"After more than 50 years since the invention of the laser, nonlinear optics has provided a viable solution to the generation of coherent light in arbitrary spectral regions from the UV to mid-IR. In the ultrafast regime, the exploitation of novel multistep nonlinear frequency conversion concepts based on parametric down-conversion and up-conversion of the Kerr-lens-mode-locked Ti:sapphire laser have overcome long-standing spectral barriers in the UV, visible, and IR, for the first time, providing gap-free wavelength coverage across an unprecedented range of 250-2500 nm from a single device, making new enabling tools available for cutting-edge applications."
