چکیده
We demonstrate generation and frequency doubling of unit charge vortices in a linear astigmatic resonator. Topological instability of the double charge harmonic vortices leads to well separated vortex cores that are shown to rotate, and become anisotropic, as the resonator is tuned across resonance.

متن کاملSimultaneous optical parametric oscillation and intracavity second-harmonic generation based on a hexagonally poled lithium tantalate.
Simultaneous optical parametric oscillation and intracavity second-harmonic generation based on a hexagonally poled lithium tantalate is reported. Both the optical parametric oscillation and the cascaded noncollinear second-order harmonic generation processes reach a high efficiency. A variety of possible self-doubling optical parametric oscillation processes indicate this hexagonally poled lit...
متن کاملArbitrary orbital angular momentum addition in second harmonic generation
We demonstrate second harmonic generation performed with optical vortices with different topological charges imprinted on orthogonal polarizations. Besides the intuitive charge doubling, we implement arbitrary topological charge addition on the second harmonic field using polarization as an auxiliary parameter.
متن کاملDynamics of a paired optical vortex generated by second-harmonic generation.
We study the dynamics of a paired optical vortex (OV) generated by second-harmonic generation (SHG) using sub-picosecond pulses. By changing the position of a thin nonlinear crystal along the propagation direction, we observe a rotation of two vortices with changing separation distance. The dynamics is well explained by SHG with a beam walk-off, which introduces a contamination of zero-order La...
متن کاملMode locking by a frequency-doubling crystal: generation of transform-limited ultrashort light pulses.
Transform-limited ultrashort green and infrared light pulses have been generated from a Nd:YAG laser mode locked by an intracavity second-harmonic crystal in combination with a dichroic output coupler. The mode-locking process is based on substantial reconversion of the second-harmonic radiation back into fundamental radiation after reflection by the dichroic mirror. With this technique light p...
