Generalized spectral phase-only time-domain ptychographic phase reconstruction applied in nonlinear microscopy
George Dwapanyin, Dirk Spangenberg, Alexander Heidt +4
Nonlinear microscopy has evolved over the last few decades to become a powerful tool for imaging and spectroscopic applications in biological sciences. In this study, IPIE, a n…
Implementation of temporal ptychography algorithm, IPIE, for improved single-beam coherent anti-Stokes Raman scattering measurements
Ruan Viljoen, Pieter Neethling, Dirk Spangenberg +4
We present an improvement on the signal-to-background of single-beam coherent anti-Stokes Raman scattering (SB-CARS) spectroscopy measurements for systems employing ultrafast super…
Low noise all-fiber amplification of a coherent supercontinuum at 2 μm and its limits imposed by polarization noise
Alexander M. Heidt, Joanna Modupeh Hodasi, Anupamaa Rampur +4
We report the amplification of an all-normal dispersion supercontinuum pulse in a Thulium / Holmium co-doped all-fiber chirped pulse amplification system. With a -20 dB bandwidth o…
Measurement of complex supercontinuum light pulses using time domain ptychography
Alexander M. Heidt, Dirk-Mathys Spangenberg, Michael Brügmann +2
We demonstrate that time-domain ptychography, a recently introduced ultrafast pulse reconstruction modality, has properties ideally suited for the temporal characterization of comp…
