Numerical Modeling of Optical Parametric Chirped Pulse Amplification to Design a Petawatt Laser Front End
A numerical model of optical parametric chirped pulse amplification (OPCPA) was developed and used to investigate two designs for the front end of a proposed petawatt laser, which is a very high intensity laser. A petawatt laser is required for fast ignition, a new technique that has the potential to greatly benefit the study of Inertial Confinement Fusion (ICF) and is being investigated at var...
متن کاملNumerical Simulation of an Intense Isolated Attosecond Pulse by a Chirped Two-Color Laser Field
We investigate theoretically the high-order harmonic spectrum extension and numerical generation of an intense isolated attosecond pulse from He+ ion irradiated by a two-color laser field. Our simulation results show that the chirp of the fundamental field can control HHG cutoff position. Also, these results show that the envelope forms of two fields are important factors for controlling the re...
متن کاملChirped pulse laser sources and applications
This paper presents recent results in the development of novel ultrafast technologies based on the generation and application of extremely chirped optical pulses. Linearly frequency-swept modelocked optical pulses of ns durations are generated, at the infrared telecommunications wavelength of 1.55 mm, by using chirped fiber Bragg gratings. The swept pulses appear as continuous wave signals, whi...
متن کاملThe Chirped-pulse Inverse Free-electron Laser
We propose a new accelerating concept, the chirpedpulse inverse free-electron laser (CPIFEL). We study the inverse free-electron laser (IFEL) accelerator both theoretically and computationally, and show that by using a femtosecond (fs), ultra-high-intensity drive laser pulse, the IFEL interaction bandwidth and accelerating gradient are increased, thus yielding large energy gains. Using a chirpe...
متن کاملRepetitive petawatt-class laser with near-diffraction-limited focal spot and transform-limited pulse duration
A repetitive petawatt-class Ti:sapphire laser system operating with high spatial and temporal beam quality is demonstrated. Maximum pulse energy of 30 J is obtained via five multi-pass amplification stages. Closed-loop feedback control systems in the temporal and spatial domains are used to yield Fourier-transform-limited pulse duration (33.7 fs), and diffraction-limited focal spot sizes (with ...
