Observation of Anomalous Orbital Angular Momentum Conservation in Parametric Nonlinearity
Hai-Jun Wu, Bing-Shi Yu, Jia-Qi Jiang +5
Orbital angular momentum (OAM) conservation plays an important role in shaping and controlling structured light with nonlinear optics. The OAM of a beam originating from three-wave…

Directly determining orbital angular momentum of ultrashort Laguerre-Gauss pulses via autocorrelation measurement
Bing-Shi Yu, Chun-Yu Li, Yuanjie Yang +2
Autocorrelation measurement based on second-harmonic generation (SHG), the best-known technique for measuring the temporal duration of ultrashort pulses, could date back to the bir…
