Stimulated Raman radiation is considered in a ring optical resonator. It is supposed that the resonator is partly filled with a condensed medium at the full length of the medium close to several tunnel lengths. A Raman-active medium and an optical waveguide are assumed to occupy a part of the condensed medium. The feasibility is shown of tunnel generation and synchronization of a great number of Stokes components of stimulated Raman radiation. Here, femtosecond light pulses are shown to be formed in a spacing adjacent to the Raman-active medium, the pulses being single over the period T=2..pi../..omega.. /SUB R/ (..omega.. /SUB R/ is the Raman frequency shift). Predicted and considered also are tunnel generation and locking of new light modes in an optical parametric oscillator. The effects are due to a correction for the dispersion of the full effective refractive index of the medium inside the resonator. Numerical calculations of the correction for a glass thin-film optical waveguide, quartz, and the Raman-active media CaCO/sub 3/, C/sub 6/H/sub 6/, CS/sub 2/ inside the resonator are represented. Here, five or six Stokes components are shown to be generated and locked for CaCO/sub 3/ and C/sub 6/H/sub 6/, eight Stokes components for CS/sub 2/. A similar numerical calculation is represented for the active medium LiNbO/sub 3/ in the corresponding optical parameteric oscillator. Here, new modes covering a frequency bandwidth of 5000 cm/sup -1/ are shown to be feasible. Noted and discussed is also a higher-order correction for the effective refractive index dispersion making it feasible to broaden the frequency bandwidth for tunnel generation and locking.
