Propagation properties and M-2 factors of a vortex airy beam
We investigate the propagation properties and M-2 factor of a vortex Airy beam. The expression of M-2 factor as a function of the modulation parameters a(x) and a(y) is analytically obtained. The results indicate that the M-2 factor can achieve minimum M-2=2.33 when a(x)=a(y)=1.026 for the m= 1st or...
