Simultaneous generation of high power, ultrafast 1D and 2D Airy beams and their frequency doubling characteristics
Raghwinder S. Grewal, Anirban Ghosh, G. K. Samanta
We report on a simple experimental scheme based on a pair of cylindrical lenses (convex and concave) of same focal length and common optical elements producing high power optical b…
High-power, continuous-wave, tunable mid-IR, higher-order vortex beam optical parametric oscillator
A. Aadhi, Varun Sharma, G. K. Samanta
We report on a novel experimental scheme to generate continuous-wave (cw), high power, and higher-order optical vortices tunable across mid-IR wavelength range. Using cw, two-cryst…
Controlled generation, manipulation and frequency conversion of broadband orbital angular momentum spectrum of asymmetric optical vortex beams
Sabir Ul Alam, A. Srinivasa Rao, Anirban Ghosh +2
We report on generation and control of tunable, broad orbital angular momentum (OAM) spectrum of a vortex beam. Using two spiral phase plates (SPPs), we have converted the Gaussian…
