Four volcanic glass samples on the INternational focus group on Tephrochronology And Volcanism (INTAV) sample mount described by Kuehn et al. (2011) were analyzed to establish a new methodology for m...
We report high-resolution in situ Pb isotope analysis (207Pb/206Pb and 208Pb/206Pb ratios) by femtosecond laser ablation-multiple ion counter-inductively coupled plasma-mass spectrometry (fsLA-MIC-IC...
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we demonstrate 10 GHz si...
We investigated carrier-relaxation dynamics of femtosecond laser annealed (FLA) polycrystalline silicon (poly-Si). The correlation between morphology and electrical properties of poly-Si after femtose...
Abstract: The formation of diatomic molecules with rotational and vibrational coherence is demonstrated experimentally in free-to-bound two-photon femtosecond photoassociation of hot atoms. In a therm...
Abstract: Propagation of ultrashort optical pulses in a dense resonant medium is considered in the semiclassical limit. In our analysis, we place emphasis on several main points. First, we study trans...
We report experiments on the generation of third and fifth harmonics of millijoule-level, tightly focused, femtosecond laser pulses at 2.2 μm wavelength in air. The measured ratio of yields of the thi...
The ablation protocols for 200 nm ultra violet-femtosecond laser ablation (200FsLA)—inductively coupled plasma mass spectrometry (ICPMS) have been examined using a quadrupole ICPMS and applied to zir...
Degenerate pump-probe reflectivity experiments have been performed on a single crystal of bismuth telluride (Bi2Te3) as a function of sample temperature (3K to 296K) and pump intensity using ∼...
Ultrafast nanocrystallography has the potential to revolutionize biology by enabling structural elucidation of proteins for which it is possible to grow crystals with 10 or fewer unit cells on the sid...
A novel system for the RF synchronization is presented. It makes use of standard, commercially-available telecommunication optical components. The added timing jitter of 5 fs RMS has been measured on ...
We investigate the focusing properties of a femtosecond vortex light pulse focused by a high numerical aperture objective. By using the Richards-Wolf vectorial diffraction method...
The purpose of this study was to evaluate the feasibility of using a femtosecond pulse laser processing technique to store information on a dental prosthesis. Commercially pure titanium plates were pr...
We have demonstrated a combined imaging system, where the physiology of biological specimens can be imaged and profiled at 10–20 frames per second whilst undergoing femtosecond laser irradiation. Indi...
A study demonstrating how ultrafast laser radiation stimulates osteoblasts is presented. The study employed a custom made optical system that allowed for simultaneous confocal cell imaging and targete...
