... I'm using fiber-lasers with 1070nm wavelength and much better beam-quality (smaller possible spot diameter) than a CO2-laser.
This cheapish chinese galvo-scanners and drivers aren't really meant for precise application, but your image shows a totally 'overdriven' system ... try to reduce the scanning speed to something around 15kpps or even lower.
My galvos were stated as 25kpps-types, but were only usable with max. 20kpps.
And with the servos as scanner motors I'm much slower than with galvos (something around 1m/s compared to 20m/s) but much more accurate/precise and beter suited for high power laser applications ...
