Data for Radially- and azimuthally- polarized nanosecond Yb-doped MOPA system incoporating temporal shaping
Abstract: We report an Yb-doped fiber master-oscillator power-amplifier (MOPA) system with the capability of selectively generating doughnut-shaped radially- and azimuthally-polarized beams with user-defined temporal pulse shapes. The desired output polarization was generated with the aid of a nanograting spatially variant half-waveplate (S-waveplate). The latter was used to convert the linearly-polarized fundamental (LP01) mode output from the pre-amplification stages to a doughnut-shaped radially-polarized beam prior to the power amplifier stage. A maximum output pulse energy of ~860 µJ was achieved for ~100 nanosecond pulses at 25 kHz with user defined pulse shape for both radial and azimuthal polarization states. The polarization purity and beam propagation factor (M2) were measured to be >12dB and 2.2 respectively.The data relates to the paper: Lin, Di, Baktash, Neda and Berendt, Martin et al. (2017) Radially- and azimuthally- polarized nanosecond Yb-doped MOPA system incoporating temporal shaping. (doi:10.1364/OL.99.099999).
