Abstract
Shapiro steps by NbN thin-film Josephson junctions (JJ) have been recently observed at above 1THz1. Frequency mixing around 1THz may be hopefully achieved with these types of JJ's.

However, it is necessary to obtain FIR coherent sources with appropriate performance for these experiments. We should also count large power loss in quasi-optical components usually used in the submillimeter region: this demands a rather high power source (20∼30mW, > 500 ∼ 600GHz). Candidate sources for this purpose are optically pumped and discharge pumped FIR gas lasers. We have developed a high-power optically pumped FIR laser modifying an Apollo 125 model and examined its characteristics. The laser will be used as a calibration source for FIR spectroscopy and for testing submillimeter detectors and mixers, too.
