We present a new determination of the potential curves and interactions
of the coupled electronic states 
and 
of the potassium dimer,
based on new laser spectroscopy measurements within a molecular beam, combined with data
available in the literature. We used a new global deperturbation approach, involving
the Fourier Grid Hamiltonian method for energy level calculation. A standard deviation
of 1.2 is obtained corresponding to a variance of 
cm-1,
representing a significant improvement compared to the standard deviation of 4 yielded
by the traditional local deperturbation approach.
