Two-photon laser scanning fluorescence microscopy using photonic crystal fibre [PDF]

open access: yes, 2004
We report the application of a simple yet powerful modular pulse compression system, based on photonic crystal fibres which improves upon incumbent twophoton laser scanning fluorescence microscopy techniques.

Tunable single-cycle pulse compression at the group-velocity horizon

open access: yes, 2014
An adjustable adiabatic soliton compression scheme is presented, enabling pulse generation in the single-cycle regime. The compression comes without external dispersion compensation and is naturally stimulated by two-pulse collisions in an optical event ...

Three-wave mixing mediated femtosecond pulse compression in BBO [PDF]

open access: yes, 2015
Nonlinear pulse compression mediated by three-wave mixing is demonstrated for ultrashort Ti:sapphire pulses in a type II phase-matched β-barium borate (BBO) crystal using noncollinear geometry.

Advanced numerical studies of the neutralized drift compression of intense ion beam pulses

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2007
Longitudinal bunch compression of intense ion beams for warm dense matter and heavy ion fusion applications occurs by imposing an axial velocity tilt onto an ion beam across the acceleration gap of a linear induction accelerator, and subsequently ...
