GENERATION OF TWO COHERENT LASER SOURCES SELECTED FROM FEMTOSECOND LASER FREQUENCY COMB AND RESONANT TWO-PHOTON SPECTROSCOPY OF CESIUM ATOMS

摘要

We report on a generation of two coherent continuous wave (cw) laser sources with a wavelength difference of 57 nm based on a femtosecond laser frequency comb (FLFC) injection locked diode lasers. The FLFC wavelength near 852 nm is optically injected to the DBR diode laser, and the other DFB diode laser is injection locked by a FCFL at near 794 nm. Two diode lasers are independently injection locked by two different mode of one FLFC. Therefore, two diode lasers are phase-coherent because it is well known that individual mode of a FLFC are phase-coherent each other. We demonstrate the resonant two-photon spectroscopy of 6S{sub}(1/2)-6P{sub}(3/2)-8S{sub}(1/2) transition line for the Cesium atom by using two injection locked diode lasers.
