Optical parametric oscillator pumped at ~one µm with intracavity mid-IR big difference-frequency era in OPGaAs
It has extended been predicted which the period difference between the sign and idler subharmonic outputs of an optical parametric oscillator (OPO) undergoes a random wander approach, just like the period diffusion of a laser [one].
The primary-rules density useful calculations are executed to check the geometries and Digital buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite buildings, and also the optical Houses of all crystals are investigated systematically. The outcome suggest that these compounds have identical band constructions and also the band gap decreases from S to Se to Te. For the linear optical properties, 3 crystals demonstrate very good gentle transmission from the IR and aspect noticeable areas, and especially, HgGa2S4 and HgGa2Se4 crystals have average birefringence.
In both equally the instances received unit mobile parameters are very same, which reveals the precision of current strategy. The Digital band constructions present the semiconducting behavior in each the situations. The density of states plot can also be studied and discussed.
We report new experimental results on the stage-matching Qualities of yellow coloration HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-ten.5910 μm array. In addition, we existing new Sellmeier equations that give a superior reproduction in the existing experimental final results plus the posted knowledge points for 2nd-harmonic generation of CO2 laser radiation at nine.
PA Ref-cell, which appreciably cuts down themeasurement faults with the methane concentration in thecase of instability
Taxonomy, chemical bonding relations and nonlinear optical Houses of noncentrosymmetric sulfide crystals
We current a numerical review for the look of successful MgO:PPLN based mostly pulsed click here nanosecond optical parametric oscillator (OPO), with enter pump pulses of leading-hat transverse depth profile, as well as a double-pass pump cavity configuration. In particular, we investigate the influence of domain shape to the conversion efficiency. We considered two types of domain structures: "ideal vertical-wall" and "wedge-formed" domains and our numerical final results display that at bigger pump pulse energies, the conversion efficiency saturates, plus the saturated effectiveness is almost unbiased of your area shapes.
Modeling and experimental review on period matching of second harmonic era in several color Hg Ga 2 S four crystals are completed. Using the regarded Sellmeier equations, the dispersion relation with weighting proportionally to quick-wavelength boundary from the crystal transparency band is proposed.
This paper evaluations the current developments in crystal progress and singly resonant optical parametric oscillators with the era of large single pulse Strength and normal powers while in the mid-IR from 3 to 10 μm.
... The 1st knowledge over the refractive index of orange HGS revealed by Levine et al. [35] provided only several wavelengths from the noticeable and close to-IR just as an illustration with the feasibility of this crystal for birefringent phase-matching. The refractive indices to the orange stage have been measured and tabulated amongst 0.
Quantum mechanical dependent to start with basic principle calculations are used to acquire the unit cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for The very first time. For this, we handled HgGa2S4 in two differing types of internet site symmetries in the same space team.
Current mid-IR NLO crystals is often divided into four groups, i.e., classical binary and ternary metallic pnictides and chalcogenides, quaternary metal chalcogenides, binary and ternary steel halides, and distinctive-bond-variety hybrid compounds that contain at the least two different types of obviously diverse chemical bonds from the crystal structures. Steel pnictides and chalcogenides have got Significantly interest on developing substantial crystals. Unique-bond-style hybrid is a whole new family members of mid-IR NLO elements, and many of these have been located in the last decade. In metallic halide process, each progress in increasing massive crystals and exploring new kinds have been produced.
Tunable mid-IR radiation is received all through next harmonic technology of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning attributes within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are calculated.
