500mw laser?!






500mW of 532nm would be unbelievably bright and would cost hundreds of dollar minimum
 
not really. for $60 you could buy an ebay green pointer and then shine it through some rotating diffraction gratings to get the same effect and still have $50 dollars left. If you want to see a cool light show check out some of the RGB laser show projectors on this site and photonlexicon. They make that projector look like the overpriced paper weight/door stop that it really is.
