    "abstract": "We report on an attempt to generate highly stable continuous terahertz (THz)\nwave by using optical frequency comb (OFC). About 10-nm wide OFC has been\ngenerated through a deep phase modulation of a 852 nm laser line in lithium\nniobate crystal cavity. The multiple optical modes (side bands) of the OFC,\nwhich are equally separated from each other by the modulation frequency (=6\nGHz) are taken as the frequency reference. When another semiconductor laser is\nfrequency locked, the stability of the difference frequency between the master\nlaser and the second laser is improved on the same order of the RF modulator.\nAn ultra-narrow line and tunable THz radiation source can be achieved by\nphotomixing of this stable difference-frequency optical beat in a\nphotoconductive antenna.",
