WANTED: a narrowband THz source for spectroscopy Problem Solution Requirements • Want to do frequency domain spectroscopy at THz frequencies • No existing narrowband source provides good power in THz range • Short pulse sources - good for time-domain spectroscopy * CW - good for imaging if you have enough power • Want a source which will produce – 300-1000 micron radiation (0.3-1 THz) – ~1 Watt peak power – ~5 nanosecond pulses – Narrowband
