Visible optical vortices measured with bulk lateral shearing interferometry
Miguel López-Ripa, Ãñigo Sola, BenjamÃn 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…
Analysis of phase instabilities in amplitude swing for ultrashort pulse train characterization
Cristian Barbero, Ãñigo J. Sola, BenjamÃn Alonso
The temporal dynamics of ultrashort pulses are a fundamental feature in ultrafast optics. These dynamics can often be extracted from a two-dimensional trace consisting of a set of…
Measuring ultrafast laser pulses using a single-shot amplitude swing implementation
Cristian Barbero, Ãñigo J. Sola, BenjamÃn 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)…
Ptychographic retrieval for complete ultrashort pulse amplitude swing reconstruction
Cristian Barbero, Ãñigo J. Sola, BenjamÃn Alonso
Ultrafast experiments require precise temporal characterization of laser pulses, where pulse reconstruction is typically achieved through iterative retrieval algorithms. In this co…
