Abstract: Abstract We demonstrate a second-harmonic-generation frequency-resolved optical gating (SHG-FROG) apparatus, which can be used to accurately characterize ultrashort mid-infrared laser pulses. An initial guess with constraint both in time and frequency domain is first proposed… read more here.

DOI: 10.1109/jqe.2019.2950458
Abstract: We further improve and then demonstrate the reliability of the previously introduced RANA approach for the second-harmonic-generation frequency-resolved optical gating (SHG FROG) phase-retrieval algorithm in the presence of significant noise in the traces. We provide… read more here.

DOI: 10.1364/oe.27.001416
Abstract: We report a simple scheme for direct generation of frequency-bin entangled photon pairs via spontaneous parametric downconversion. Our fabricated nonlinear optical crystal with two different poling periods can simultaneously satisfy two different, spectrally symmetric nondegenerate… read more here.
