Optical parametric generation in periodically poled KTiOPO4 via extended phase matching

We report an experimental demonstration of optical parametric generation in a periodically poled KTiOPO4 crystal based on the principle of mirrorless optical parametric oscillation. A femtosecond pump pulse spectrally centered at 792 nm from a Ti:sapphire amplifier is prechirped to minimize Kerr effects. The pump pulse is then injected into the nonlinear crystal and down converted to signal and...

Optical Parametric Amplification with Periodically Poled KTiOPO4

This thesis explores the use of engineered nonlinear crystals from the KTiOPO4 (KTP) family as the gain material in optical parametric amplifiers (OPAs), with the aim to achieve more knowledge about the benefits and limitations of these devices. The work aims further at extending the possible applications of OPAs by constructing and investigating several efficient and well performing amplifiers...

Extended phase matching of second-harmonic generation in periodically-poled KTiOPO4 with zero group-velocity mismatch

Under extended phase-matching conditions, the first frequency-derivative of the phase-matching function is zero and the phase-matching bandwidth is greatly increased. We made extensive three-wave mixing measurements to identify the operating point for extended phase matching, thus permitting us to observe a type-II phase-matching bandwidth of 100 nm centered at the fundamental wavelength of 158...

Generation of tunable green radiation in bulk periodically poled KTiOPO4

We report a characterisation of a flux-grown periodically poled KTiOPO4 crystal used for second-harmonic generation in a diode laser source, that operates with fundamental radiation tunable around 1083 nm wavelength. The conversion efficiency is measured for the three different grating periods of the crystal, as a function of input wavelength, crystal temperature and fundamental power. The meas...

Ultra-broadband optical parametric generation in periodically poled stoichiometric LiTaO3.

We report on broadband gain in an optical parametric generator based on periodically poled 1 mol% magnesium-doped stoichiometric LiTaO3 (PPMg:SLT). More than an octave-spanning parametric gain, stretching from near to mid-infrared, is generated by pumping the crystals close to the point where, at parametric degeneracy, the waves experience zero group-velocity dispersion. Using a picosecond Ti:s...
