    Any ideas why my green laser power increases

    Hi, I was checking my green laser. It was 4.9 mW in the winter. Now it's varies output 7mW and maximum of 8mW. I added an IR filter and found that it returned back to 4.9mW so, probably there is IR leakage of approximately 3 to 4mW. I'm not sure if that makes the pointer danger or not. 4mW of...
