Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, narrowband terahertz (THz) radiation along with broadband terahertz has attracted great deal of attention in both fundamental and applied sciences. For many frequency specific applications, the tunability of both central frequency and bandwidth of the narrowband THz radiation is vital. In this paper, a narrow band high intense THz wave generation system that can be used for simultaneous measurement of waveform and pulse energy is demonstrated. This system can produce frequency and bandwidth tunable multi-cycle THz pulses by optical rectification of femtosecond laser pulses using periodically poled lithium niobate crystal (PPLN), shadow mask and phase mask. The central frequency can be tuned by varying period of the phase mask. The power of generated narrow band THz wave can be measured using a superconducting edge triggered bolometer.
