Talking Newcomer from US

Hello all, my name is Charles. I’m from California. After browsing this forum for a few months, I’ve decided that I want to get in on the action. I’m new to lasers, but look forward to learning more and getting to know everyone. I have an affinity for small hosts and blue wavelengths, so if you have any recommendations, let me know.

Thanks for reading!

If I wanted to build a laser, what would I need other than a module from DTR(diode+driver) and one of Survival Laser's host kits(like this https://www.survivallaserusa.com/DTR...7736986.aspx)?

Soldering station and solder, heat shrink tubing and rechargeable Li-ion Battery(ies). Oh, and a lens. Either a multi-element lens or his(DTR) G2. The module comes with a stock acrylic lens which you will want to change for a glass one.
