Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
Sub-femtosecond absolute timing precision optics
2012/5/29
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...
Generating Molecular Rovibrational Coherence by Two-Photon Femtosecond Photoassociation of Thermally Hot Atoms
Generating Molecular Rovibrational Two-Photon Femtosecond Photoassociation Thermally Hot Atoms
2011/8/18
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...
Femtosecond pulses in a dense two-level medium: Spectral transformations, transient processes, and collisional dynamics
Femtosecond pulses dense two-level medium Spectral transformations transient processes collisional dynamics
2011/8/5
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...
Third and fifth harmonics generation by tightly focused femtosecond pulses at 2.2 μm wavelength in air
harmonics focused femtosecond pulses
2011/9/6
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...
Temperature-dependent chirped coherent phonon dynamics in Bi$_{2}$Te$_{3}$ using high intensity femtosecond laser pulses
Temperature-dependent chirped coherent phonon dynamics femtosecond laser pulses
2010/11/18
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 ∼...
Compressive auto-indexing in femtosecond nanocrystallography
Compressive auto-indexing femtosecond nanocrystallography
2010/11/16
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...
Design of Smith-Purcell emitter in femtosecond accelerator
THz source Smith-Purcell radiation coherence optimization
2009/8/14
Based on the femtosecond accelerator device, we are planning to build a broad band and tunable THz source using the Smith-Purcell radiation mechanism. Coherent Smith-Purcell radiation could be achiev...
Direct Ionization Desorption of Fullerene by Intense Femtosecond Laser Fields
C60 Solid Femtosecond Ionization
2009/6/1
We investigated the direct ionization and desorption of solid C60 by the irradiation of femtosecond nonresonant (neutral and cationic states) pulses at 1.4 µm. We concluded that ion desorption i...
