[ALPS8-01(Invited)] Single crystal fibers for direct amplification of femtosecond optical vortices

*Yongguang Zhao¹ (1. Jiangsu Normal University)

We exploit a straightforward approach to directly amplify a femtosecond optical vortex by using a single-crystal fiber amplifier system, the spatial and temporal features can be well-conserved during the amplification
