Hey im looking for a laser like the one made out of a dvd laser. but i do not have the time as of now to build it. i would like to get one for physics because most people think lasers are useless and i would like to show them first hand what light can do* i am looking for a laser with about 200-300mw red or green would be fine.
I am looking for one around 200 dollars or less. thanks ahead of time
