Laser Scanning Actuators are mirror type optical scanners. It is capable of scanning at high speed and with high precision. These are used for communication equipment, inspection instruments, measuring instruments and printed baseboard processing equipment.

Laser Scribing is used to provide more accurate control to the final curvature of the slider. A laser focused on the surface of the slider melts a small area of the ceramic, and the resolidification of this material results in residual stresses that produce a net curvature of the slider. This process is used in production. Using finite element analysis when calibrated with experimental results can predict the deflection generated by a laser scribe. It can be placed anywhere on the surface of the slider. It can predict deflections within 10% of experimental values and the results can be improved significantly using different calibrations for different scribing directions.

Laser sensors measures the distance along the emitted beam. They are based on laser mass spectrometry that can be applied to any sample, solid, liquid or gas. They use laser beams in conjunction with mass spectrometers, nuclear detectors and gas chromatographic techniques. Typically, laser beams hit targets and the backscattered light is collected and processed. Depending upon the way in which the wave is transmitted, laser sensors are classified as pulse detection or amplitude modulation. In the former, the distance is obtained from the time elapsed between the emission and the receipt of a pulse. In the latter, the lasers emit an amplitude-modulated wave, and the distance depends on the difference of the phase between the emitted and the received wave.
