Large phase change by cascaded second-order effects in 3-methyl-4-methoxy-4′-nitrostilbene single crystals

Abstract

Although the χ(2)(ω;2ω, -ω):χ(2)(2ω;ω,ω) cascading process utilizes the second-order susceptibility, the nonlinear phase shift due to the process is exactly equivalent to that caused by the third-order susceptibility χ(3). Since the amount of phase change due to the second-order cascading effect is proportional to the square of the effective d-value, organic crystals with large second-order susceptibilities, such as 3-methyl-4-methoxy-4-nitrostilbene (MMONS), are of great interest in this respect. MMONS crystals show one of the largest second-order susceptibilities and the effective d-value was measured by Maker fringe technique to be deff = 38 pm/V at 1.064 μm.
