Vortex laser generation with controllable topological charges in a spiral phase defect resonator (JTu1A.9)
Presenter: YuanYao Lin, National Sun Yat-Sen University
We propose an optical cavity with spiral phase defect for vortex laser generation. Utilizing a reflective spatial light modulator that creates variable spiral phase defect, vortex beams with controllable topological charges are demonstrated.
