Description
Ultrafast light sources with a wavelength around two micrometers are
interesting for several experiments like high harmonic generation and
investigation of Brunel harmonics. We want to present a doubly
resonant optical parametric oscillator (DROPO) for intracavity experiments.
Our system is pumped by a home built kerr lens mode locked
Yb:YAG thin disk laser with a repetition rate of 34 MHz. The DROPO
is operating in a bowtie configuration and uses a BBO as the nonlinear
medium. The wavelength can be rapidly adjusted between the
degeneracy point up to 1900 nm + 2300 nm by cavity length tuning
alone. An additional focus point inside the cavity is suitable for an gallium
phophide wafer in which we want to excitate Brunel harmonics with the signal and
the pump wave.
