Abstract
It is shown that the nonlinearity in the response function of a holographic medium can lead to formation of gratings at the sum and difference frequencies of the exposing standing wave patterns. This nonlinear feature can be ultilized to create reflection holograms at spectral regions where the conventional techniques are not applicable. Specifically it is suggested that NIR or JR rejection filters which are sensorcentered can be obtained using this approach. 1.
