Solid-State Laser Engineering is published from an industrialperspective and discusses intimately the characteristics, style and design, building and practical complications of reliable-statelasers. Emphasis is placed on engineering and practicalconsiderations, that has a phenomenological treatment method usingmodelsbeing chosen to abstract mathematical derivations.

We report on the femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) dependant on the Kerr-lens-mode-locked Ti:sapphire laser because the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP two , synchronously pumped interior to a MgO:PPLN femtosecond OPO, We've produced broadly tunable radiation throughout 5958�?117 nm using rapid static cavity delay tuning, having a optimum electrical power of 64 μW at 6791 nm, constrained because of the absorption in mirror substrates and also polarization-dependent intracavity losses.

This method makes it possible for the operation of commonly tunable optical parametric oscillators2 (OPO) and subsequent distinction frequency generators3 generating tunable pulses of substantial peak electricity. The higher Electricity from the pump pulse trains has certain Gains for that operation of a synchronously pumped OPO, e.g., peaceful stability demands, and also the likely to operate with huge cavity losses (e.g. steel mirrors) permitting massive tuning ranges with a single list of mirrors and high output-coupling aspects for pulse shortening.

In both equally the cases acquired unit mobile parameters are very same, which demonstrates the precision of present method. The electronic band constructions exhibit the semiconducting habits in both of those the cases. The density of states plot may also be studied and talked about.

We report new experimental success within the section-matching Houses of yellow colour HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm range. In addition, we present new Sellmeier equations that give a very good reproduction of your current experimental outcomes along with the released information factors for second-harmonic era of CO2 laser radiation at nine.

We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including sign and idler, it could be repeatedly tuned from 1.261 by way of 2.532 μm by different the pump wavelength. Two major advancements have been achieved, including the relationship in the signal and idler tuning ranges as well as the large output pulse Electricity with the signal and idler tuning ... [Clearly show complete summary] ranges. The main enhancement was reached by finding two particular sets of stage-matching angles. The next advancement was realized by making use of 5 sets of resonator mirrors for oscillating either signal or idler.

Two parametric four-wave-mixing (FWM) procedures in Rb atoms are analyzed applying perturbation concept under the affliction of rotating wave approximation. The two parametric FWM processes are coupled when they are thrilled coherently by a brief laser pulse by using a bandwidth encompassing the two corresponding upper energy levels in The 2 FWM procedures.

We present a numerical review for the look of successful MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top-hat transverse intensity profile, as well as a double-move pump cavity configuration. Particularly, we examine the result of area shape over the conversion performance. We regarded as two types of area buildings: "great vertical-wall" and "wedge-formed" domains and our numerical final results demonstrate that at better pump pulse energies, the conversion efficiency saturates, as well as the saturated effectiveness is nearly independent of your area designs.

The precise heat and thermal conductivity of HgGa2S4 are measured. It really is concluded that the combined properties of HgGa2S4 crystals can offer for them a number one place among the materials used in nonlinear-optical equipment for mid-IR-frequency conversion.

The third harmonic of CO2-laser radiation has actually been obtained by passing the laser beam via two CdGeAs2 crystals in tandem, with the primary crystal oriented for 2nd-harmonic technology and the second for sum mixing. Using this technique, We have now achieved a mean exterior conversion efficiency of 1.

The electronic structure and chemical bonding in HgGa2S4 crystals developed by vapor transport strategy are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is located being formed by splitted S 3p and Hg 6s states at binding energies BE=3 7 eV plus the parts at BE=seven 11 eV produced through the hybridization of S 3s and Ga 4s states with a powerful contribution from the Hg 5d states. At bigger binding energies the emission strains associated with the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed in the photoemission spectrum.
