavelength laser beam.

1W 808 nm laser is a class 4 laser. it is harmful. it will burn the skin and eye and it is invisible so it is more danger than the visible light in some point. The green or violet laser will cause fires faster than the 808 nm laser. it is also transmit more to human body so it is not like green...
