| Research Abstract |
The continuous-wave-based multifrequency laser has been demonstrated through intracavity stimulated Raman scattering and four-wave mixing. Under a passively stabilized condition, the first Stokes, second Stokes and first anti-Stokes emission are generated. A intensity-modulated optical pulse train at a repetition rate of 17.6 THz is observed using an interferometric autocorrelator equipped with a high-sensitive nonlinear detector. In addition, a method proposed in this project allows us to measure a phase-slip between multifrequency emission lines quantitatively.
