Wouldn't that be 5 mW instead of 5W? Or are we talking about totally different thingsA 5W red laser diode with lens is safe enough and commonly available and will make a good bright spot 50ft to 200ft, although the spot will get larger at 200ft of course.
Why not buy a $10 red laser pointer from ebay and do some initial tests?
373nm and 473nm wavelengths are 100nm apart.quick question, sorry so much question im just finding my way round this laser project. what the difference between a single mode laser and a multimode, and also what is the difference between a 375nm and a 473 wavelenght
