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...
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...
Properties of the 1/cosh(t) Laser Pulse, Supersymmetry, and the sine-Gordon Equation
Properties of the 1/cosh(t) Laser Pulse Supersymmetry sine-Gordon Equation
2011/1/21
In this Letter, we explain a well-known but little understood effect in Laser Physics: when a
two-level atom, initially in the ground state, is subjected to a 1/ cosh(t) laser pulse, it remains in th...
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...
