Phase-velocity measurement of a tightly focused Gaussian beam by use of sum frequency generation
Ke Wang, Liejia Qian, Ping Qiu, and Heyuan Zhu
In this letter, the nonuniform phase-velocity distribution of a tightly focused Gaussian beam is experimentally measured, both in the axial and the radial dimensions, through a nonlinear optical approach in a form of off-axis sum frequency generation. The experimental results demonstrate the superlu ... [Appl. Phys. Lett. 92, 121114 (2008)] published Fri Mar 28, 2008.
