Product Introduction

efficiencyhighThe terahertz radiation source has a significant impact on a range of terahertz scientific and technological applications, with one important aspect being its wide bandwidth and high electric field strength. This usually relies on radiation sources with large excitation areas, which traditionally require high bias voltages (up to several hundred V) to excite and achieve THz electric field strengths of KV/cm. The large excitation area terahertz transmitter launched by Shanghai Yichi Optoelectronics is a high-efficiency photoconductive antenna with a large excitation surface and only requires a very low bias voltage.

technical specifications

The Tera SED launched by Shanghai Yichi Optoelectronics is a high-efficiency terahertz photoconductive antenna based on LT GaAs. We offer two different versions of large excitation area photoconductive antennas: the 10mm * 10mm excitation area antenna is suitable for amplifying femtosecond laser systems (single pulse energy can be as high as 300uJ); The 3mm * 3mm version of the photoconductive antenna is suitable for oscillating femtosecond lasers.
