.. [Clearly show full abstract] parametric oscillator. The two independently centered beams were produced to overlap Within the crystal. The concentrating parameters of the two beams were about the exact same. The focusing perform produced by Boyd and Kleinman for tightly focused beams was prolonged to periodically poled crystals so as to in good shape the temperature-tuning curve. A 0.66%/W efficiency was obtained for the main difference frequency mixing system.

We report on a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser because the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP 2 , synchronously pumped inside to your MgO:PPLN femtosecond OPO, We've got created broadly tunable radiation across 5958�?117 nm applying fast static cavity delay tuning, using a highest electrical power of 64 μW at 6791 nm, confined via the absorption in mirror substrates and also polarization-dependent intracavity losses.

A list of ~450 noncentrosymmetric sulfides has been noticed in reference to nonlinear optical Attributes. It has been identified that within the plane of your oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».

In both of those the cases acquired device mobile parameters are same, which displays the precision of existing strategy. The Digital band buildings demonstrate the semiconducting behavior in both equally the situations. The density of states plot also are studied and reviewed.

We report new experimental outcomes on the stage-matching Homes of yellow coloration HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-10.5910 μm array. Also, we current new Sellmeier equations that offer a fantastic replica with the current experimental final results along with the published data factors for second-harmonic technology of CO2 laser radiation at nine.

We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Together with signal and idler, it could be continuously tuned from one.261 as a result of two.532 μm by various the pump wavelength. Two big improvements were attained, including the connection in the signal and idler tuning ranges and also the high output pulse Power in the sign and idler tuning ... [Show complete abstract] ranges. The very first advancement was realized by exploring two certain sets of phase-matching angles. The 2nd enhancement was realized by making use of five sets of resonator mirrors for oscillating possibly sign or idler.

Taxonomy, chemical bonding relations and nonlinear optical Qualities of noncentrosymmetric sulfide crystals

Based on the theories of period matching and suitable composition ratio, the influence of composition ratio to the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, stage matching diagrams of next harmonic generation and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers have been calculated, as well as satisfactory composition ratios with various compositions.

Also, we carried out a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled that the spectral profile of the output from a CPOPO was appropriate to the two the parametric obtain profile of your nonlinear crystal along with the intra-cavity substantial-order dispersion.

... The main details over the refractive index of orange HGS posted by Levine et al. [35] involved only number of wavelengths while in the obvious and around-IR equally as an indication in the feasibility of the crystal for birefringent phase-matching. The refractive indices to the orange section ended up calculated and tabulated in between 0.

A pulsed TEA CO2 laser was applied to investigate the effect of pump radiation parameters (method structure, wavelength, and pulse period), focusing problems, absorption coefficient, and temperature about the efficiency of conversion into the next harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Very good agreement betweeen experimental and theoretical outcomes is noticed. Go through more

Diode-pumped optical parametric oscillation is demonstrated for the first time to our awareness in only one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take in the 812-nm radiation to crank out click here 1084-nm laser oscillation.
