1. A method, comprising:
forming a first voxel at a first position in a substrate using a first laser pulse;
detecting light emitted or scattered by the substrate as a result of forming the first voxel;
determining whether the detected light satisfies a predetermined constraint;
in response to determining that the detected light does not satisfy the predetermined constraint, adjusting an amplitude of a second laser pulse.
