Abstract

We experimentally generate optical vortices in the output beam of Ti:Sapphire laser emitting 20-fs pulses. Screw phase dislocations are imposed in each spectral component of the short pulses by aligning computer-generated hologram within a 4f-setup.

飞秒激光场中的涡流

实验中，我们在发射20fs脉冲的钛蓝宝石激光器的输出光束中产生了光学涡流。螺旋位错施加于短脉冲的每个光谱分量通过对准计算机生成的全息图在4f设置。
