The frequency range and output power of THz-wave generated from GaSe crystals were investigated from the viewpoint of carrier density. THz-waves were generated from the low carrier density GaSe (1010 cm-3) in a wider frequency range than that from the high carrier density GaSe (10 14 cm-3). At frequency below 1.3 THz, the THz-wave output power increases with decreasing carrier density in GaSe. By using GaSe with lower carrier density, higher power and a wider frequency range of the THz-wave generation would be expected.
