Lu, X. Wang, L. Miao, D. Zuo, Z. Cheng] Coherent terahertz radiation in a widely step-tunable range of 72.3-2706μm (0.11-4.15 THz) has been generated in GaAs crystal by difference-frequency generation using one CO2 laser with dual-wavelength output. The peak power of THz pulse reaches 35 W at the wavelength of 236.3μm, which corresponds to a pulse energy of 2.1μJ. An average power of 10μW has been achieved when working repetitively. This efficient terahertz radiation source is more compact and widely tunable than other THz sources pumped by CO2 laser. Springer-Verlag, 2010 Lu Y.
