By the way, I just learned a little more about the technical aspects of this laser from a tech at CNI. The 808nm laser diode in this laser has a maximum power output of 1W. Also, this laser is rated for 100% duty cycle at full power, so you can run it continuously without worrying about overheating it. I have run it for 5 minutes and didn't even notice the heatsink fins getting warm. The more I learn about this laser, the more impressed I am with it. I'm not just saying these things because I'm selling it either. This is an amazing little laser.
