A near-field scanning optical microscope (NSOM) laser micromachining
system for laser machining features on surfaces using an ultrafast laser
source and a method of laser machining such features. The system
includes: the ultrafast laser source to generate pulses of laser light
having pulse durations less than 1 ns and a peak wavelength; an NSOM
probe having a substantially cylindrical shape; an NSOM mount to
controllably hold the NSOM probe and the microstructure workpiece to be
machined; an NSOM probe monitor coupled to the NSOM mount for determining
the distance between the probe tip of the NSOM probe and the surface; and
an NSOM controller coupled to the NSOM probe monitor, and motion stages
in the NSOM mount. The NSOM mount includes an XY motion stage and a Z
motion stage. These motion stages are couple to either the NSOM probe or
the microstructure workpiece, or one motion stage to each.
