The 4 Types of Fiber Lasers
Braden Todd of Glassmith2 explains fixed pulse, MOPA, flying optic, and galvo lasers.
Fixed pulse width and MOPA: The fixed pulse width machine cannot be adjusted whereas the MOPA systems allow the user to adjust the pulse width for maximum marking options.
Flying optic and galvo: A flying optic is essentially a mirror and lens assembly that travels over the laser bed when engraving. A galvo system steers the beam through mirrors increasing marking speed with reduced markable area.
