Subject: CO2 polishing improves the Q !! 

The plot below shows that the Q values of S1600439 improved a lot after the CO2 laser polishing. About 15 modes have Q above 10e6. The first mode at 1kHz has a Q of 37e6, the highest ever measured so far!

Here's a comparison of the Q values of this sample before annealing, after annealing and after CO2 polishing.
