✦ Synopsis

In this letter we present an approach to CARS microscopy, which compromises between fast acquisition rates and the amount of chemical information obtained. By using a light modulator as tunable filter in concert with narrowband pump and broadband Stokes pulses, we demonstrate an experimental arrangement, which allows for fast electronic switching between CARS images recorded at different Raman resonances without the need for any optical adjustment.

## Abstract This article proposes the design of tunable dual‐band filters for multiband multistandard systems, specifically for wireless local‐area network applications. The two main goals are to provide frequency tunability in the second band while maintaining the first band fixed and to obtain a
