| Popis: | Thermal receiver detectable terahertz (THz) radiation is generated from InAs irradiated with a 1040 nm, 80 fs, 180 mW, 48-MHz-repetition-rate mode-locked fiber laser in a 2 T field by a compact permanent magnet. THz radiation is monitored by means of a deuterated triglycine sulfate (DTGS) pyroelectric thermal receiver. DTGS operates at room temperature and does not require time-gating adjustment or cryogen cooling with liquid helium. The THz-radiation emitter system, including the excitation laser head, is almost the same size as a conventional notebook computer. |
