Abstract:
A resonantly pumped Er:YAG vector laser emitting at 1645 nm with selective polarization states is demonstrated. A compact five-mirror resonator incorporated a pair of quarter-wave plates (QWPs), and a pair of q-plates (QPs) is employed. Cylindrical vector beams of all states on a single high-order Poincaré sphere could be obtained by rotating the QWPs and QPs relatively.
