In this Chapter, we present an overview of current and potential future developments in pulsed laser deposition of WOx for the realization of different nanostructures. Special focus is set on the mechanisms of PLD and RF-PLD for WOx thin films and, in addition, we try to show the potential of WOx thin films for different applications. In particular, we summarize the potential of WOx thin films in gas sensor applications, electrochromic devices, solar cells, field emission applications, and finally, we present a few biological applications.
