THz Emission Driven by a Dual-Transverse-Modes Laser

The state of the art and the perspectives of THz emission driven by a dual-frequency laser that operates simultaneously on two transverse modes around 1064 nm are presented. The reported THz performances in terms of tunability (50-700-GHz), coherence (150-kHz for 3-ms acquisition time), and power (1...

Summary:The state of the art and the perspectives of THz emission driven by a dual-frequency laser that operates simultaneously on two transverse modes around 1064 nm are presented. The reported THz performances in terms of tunability (50-700-GHz), coherence (150-kHz for 3-ms acquisition time), and power (1\ \mu\text{W} at 260 GHz) are presented while using a uni-travelling-carrier photodiode for photo-mixing. Novel photo-mixers specifically designed to match the transverse modes of the laser are discussed in terms of transverse beam characteristics and power.
