Welcome to the LPF. Safety first always. If I were you I'd purchase a 532nm DPSS laser pointer on eBay first. The 301 or 303 can be had for as little as $6. They typically run around 80 mW, but you can never be sure unless you have a calibrated laser power meter. I have many of these in my collection and they are a great green laser pointer to own.
