Embodiments of this invention generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for creating synchronized three-dimensional laser incisions. In an embodiment, an ophthalmic surgical laser system comprises a laser delivery system for delivering a pulsed laser beam to a target in a subject's eye, an XY-scan device to deflect the pulsed laser beam, a Z-scan device to modify a depth of a focus of the pulsed laser beam, and a controller configured to synchronize an oscillation of the XY-scan device and an oscillation of the Z-device to form an angled three-dimensional laser tissue dissection.
