Abstract The structural versatility of light underpins an outstanding collection of optical phenomena where both geometrical and topological states of light can dictate how matter will respond or display. Light possesses multiple degrees of freedom s

A long-sought-after goal for photocathode electron sources has been to improve performance by temporally shaping the incident excitation laser pulse. The narrow bandwidth, short wavelength, and picosecond pulse duration make it challenging to employ

A full start-to-end (S2E) software model of a laser system – including oscillator, amplifier, stretcher/compressor, pulse shaper, and non-linear conversion – can be essential in choosing the hardware design and establishing limitations on what ca

Ultralow phase-noise mode-locked lasers are crucial for real-world applications. We present two accomplishments: (1) short-term FF CEP stabilization of a SESAM mode-locked Er:Yb:glass laser at 1.55 um with timing jitter below 3 as (1-3 MHz) and (2) a

The structuring of laser light with non-diffracting vector distributions, optical vortices, or high angular momentum are being increasing exploited. We present a system for the synthesis of these arbitrary intensity and phase profiles through a numbe

Hardware-based machine learning for photoinjector manipulation is a promising solution for real-time adaptive electron-beam manipulation. We present preliminary studies towards this goal including simulations of the optical system and early machine l
