Thermal Receiver Detectable THz Radiation from an InAs Irradiated With 1.04-Micrometers Femtosecond Fiber Laser in a 2-T Permanent Magnet

Abstract

Thermal receiver detectable THz radiation is generated from an InAs irradiated with 1.04 micrometer, 80-fs, 180mW fiber laser in a 2-T field by a compact permanent magnet. The THz radiation is monitored by a pyroelectric thermal receiver that is Deuterated Triglycine Sulfate (DTGS). DTGS operates at room temperature and it neither require time-gating adjustment nor cryogen cooling operation using liquid helium. The size of THz-radiation emitter system becomes almost the same as the conventional notebook computer size including the excitation laser head.
