I'm taking a public speaking course and our first speech is just an informative one. I intend to teach the class a little bit about how lasers work. This is next month and I want to have a laser with significant power (1 to 2 Watts) to use as a visual aid. I already have a 20mW 405nm laser gun that I made a while ago. I've had a plan to get a jayrob host kit and a 445 diode from one of the people recommended and now I'm going to push that plan up. My questions for the community are:
What are your recommendations for the diode I should get? I've been reading around but more information couldn't possibly hurt.
What are some good ways to ensure a safe display other than getting cheap goggles to distribute to the class?
