Ablation characteristics of ultrashort laser pulses were investigated for pulse durations in the range of 130 fs-10 ps. Tissue samples used in the study were dental hard tissue (dentin) and water. We observed differences in ablation crater morphology for craters generated with pulse durations in the 130 fs-1 ps and the 5 ps-10 ps range. For the water experiment, the surface ablation and subsequent propagation of stress waves were monitored using Mach-Zehnder interferometry. For 130 fs-1 ps, energy is deposited on the surface while for longer pulses the beam penetrates into the sample. Both studies indicate that a transition occurs between 1 and 5 ps.

“…In dentistry, the aim of this technology is to ablate oral hard and soft tissues with minimal collateral damage and high precision at sufficient ablation rates (Altshuler et al 1993). Accurate preparation outlines and the lack of thermal damages around the prepared cavities suggest the use of USPL technology in dentistry.…”

The aim of this study was to assess heat generation in dental restoration materials following laser ablation using an Ultra Short Pulse Laser (USPL) system. Specimens of phosphate cement (PC), ceramic (CE) and composite (C) were used. Ablation was performed with an Nd:YVO 4 laser at 1064 nm and a pulse length of 8 ps. Heat generation during laser ablation depended on the thickness of the restoration material. A time delay for temperature increase was observed in the PC and C group. Employing the USPL system for removal of restorative materials, heat generation has to be considered.

“…dentistry related applications [e.g. [8][9][10][11][13][14][15][16][17][18][19][20][21]. This can be easily understood due to anatomic specialties like the shape of the tooth, for example, only allowing rather limited blood circulation, which accordingly does not allow efficient removal of externally applied heat.…”

Direct-writing techniques are adequate tools for rapid prototyping of diverse materials, since they avoid the usage of moulds or masks. Among them, laser-induced forward transfer (LIFT) has become a promising tool for rapid prototyping of microdevices due to the high focusing power of lasers, which provides a high resolution, and also to their non-contact and orifice-free nature, which avoids clogging and thus allows working with a wide range of materials. This makes LIFT an appropriate tool for biosensors preparation. In this article, immunoglobulin (IgG) microarrays were prepared through LIFT varying the laser pulse energy. It was found that there exists a minimum energy threshold, E min , below which no material is deposited. Moreover, an analysis of the droplets volumes revealed a linear dependence of this parameter with the laser pulse energy, what allowed finding the existence of an energy density threshold, which is considered to be the threshold to generate an impulsion on the liquid film that only results in droplet ejection when the total energy overcomes E min . Finally, the bioactivity of the transferred proteins was tested, showing no loss of their activity along the whole laser pulse energy range.
