ABSTRACT:
A scanning optical system including an optical source configured to generate an ultra-short light pulse, a dispersion compensation system disposed such that the ultra-short light pulse travels through the dispersion compensation system, an optical deflector configured to rotate about an axis such that the ultra-short light pulse is deflected through a scan angle, and an f-theta scan lens having a group delay (GD) variation versus relative pupil height and group delay dispersion (GDD) variation versus the scan angle that are substantially minimized. The f-theta scan lens is disposed such that the ultra-short pulse is incident on the f-theta scan lens.
