Numerical simulations of ultrasimple ultrashortlaser-pulse measurement.
We numerically simulate the performance of the ultrasimple frequency-resolved-optical-gating (FROG) technique, GRENOUILLE, for measuring ultrashort laser pulses. While simple in practice, GRENOUILLE has many theoretical subtleties because it involves the second-harmonic generation of relatively tightly focused and broadband pulses. In addition, these processes occur in a thick crystal, in which...
متن کاملUltra-broadband Phase-matching Ultrashort- Laser-pulse Measurement Techniques
Dedicated to my wife, Seonghee Jeong, and my parents iv ACKNOWLEDGEMENTS I wish to thank all people who helped me in many different ways during my graduate school years. First of all, I would like to especially thank Rick Trebino not only for sharing his knowledge and experience since the beginning, but also for his constantly encouraging and motivating me, which could make this thesis possible...
متن کاملSensitive ultrashort pulse chirp measurement.
The chirp of an ultrashort laser pulse can be extracted with high accuracy from a modified spectrum auto-interferometric correlation waveform by using a new time domain algorithm that allows signal averaging. We display results revealing high sensitivity to chirp even with signal-to-noise levels approaching unity. Correction algorithms have been developed to accommodate signal distortion arisin...
متن کاملElectron in the Ultrashort Laser Pulse
After the clasical approach to acceleration of a charged particle by δ-form impulsive force, we consider the corresponding quantum theory based on the Volkov solution of the Dirac equation. We determine the modified Compton formula for frequency of photons generated by the scattering of the δ-form laser pulse on the electron in a rest.
متن کاملHawking radiation from ultrashort laser pulse filaments.
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 experimentally create such a gravitational analogue using ultrashort laser pulse filaments and our measurements demonstrate a spontaneous emission of photons that confirms theoretical predictions.
