Hey, everyone. I'm new to the forums and very inexperienced with lasers. Any tips and helps to become more acclimated to the community are happily encouraged. I am studying electrical engineering at Villanova University and love physics.

Welcome and enjoy the forum.

Use the LPF Search function at the bottom of the page to access the LPF database of questions answered many times and also comments about same.

Always use laser glasses/goggles to protect eyes and use safe operating procedures for lasers

Welcome to the LPF. When I was in engineering school, physics was my favorite classes along with math, the language of physics. I still rely on my text books from then, though I've needed to update some as the technology has advanced. Stay safe and learn all you can. There is no substitute for knowledge.
