I just got my first laser from China. It was a 50w 4040. I finally got it set up and all the electronics worked and when I finally went to test fire and calibrate the mirrors....Nothing happened.....The test fire LED lit up...The Power supply led lit up and all I heard was a power sizzle....I did a hard look at the tube and saw some weird pieces....Does it look this piece is broken? These is another similar chunk on the on the other side too that looks the same. Thanks for any help I can get.
