and running conditions for the sensible design and style of superior electrical power femtosecond optical parametric oscillators with excitation
Output idler energies over the microjoule amount are received with optimum conversion effectiveness of 11% to the amplifier phase, which happens to be a lot more than two periods better than the final results obtained by having an analogous sample with the commonly distribute material AgGaS two .

.. [Exhibit whole abstract] third-harmonic generation and parametric amplification with small-frequency pumping in periodically poled active nonlinear crystals will also be investigated. The Evaluation is performed for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of making use of periodically poled Lively nonlinear crystals in laser equipment with self-frequency conversion are mentioned.
We report new experimental final results on the stage-matching Houses of yellow color HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm vary. Furthermore, we existing new Sellmeier equations that offer a great copy of the present experimental benefits as well as the published info points for 2nd-harmonic technology of CO2 laser radiation at 9.
The calculated core level binding energies are when compared with Those people of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being independent about the technological situations of crystal development. In contrast to the valence band spectrum, the distribution of electron states during the bandgap of HgGa2S4 crystals is located to generally be strongly dependent upon the technological conditions of crystal progress as shown by the photoluminescence Assessment.
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are analyzed working with perturbation idea underneath the ailment of rotating wave approximation. The 2 parametric FWM processes are coupled when they're psyched coherently by a brief laser pulse which has a bandwidth encompassing The 2 corresponding upper Vitality degrees in The 2 FWM processes.
A technique is produced to unravel the procedure of shortened equations describing parametric technology inside of a one particular-frequency OPO cavity below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals and also the exceptional reflection coefficient in the output mirror are believed compared to the pump Electricity density Wp at various values with the OPO nonstationarity .

Interference is observed concerning the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
The noticed f -to- 2 file frequency beats, originating directly from the OPO, can be employed for self-referencing and period locking from the pump laser comb without get more info having for supercontinuum era. With an average output electric power of �?30 mW , this set up may very well be advantageous for several different spectroscopic apps within the mid-IR.
Mid-IR next-buy NLO crystal is indispensable within the frequency conversion programs within the mid-IR region. In contrast with DUV and UV/Vis/around-IR NLO crystals, useful mid-IR NLO crystals are reasonably unusual, and plenty of of them are still in the phase of laboratory investigate. This chapter assessments the the latest development about the mid-IR NLO crystals, which largely contains developing the classical mid-IR NLO crystals into big high-quality kinds or into quasi-stage-matching structures which have been appropriate for the laser products by many growth procedures and exploring new likely mid-IR NLO crystals by introducing new structure and synthesis strategies.
Distinction frequency mixing of strongly focused Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been focused inside the crystal without damage. Mixing of cw and pulsed laser systems was employed to attenuate the thermal lensing results within this crystal. A minimal-electrical power cw 1.064‐μm Nd:YAG laser beam was used as the pump, Whilst the sign beam came from a picosecond optical .
