  • Apurv Chaitanya, N.; Jabir, M. V.; Samanta, Goutam Kumar (Springer, 2016-04)
    We report on efficient nonlinear generation of ultrafast, higher order "perfect" vortices at the green wavelength. Based on Fourier transformation of the higher order Bessel-Gauss (BG) beam generated through the combination ...
  • Apurv Chaitanya, N.; Chaitanya Kumar, S.; Aadhi, A.; Samanta, Goutam Kumar; Ebrahim-Zadeh, M. (Nature Publishing Group, 2016-08)
    We report on the first realization of an ultrafast Airy beam optical parametric oscillator (OPO). By introducing intracavity cubic phase modulation to the resonant Gaussian signal in a synchronously-pumped singly-resonant ...
