A laser stimulated atom probe for atom probe imaging of dielectric and low conductivity semiconductor materials is disclosed. The laser stimulated atom probe comprises a conventional atom probe providing a field emission tip and ion detector arrangement, a laser system providing a laser short laser pulse and synchronous electronic timing signal to the atom probe, and an optical system for delivery of the laser beam onto the field emitting tip apex. The conventional atom probe is employed in a manner similar to that used for investigation of high conductivity materials. However, the electric field is held static while the laser is pulsed to provide pulsing of the ion emission rate. The laser pulsing is accomplished in a manner similar to prior implementations of pulsed laser atom probe spectroscopy. The laser pulses provide a trigger signal to enable recording the time of flight in the atom probe. The laser operates at a wavelength in the UV in order to enhance the optical absorption in semiconductor or dielectric field emission tips. The increased optical absorption allows efficient thermal pumping of the field evaporation rate. The tip apex field is also used to redshift the optical absorption spectra of the dielectric or semiconducting material under investigation, further enhancing the optical absorption. Due to the enhanced absorption, it is also possible to realize a photo ionization mechanism, wherein the laser stimulates electronic transitions from the more extended surface atoms, thereby ionizing the surface atom. The laser source is collimated by a collimation lens, reflected using dielectric mirrors, directed onto the sample tip using a focusing lens arrangement, collected from the tip using a collection lens, and directed into a beam stop. The laser beam diameter at focus is approximately 3-30 microns, thus, individual emission tips may be scanned from a field of tips illuminated by the laser pulse.
