hi everyone im just getting into lasers and have become very interested with them. i dont really know too much about them and i kinda get a little confused with all the big words in the sticky threads. can anyone help me the difference between the power of lasers. what makes a 300mw laser more powerful. is it just a different diode or do you also need a higher rated driver to push it. if anyone has been to burningman then you have seen those huge lasers that go across the sky im really looking to find information on those, all i seem to find is laser pointers and people burning stuff. im not really into burning stuff (yet) im more into expanding the beam into wide visible beams if anyone doesnt mind explaining a little bit i would appreciate it.
