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...
متن کاملGeneration 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...
متن کاملBroadband amplitude squeezing in a periodically poled KTiOPO4 waveguide.
We generated -2.2 dB of broadband amplitude squeezing at 1064 nm in a periodically poled KTiOPO4 (PPKTP) waveguide by coupling of the fundamental and second-harmonic cw fields. This is the largest amount of squeezing obtained to date in a KTP waveguide, limited by propagation losses. This result paves the way for further improvements by use of lower-loss buried ion-exchanged waveguides.
متن کاملTunable midinfrared source by difference frequency generation in bulk periodically poled KTiOPO4
We demonstrate quasi-phase-matched difference frequency generation in periodically poled KTiOPO4. A midinfrared ~3.2–3.4 mm! idler with a power level of 0.17 mW is generated by mixing a Nd:YAG laser and tunable external cavity laser near 1550 nm which is amplified by an erbium-doped fiber amplifier. The wavelength, temperature, and angle tuning characteristics of this device are determined. The...
متن کاملHigh-flux source of polarization-entangled photons from a periodically-poled KTiOPO4 parametric downconverter
We have demonstrated a high-flux source of polarization-entangled photons using a type-II phasematched periodically-poled KTiOPO4 parametric downconverter in a collinearly propagating configuration. We have observed quantum interference between the single-beam downconverted photons with a visibility of 99% together with a measured coincidence flux of 300/s per mW of pump. The Clauser-Horne-Shim...
