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
