“…Photograph of the liquid cell is shown in Figure 2. Beam deflection set-up, (Alti & Khare 2006a, 2006b shown in Figure 1, was used to measure cavitation bubble and charge-particle velocity. The second harmonic of Q-switched Nd: YAG laser (HYL-101) was focused with 15 cm lens into the liquid cell filled with de-ionized distilled water (conductivity , 1 mV 21 ).…”

“…Understanding the basic principles of coupling between laser radiation and surface [16] is necessary in developing industrial and medical applications of laser beams, both at low levels and high levels of impact, ranging from texturing to ablation [17][18][19]. Very often, accompanying processes and interactions with the plasma usually formed in front of the target [20] are as important, too.…”

Interaction of a Nd:YAG laser, operating at wavelengths of 1064 nm (23.6 J cm 22 fluence) or 532 nm (25.9 J cm 22 fluence), and pulse duration of 40 ps, with a titanium-based medical implant Ti6Al4V alloy was studied. Surface damage thresholds were estimated to be 0.9 J cm 22 and 0.25 J cm 22 at laser wavelengths 1064 nm and 532 nm, respectively. At both laser wavelengths, the energy absorbed was mostly converted into thermal energy, forming craters, albeit about 50 times deeper at 1064 nm than at 532 nm. Periodic surface structures (PSS) were also formed with both laser wavelengths, concentric, and radial at micrometer scale (3 mm to 15 mm period), parallel at nanometer scale (800 nm period with the 1064 nm laser, 400 nm with the 532 nm laser). In the case of the 532 nm laser, the concentric structures enlarge their period with accumulating laser pulse count. These features can help roughening of the implant surface and improve bio-compatibility.

Sculpted pulsed indium atomic beams via selective laser ablation of thin film

Abstract: We present a novel experiment for the generation of sculpted pulsed indium atomic beams of regular arrays in one and two-dimensions via rear side ablation of indium by two and four beams interference pattern using second harmonic of high power Nd: YAG laser under high vacuum~10 Ϫ5 Torr!.
