Abstract
Two-frequency solid-state lasers are shown to provide beat notes at frequencies from dc to the THz range with continuous tunability, high spectral purity and 100% modulation depth. Depending on the desired range, one- and two-axis cavities are built. Applications of such lasers as a local oscillator in radio-over-fibre communication systems or as a tunable highly coherent THz source are emphasized.
