In March 2014, the 50 Watt FORT laser had terrible lifetimes. There are some pictures that should be in the Z drive. Now, after buying the new FORT laser, May 2014, they look much more reasonable. wtf? The one thing I did differently was put the laser through a beam cube and aligned the cavity mirrors to maximize the linearly horizontal polarized light.
-Possible explanation would be that there was a loose mirror in cavity??
-Maybe I was leaving a laser on when I took the data in March??
