Summary from only given. We successfully demonstrate widely tunable and high frequency THz-wave generation in the range of 1.5 to 6.5 THz with thin DAST crystals for the first time. We show an arrangement for THz-wave generation in DAST by mixing dual wavelengths of KTiOPO/sub 4/ optical parametric oscillator which has two KTP crystals in the same cavity.
