    • Generation of pulse trains with nonconventional temporal correlation properties 

      Talukder, Ria; Halder, Atri; Koivurova, Matias; Ding, Chaoliang; Setälä, Tero; Turunen, Jari; Friberg, Ari T
      We apply time dependent spectral phase modulation to generate pulse trains that are spectrally and temporally partially coherent in an ensemble averaged sense. We consider, in particular, quadratic spectral phase modulation ...

    • Partially coherent isodiffracting pulsed beams 

      Koivurova, Matias; Ding, Chaoliang; Turunen, Jari; Liuzhan, Pan (American Physical Society (APS), 2018)
      We investigate a class of isodiffracting pulsed beams, which are superpositions of transverse modes supported by spherical-mirror laser resonators. By employing modal weights that, for stationary light, produce a Gaussian ...

    • Spectral invariance and scaling law for nonstationary optical fields 

      Ding, Chaoliang; Koivurova, Matias; Setälä, Tero; Turunen, Jari; Friberg, Ari T (American Physical Society (APS), 2020)
      We develop a scaling law for a class of statistically nonstationary scalar optical fields, which ensures spectral invariance on their propagation into the far zone of a planar source. The invariance involves the constraint ...

    • Temporal self-splitting of optical pulses 

      Ding, Chaoliang; Koivurova, Matias; Turunen, Jari; Pan, Liuzhan (American Physical Society (APS), 2018)
      We present mathematical models for temporally and spectrally partially coherent pulse trains with Laguerre-Gaussian and Hermite-Gaussian Schell-model statistics as extensions of the standard Gaussian Schell model for pulse ...
