We have developed the Febry-Perot type contact grating device for intense THz generation. In this device, the grating to tilt the pulse front of the pump pulse is contacted on the LiNbO₃ crystal. To realize the contact grating device, we employed the Febry-Perot cavity on the LiNbO₃ crystal to obtain the high diffraction ratio of the grating. In this paper, we introduce the characteristic of the device, and discuss the intrinsic problems and its solutions.
