'''Things to Do/Check'''
Measure 780 power before and after cavity; see changes with cavity piezo
put in diffraction grating (check specs)
make "V" shape with pvc pipes
make "N" shape with pvc pipes
Take out lens and translate photodiode
 
 
 
'''6/10/14'''
Re-aligned the 780 and 1064 with the camera, but this did not make the 633 visible through the fiber. We re-walked the beams into the fiber, since it was fairly misaligned after yesterday's adjustments to the isolators. We still couldn't see 633 flashing though when ramping the cavity and with filters in place. The alignment to the prism was off after re-aligning to the fiber, so we set up a separate walk to the fiber and prism. We can't see any 633 now, but hopefully decoupling the fiber and prism will make it easier to optimize the signal once we find it again.
