摘要：
We present the first observation of two-color free-electron laser (FEL) operation using a single electron beam, single optical cavity, and a stepped undulator. The undulator is divided into two sections, each having different deflection parameters, K1 and K2, which set the resonance wavelengths for FEL oscillation at each of the nonharmonically related wavelengths. Each of the independently tunable optical pulses can have equal power, as high as half of that obtainable in single-wavelength FEL operation using both undulator sections. Presently the two-color FEL operates in the midinfrared spectral region.
