053 μm. The absorption spectrum of ammonia was offered to reveal the feasibility of the designed optical parametric oscillator system for spectroscopic measurements and gasoline detection.
Output idler energies to the microjoule amount are acquired with most conversion effectiveness of eleven% with the amplifier stage, that's in excess of two situations much better than the effects attained having an analogous sample with the extensively unfold material AgGaS 2 .

.. [Present complete summary] third-harmonic generation and parametric amplification with reduced-frequency pumping in periodically poled active nonlinear crystals also are investigated. The Assessment is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of applying periodically poled active nonlinear crystals in laser units with self-frequency conversion are talked about.
In this get the job done, we existing what exactly is, to our know-how, the initial measurements with the quantum period diffusion sound of the cw OPO. Study additional
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Such as signal and idler, it could be repeatedly tuned from one.261 by way of 2.532 μm by various the pump wavelength. Two big enhancements have been reached, such as the connection of the sign and idler tuning ranges and the higher output pulse energy through the sign and idler tuning ... [Clearly show complete abstract] ranges. The initial enhancement was achieved by exploring two individual sets of period-matching angles. The 2nd enhancement was understood by making use of 5 sets of resonator mirrors for oscillating possibly signal or idler.
Two parametric four-wave-mixing (FWM) processes in Rb atoms are analyzed applying perturbation idea under the issue of rotating wave approximation. The 2 parametric FWM procedures are coupled when they're energized coherently by a brief laser pulse that has a bandwidth encompassing The 2 corresponding upper Power concentrations in The 2 FWM procedures.
air hole and enthusiastic in sequence by a standard pump beam. The stage in the interference is determined by the phase shifts at three frequencies.
The specific warmth and thermal conductivity of HgGa2S4 are measured. It's concluded the mixed properties of HgGa2S4 crystals can provide for them a number one position One of the materials used in nonlinear-optical gadgets for mid-IR-frequency conversion.

The approach is predicated on group velocity matching among interacting waves As well as birefringent period matching. We will describe broadband SHG attributes with regards to beam propagation directions, spectral positions of resonance, productive nonlinearities, spatial wander-offs concerning interacting beams, and spectral bandwidths. The final results will exhibit the spectral bandwidths of the basic wave allowed for broadband SHG to achieve numerous hundreds of nm. The corresponding SH spectral array spans from 1758.58 to 4737.eighteen nm from the non-oxide crystals regarded as In this particular research. Such broadband SHG making use of limited pulse trains can likely be placed on frequency up-conversion imaging during the mid-IR location, in info transmission, As well as in nonlinear optical signal processing.
The noticed f -to- 2 file frequency beats, originating straight from the OPO, may be used for self-referencing and stage locking in the pump laser comb without having for supercontinuum generation. With a mean output energy of �?30 mW , this set up is likely to be beneficial for many different spectroscopic applications inside the mid-IR.
Within this paper we theoretically look into the most successful pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Evaluation includes solving the best Management trouble utilizing the amount equation formalism. The OPO exceptional buildup habits is derived for any OPO configuration, and we clearly show which the optimum pump pulse condition is really a double read more rectangle. The first rectangle is optimized for that buildup method, though the next one particular is optimized to the continuous condition, and equally depend in another way on the OPO mirror reflectivities along with the readily available pump Electrical power and highest peak ability.
