LASER PULSE CORRELATION: A METHOD FOR DETECTING SUBTLE TOPOGRAPHIC CHANGE USING LIDAR RETURN WAVEFORMS
LIDAR laser altimetry waveforms natural hazards surface deformation
<
2015/3/10
We present a technique for using the recorded laser return pulse as a raw observation to detect centimeter-level vertical topographic change from large footprint airborne and spaceborne laser altimetr...
LASER PULSE VARIATIONS AND THEIR INFLUENCE ON RADIOMETRIC CALIBRATION OF FULL-WAVEFORM LASER SCANNER DATA
Radiometric Calibration Full-Waveform Laser Scanning Error Assessment
<
2014/6/5
Full-waveform laser scanning extends the information content of "conventional" laser scanning by storing the temporal profile of both the emitted laser pulse and its echoes. This allows for calc...
Highly efficient electrospray process for carbon nanotube- based laser pulse formers
Nanomaterials Nonlinear optical devices Mode-locked laser
<
2015/6/9
We demonstrate laser pulsation of CNTs deposited by electrospray process that ensures target-localized and homogeneous deposition of CNTs with dramatically improved deposition efficiency (>95%). Resul...
Laser Pulse Compression and Amplification by Stimulated Backward Raman Scattering of Ba(NO3)2 and CaCO3 Crystals
Laser pulse compression Stimulated backward Raman scattering Short pulse laser
<
2009/6/15
Pulse compressor and amplifier using stimulated backward Raman scattering (SRS) of barium nitrate and calcite crystals are studied experimentally. 15 times of compression and more than 50 % SRS reflec...
Filamentation and Energetic Electron Generation in a Plasma Produced from a High Density Gas Jet Irradiated by a TW Laser Pulse
Energetic electron beam Filamentation TW Ti:sapphire laser pulse
<
2009/6/15
Emission of a well-collimated energetic electron beam has been observed from a plasma of which electron density is higher than 1020 cm-3 produced by a TW Ti:sapphire laser pulse. The maximum energy of...
Generation and Application of Ultrashort Electron Beam Driven by an Ultrashort Intense Laser Pulse
Laser wakefield acceleration TW laser Plasma wave
<
2009/6/15
Recently, it is strongly required to develop ultra-short electron beam sources for ultra-fast probe analysis of matter. Among a number of concepts of ultra-short electron bunch production the laser wa...
Processing of Biomedical Tissue Materials by Femtosecond Laser Pulse
Femtosecond laser Hydroxyapatite Laser ablation
<
2009/6/8
The micromachining of hydroxyapatite (HAp) and collagen is highly required for orthopedics and dentistry, because human bone and tooth consist mainly of HAp oriented along the collagen. We have evalua...
Nano-processing Utilizing Plasmon on Glass Surface by Femtosecond Laser Pulse with Template of Dielectric Particle Array
Femtosecond laser Nano-processing Nano-particle
<
2009/6/1
Nano-processing using a near-field generated by laser irradiation onto the nano-particle is becoming a new emerging nanofabrication technology, because it can fabricate nano-sale structures even with ...
Generation of Fiber Tunable High-power Picosecond Laser Pulse
Fiber laser Fiber amplifier Picosecond laser
<
2009/6/1
A fiber tunable high-power picosecond laser system has been for the first time demonstrated. A gain switch semiconductor laser diode was introduced as seed source, and a multi-stage single mode Yb-dop...
