    Abstract: One embodiment of the present invention can be characterized as a method for controlling a multi-axis machine tool that includes obtaining a preliminary rotary actuator command (wherein the rotary actuator command has frequency content exceeding a bandwidth of a rotary actuator), generating a processed rotary actuator command based, at least in part, on the preliminary rotary actuator command, the processed rotary actuator command having frequency content within a bandwidth of the rotary actuator and generating a first linear actuator command and a second linear actuator command based, at least in part, on the processed rotary actuator command. The processed rotary actuator command can be output to the rotary actuator, the first linear actuator command can be output to a first linear actuator and the second linear actuator command can be output to a second linear actuator.

    Abstract: A method for forming a through-via in a substrate having opposing first and second surfaces can include directing a focused beam of laser pulses into the substrate through the first surface of the substrate and, subsequently, through the second surface of the substrate. The focused beam of laser pulses can have a wavelength to which the substrate is at least substantially transparent and a beam waist of the focused beam of laser pulses is closer to the second surface than to the first surface. The focused beam of laser pulses is characterized by a pulse repetition rate, a peak optical intensity at the substrate and an average power at the substrate sufficient to: melt a region of the substrate near the second surface, thereby creating a melt zone within the substrate; propagate the melt zone toward the first surface; and vaporize or boil material of the substrate and located within the melt zone.

    Abstract: A beam positioner can be broadly characterized as including a first acousto-optic (AO) deflector (AOD) operative to diffract an incident beam of linearly polarized laser light, wherein the first AOD has a first diffraction axis and wherein the first AOD is oriented such that the first diffraction axis has a predetermined spatial relationship with the plane of polarization of the linearly polarized laser light. The beam positioner can include at least one phase-shifting reflector arranged within a beam path along which light is propagatable from the first AOD. The at least one phase-shifting reflector can be configured and oriented to rotate the plane of polarization of light diffracted by the first AOD.
