Parametric light generation

Since its invention more than 40 years ago, the laser has become an indispensable
optical tool, capable of transforming light from its naturally incoherent state to
a highly coherent state in space and time. Yet, due to fundamental limitations,
operation of the laser remains confined to restricted spectral and temporal regions.
Nonlinear optics can overcome this limitation by allowing access to new spectral
and temporal regimes through the exploitation of suitable dielectric materials in
combination with the laser. In particular, optical parametric oscillators are versatile
coherent light sources with unique flexibility that can provide optical radiation across
an entire spectral range from the ultraviolet to the far-infrared and over all temporal
scales from continuous wave to the ultrafast femtosecond domain.
