Tunable narrowband THz waveforms were generated from laser induced gas plasma using shaped optical pulses. Square wave phase patterns were fed to a spatial light modulator. The frequency and amplitude of the square wave phase were used as parameters to tailor the terahertz waveforms. The dependence of THz waveforms on these parameters has been studied in detail. The presence of the ionization thresholds for pulse shaping is also discussed. We have demonstrated the wide and continuous tunability of the central frequency of the narrowband THz waveform from 2.5 to 7.5THz.
