We demonstrate that diffractive lenses (DLs) can be used as a simple method to tune the central wavelength of
femtosecond pulses generated from second-order nonlinear optical processes in birefringent crystals. The wavelength
tunability is achieved by changing the relative distance between the nonlinear crystal and the DL, which
acts in a focusing configuration. Besides the many practical applications of the so-generated pulses, the proposed
method might be extended to other wavelength ranges by demonstrated similar effects on other nonlinear processes,
such as high-order harmonic generation.
