Abstract :
Summary form only given.Intense rapidly tunable picosecond laser pulses have been generated in the far-infrared from 30 to 250 /spl mu/m, a range that is not well covered by other sources. The transform-limited, diffraction-limited laser pulses have energies of up to 17 /spl mu/J, peak powers of more than 1 MW, a length of only 18 periods of the optical field, and focused intensities of 0.1 GW/cm/sup 2/. The far-infrared free-electron laser opens up the exciting possibility of performing nonlinear experiments in a relatively unexplored spectral range.
