Abstract
A spin-flip Raman laser is fed simultaneously with two or more output frequencies of the CO pump laser. Not only are resonance effects seen when the magnetic field is tuned so that the Raman frequency equals the difference of two pump frequencies, but also when higher order resonances involving the sums and differences of CO lines equal the Raman frequency. The sign and intensity of these effects are briefly discussed and it is pointed out that the effects could be useful for calibration purposes.
