Measuring ultrafast laser pulses using a single-shot amplitude swing implementation
Cristian Barbero, Íñigo J. Sola, Benjamín Alonso
Single-shot characterization techniques are crucial when dealing with shot-to-shot pulse-shape fluctuations (e.g., unstable laser systems, high-power, or with low repetition rate)…
Visible optical vortices measured with bulk lateral shearing interferometry
Miguel López-Ripa, Íñigo Sola, Benjamín Alonso
Ultrafast pulse optical vortices are spatiotemporal structures with a diverse range of applications. There are different ways to generate them, often restricted to a wavelength ran…
Ptychographic retrieval for complete ultrashort pulse amplitude swing reconstruction
Cristian Barbero, Íñigo J. Sola, Benjamín Alonso
Ultrafast experiments require precise temporal characterization of laser pulses, where pulse reconstruction is typically achieved through iterative retrieval algorithms. In this co…
Sparse Reconstruction of Wavefronts using an Over-Complete Phase Dictionary
S. Howard, N. Weisse, J. Schroeder +5
Wavefront reconstruction is a critical component in various optical systems, including adaptive optics, interferometry, and phase contrast imaging. Traditional reconstruction metho…
