We report high efficiency terahertz generation in DAST to investigate terahertz wave source with high power and tunability of polarization and frequency. DAST crystal was illuminated with linearly polarized light pulses. Generated terahertz pulses were reached 730 nJ with 230 \mu J pump. Pump dependence of generation efficiency and spectrum of the generated terahertz pulses will be discussed.
