我们展示了使用脉冲宽度约为 10 fs 的超短脉冲激光器，通过偶极型光电导天线对 0.1 至 100 THz 的太赫兹电场进行超宽带检测。超宽带太赫兹脉冲由薄 GaSe 晶体和低温生长的 GaAs 光电导天线产生。考察了光电导天线在中红外区域的灵敏度。
We demonstrate ultrabroadband detection of terahertz electric field from 0.1 up to 100 THz with a dipole-type photoconductive antenna using an ultrashort pulse laser whose pulse width is approximately 10 fs. Ultrabroadband terahertz pulses are generated with a thin GaSe crystal and a low-temperature grown GaAs photoconductive antenna. The sensitivity of the photoconductive antenna is examined in mid-infrared region.
