Generation of Highly Repetitive Optical Pulses Based on Intracavity Four-Wave Raman Mixing

Abstract

An extremely long train of highly repetitive pulse (17 THz) is obtained by the rotational four-wave Raman mixing of molecular hydrogen in a resonator using a computer simulation. This highly repetitive pulse can be obtained only when the laser wavelength and the resonator are adjusted to specified values. This pulse train has potential for use in ultrafast data communication because of the accurately determined repetition rate or even as a frequency standard, since the frequencies of the emission lines can be stabilized and locked to the above values.
