采用1040 nm，80 fs，180 mW，48 MHz的锁模光纤激光器，在2 T的磁场中，通过小型永磁体，从InAs中产生热接收器可探测的太赫兹辐射。太赫兹辐射监测的氘代三甘氨酸硫酸盐（DTGS）热释电热接收器的装置。DTGS在室温下工作，不需要时间门控调整或用液氦冷却制冷剂。太赫兹辐射发射器系统，包括激发激光头，几乎与传统的笔记本电脑相同的大小。
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.
