and working circumstances for the sensible design and style of higher electric power femtosecond optical parametric oscillators with excitation
Output idler energies on the microjoule stage are obtained with maximum conversion efficiency of 11% for the amplifier stage, which is greater than two times a lot better than the final results received by having an analogous sample of the greatly distribute content AgGaS 2 .
The 1st-ideas density useful calculations are performed to study the geometries and electronic buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, and the optical Qualities of all crystals are investigated systematically. The results suggest that these compounds have very similar band buildings as well as band gap decreases from S to Se to Te. For that linear optical properties, three crystals present very good light-weight transmission in the IR and element noticeable regions, and in particular, HgGa2S4 and HgGa2Se4 crystals possess reasonable birefringence.
A straightforward technique for decreasing the loss that is because of depolarization ensuing from thermally induced worry birefringence in solid-state lasers is reported. The method utilizes just one intracavity quarter-wave plate with its quickly or sluggish axis aligned parallel to the popular plane of polarization, defined by an intracavity polarizer.
We report new experimental effects around the period-matching Homes of yellow shade HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm variety. Additionally, we present new Sellmeier equations that offer a very good copy with the existing experimental final results along with the revealed facts points for 2nd-harmonic generation of CO2 laser radiation at nine.
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it may be consistently tuned from 1.261 by way of two.532 μm by different the pump wavelength. Two main enhancements have been obtained, including the connection of your sign and idler tuning ranges as well as the substantial output pulse Strength from the sign and idler tuning ... [Exhibit total abstract] ranges. The primary improvement was achieved by finding two individual sets of period-matching angles. The next advancement was understood by making use of 5 sets of resonator mirrors for oscillating both sign or idler.
Taxonomy, chemical bonding relations and nonlinear optical Qualities of noncentrosymmetric sulfide crystals
We current a numerical review for the look of effective MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top rated-hat click here transverse depth profile, along with a double-move pump cavity configuration. In particular, we examine the result of area shape to the conversion performance. We considered two sorts of domain constructions: "best vertical-wall" and "wedge-shaped" domains and our numerical results display that at increased pump pulse energies, the conversion performance saturates, plus the saturated efficiency is sort of unbiased from the area shapes.
Furthermore, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled which the spectral profile of the output from a CPOPO was pertinent to both the parametric acquire profile from the nonlinear crystal and also the intra-cavity significant-purchase dispersion.
Topics may be refined further in the search results. The subject facet will expose the higher-stage topics affiliated with the content articles returned during the search results. SPECIAL COLLECTIONS
... The first info on the refractive index of orange HGS published by Levine et al. [35] involved only several wavelengths during the visible and in the vicinity of-IR equally as a demonstration with the feasibility of the crystal for birefringent period-matching. The refractive indices to the orange stage were measured and tabulated amongst 0.
to the detection of molecular trace gasses. The oscillation threshold, output power and stability of the single resonant
Current mid-IR NLO crystals can be divided into four types, i.e., classical binary and ternary metal pnictides and chalcogenides, quaternary metal chalcogenides, binary and ternary metal halides, and various-bond-kind hybrid compounds that have at the least two types of clearly distinct chemical bonds in the crystal constructions. Metallic pnictides and chalcogenides have bought Considerably focus on developing huge crystals. Various-bond-style hybrid is a different household of mid-IR NLO materials, and plenty of of these were being found in the final ten years. In metallic halide system, each progress in expanding substantial crystals and identifying new kinds have been produced.
Tunable mid-IR radiation is obtained during 2nd harmonic generation of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning properties at the CO2- laser wavelength, angular acceptance angle and spectral acceptance are calculated.
