Abstract

We have demonstrated a compact and portable terahertz (THz) source, based on difference-frequency generation in a GaSe crystal. The two input frequencies, required for achieving frequency mixing, are generated by a single Q-switched Nd:YLF laser incorporating two laser resonators. The average power of the THz output reaches 1μW at 1.64THz (182μm) within a linewidth of 65GHz. Such a THz source can be packaged into a compact and portable system.
