Hey, I just got a cool idea We could use pain as a way to test lasers for those without power meters How much pain you feel could give a rough idea of output power!
Of course, people feel pain differently. We'll calibrate it with a swift kick in the nuts! ;D
Edit: It isn't that difficult to re-align the crystals in the RPL's. But you probably wouldn't want to mess with the warantee. I've already adjusted mine twice and got it even more powerful then when I first got it!
This is actually one of my methods of measuring the performance of my RPL. It veries depending on temprature, and I'm calibrated to my personal pain expatations of my specific unit, so when It hurts more quicker, I'm like "yes!" But when it burns less slower, I'm like "awe!" Then I usually wait till it warms up, then I'm like "ouch!, yes!" Not sure how the pain will match from a swift kick to the nuts to that of a burning laser...maybe calibrate the burn to your nut sack's skin because it's more sensitive then your hand or arm! ;D
