1. A laser system comprising:
a laser configured to emit laser pulse bursts; and
a motion device in optical communication with said laser and configured to deliver said laser pulse bursts to a plurality of spaced apart locations along a substrate to form a laser induced channel in the substrate at one or more of said plurality of spaced apart locations;
wherein said motion device has a natural frequency greater than an operating frequency of the laser system to prevent resonant vibration when the motion device operates to change delivery location of the laser pulse bursts among said plurality of spaced apart locations at a constant speed.
