Abstract: Systems and methods for remediating streak in glass ribbons formed from glass forming processes are disclosed. The systems include a laser that produces a stationary laser beam having a wavelength of from about 1 μm to about 12 μm and a beam width less than or equal to a full width half maximum of a change in the thickness of the glass ribbon over a streak width at a streak location and optical components to condition and direct the laser beam at the streak location. The methods include forming the glass ribbon, identifying a streak in the glass ribbon, and directing the laser beam at the streak location. The laser beam heats the glass ribbon at the location of the streak, which reduces a viscosity of the glass ribbon to cause glass thinning that reduces the severity of the streak.
