A photothermal displacement method has been developed to probe the pulsed laser-induced transient melting and surface deformation of Ni–P hard disk substrates. A probing He–Ne laser beam is aligned collinearly with the near-infrared nanosecond pulsed heating beam. The He–Ne beam spot is scanned on the microfeatures formed on the sample surface by the pulsed laser heating. The deflection signals show the variation of the feature shape resulting from different pulse energies of the heating laser beam. The transient deflection signal also reveals that the time scale of the surface motion is in the range of several hundred nanoseconds.

The thermodynamics of the rapid boiling of a liquid on a solid surface heated by an excimer laser pulse is studied experimentally. The dynamics of bubble nucleation, growth, and collapse is detected by probing the optical specular reflectance. The transient temperature field is measured by monitoring the reflectance of a thin film with calibrated optical properties. The metastability behavior of the liquid and the criterion for the liquid‐vapor phase transition in nanosecond time scale are obtained for the pressure from 1 atmosphere to 3.3 MPa.

The transient temperature field development during heating of an amorphous silicon (a‐Si) film, deposited on a fused quartz substrate by pulsed excimer laser irradiation is studied. Experimental optical transmission data are compared with heat transfer modeling results. The temperature‐dependence of the material complex refractive index through the thin film thickness is taken into account.

Organic material direct writing was demonstrated based on nanomaterial enabled laser transfer (NELT). Through proper nanoparticle size and type, and the laser wavelength choice, a single laser pulse could transfer well defined and arbitrarily shaped tris-(8-hydroxyquinoline)Al patterns ranging from several microns to millimeter size. The unique properties of nanomaterials allow the laser induced forward transfer process to be effected at irradiation energies and temperatures lower than commonly used. The technique may be well suited for the mass production of temperature sensitive devices.Organic material direct writing was demonstrated based on nanomaterial enabled laser transfer (NELT).
