UCF Researchers Set Record Fastest Light Pulse
2017/9/4
A research team at the University of Central Florida has demonstrated the fastest light pulse ever developed, a 53-attosecond X-ray flash.The group led by Professor Zenghu Chang beat its own record se...
APPLICABILITY OF FIRST PULSE DERIVED DIGITAL TERRAIN MODELS FOR BOREAL FOREST STUDIES
DTM quality first pulse last pulse laser scanning TIN grid
2015/8/13
Detailed high-resolution digital terrain models (DTM) can be obtained using airborne laser scanner data. This paper evaluates the
accuracy of DTM derived from first return of laser scanner data for f...
FROM SINGLE-PULSE TO FULL-WAVEFORM AIRBORNE LASER SCANNERS: POTENTIAL AND PRACTICAL CHALLENGES
Laser scanning Digitisation Retrieval Vegetation
2015/6/1
Airborne laser scanning, often referred to as lidar or laser altimetry, is a remote sensing technique which measures the round-trip
time of emitted laser pulses to determine the topography of the Ea...
Optical dipole force on ladder-like three-level atomic systems driven by chirped few-cycle-pulse laser fields
Optical dipole force ladder-like three-level atomic systems chirped few-cycle-pulse laser fields Optics
2012/5/17
We report a study on the optical dipole force in a ladder like three level atomic systems in the context of coherent population transfer with the chirped few-cycle-pulse laser fields. The phenomenon o...

Spectral Bandwidth Reduction of Thomson Light Pulse Chirping Optics
2012/4/19
Based on single particle tracking in the framework of classical Thomson scattering with incoherent superposition, we developed a fully relativistic, three dimensional numerical code that calculates an...
An Optical Fibre Pulse Rate Multiplier for Ultra-low Phase-noise Signal Generation
Optical Fibre Ultra-low Phase-noise Signal
2011/9/6
In this letter we report on an all optical-fibre approach to the synthesis of ultra-low noise microwave signals by photodetection of femtosecond laser pulses. We use a cascade of Mach-Zehnder fibre in...
Semianalytic theory of self-similar optical propagation and mode locking using a shape-adaptive model pulse
Semianalytic shape-adaptive model pulse
2011/9/1
A semi-analytic theory for the pulse dynamics in similariton amplifiers and lasers is presented,based on a model pulse with adaptive shape. By changing a single parameter, this test function can be co...
We consider a general problem of laser pulse heating of spherical metal particles with the sizes ranging from nanometers to millimeters. We employ the exact Mie solutions of the di raction problem and...
Time-resolved quantitative multiphase interferometric imaging of a highly focused ultrasound pulse
Time-resolved quantitative multiphase interferometric imaging ultrasound pulse
2010/11/16
Interferometric imaging is a well established method to image phase objects by mixing the image wavefront with a reference one on a CCD camera. It has also been applied to fast transient phenomena, m...
Hawking radiation from ultrashort laser pulse filaments
Hawking radiation ultrashort laser pulse filaments
2010/10/27
Event horizons of astrophysical black holes and gravitational analogues have been predicted to
excite the quantum vacuum and give rise to the emission of quanta, known as Hawking radiation.
We exper...
Limits on Preserving Quantum Coherence using Multi-Pulse Control
Limits Preserving Quantum Coherence Multi-Pulse Control
2010/10/19
We explore the physical limits of pulsed dynamical decoupling methods for decoherence control
as determined by finite timing resources. By focusing on a decohering qubit controlled by arbitrary seque...
Nuclear Collective Excitation by a Short Strong Laser Pulse
Nuclear Collective Short Strong Laser Pulse
2010/10/27
We derive the conditions on the average laser energy and the mean photon number such that
a strong short laser pulse causes collective nuclear excitation. We use the nuclear Giant Dipole Resonance as...
Generation of 1.5 µm Squeezed Vacuum Pulse Using a Sagnac Loop Interferometer
Squeezed state Ultrafast nonlinear optics
2009/6/1
Photon-number squeezing and quadrature squeezing were studied using ultrafast fibre nonlinear optics pumped by 1.5 µm femtosecond laser pulses. To obtain quadrature squeezing using an Erbium dop...
