ABCD formalism and attosecond few-cycle pulse via chirp manipulation of a seeded free electron laser.
An ABCD formalism is identified to characterize a seeded Free Electron Laser (FEL) with three chirps: an initial frequency chirp in the seed Laser, an energy chirp in the electron bunch, and an intrinsic frequency chirp due to the FEL process. A scheme of generating attosecond few-cycle pulses is proposed by invoking an FEL seeded by high-order harmonic generation (HHG) from an infrared laser. ...
متن کاملOptical Pulse Distortion
Pulse distortion and shaping mechanisms play a significant role in optical fiber communication and sensing. In this thesis we shall investigate techniques which alleviate pulse deterioration due to polarization effects, and utilize large chromatic dispersion for system performance enhancement. We first demonstrate a method of mitigating polarization mode dispersion (PMD) in fiber optic communic...
متن کاملTime-gated Fourier-domain optical coherence tomography.
A novel optical coherence tomography (OCT) system is presented that combines Fourier-domain OCT with incoherent nonlinear time gating. By processing backscattered light in the optical domain, the user can select a restricted depth field of view for improved contrast and acquisition speed. This technique has the additional advantage that imaging is done in the infrared (approximately 1280 nm) bu...
متن کاملPerformance of fourier domain vs. time domain optical coherence tomography.
In this article we present a detailed discussion of noise sources in Fourier Domain Optical Coherence Tomography (FDOCT) setups. The performance of FDOCT with charge coupled device (CCD) cameras is compared to current standard time domain OCT systems. We describe how to measure sensitivity in the case of FDOCT and confirm the theoretically obtained values. It is shown that FDOCT systems have a ...
متن کاملLow-energy distortion-free femtosecond pulse laser inscription in coated, free-standing optical fiber
Low-energy, distortion-free femtosecond pulse laser inscription in coated freestanding fiber is demonstrated for the first time. Methodology features radial plane beamshaping to achieve optimal focusing and spot-like inscription within the fiber. Strong, firstorder fiber Bragg grating is achieved in coated single-mode fiber using only 50nJ pulse energy.
