Optical parametric oscillator pumped at ~one µm with intracavity mid-IR distinction-frequency era in OPGaAs
We report with a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser given that the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP two , synchronously pumped internal to your MgO:PPLN femtosecond OPO, We've got created broadly tunable radiation across 5958�?117 nm making use of rapid static cavity hold off tuning, with a highest electricity of sixty four μW at 6791 nm, limited via the absorption in mirror substrates and also polarization-dependent intracavity losses.
This method lets the operation of greatly tunable optical parametric oscillators2 (OPO) and subsequent change frequency generators3 producing tunable pulses of significant peak power. The higher Strength with the pump pulse trains has specified benefits for the operation of the synchronously pumped OPO, e.g., relaxed stability needs, as well as the potential to operate with massive cavity losses (e.g. steel mirrors) making it possible for large tuning ranges with a single list of mirrors and high output-coupling factors for pulse shortening.
.. [Clearly show total abstract] 3rd-harmonic era and parametric amplification with small-frequency pumping in periodically poled Energetic nonlinear crystals can also be investigated. The Examination is completed for the situation of a periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of applying periodically poled Lively nonlinear crystals in laser units with self-frequency conversion are reviewed.
We report new experimental outcomes to the phase-matching Houses of yellow color HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-ten.5910 μm assortment. On top of that, we existing new Sellmeier equations that supply a superior copy on the existing experimental benefits in addition to the revealed data details for 2nd-harmonic technology of CO2 laser radiation at nine.
The calculated Main amount binding energies are as opposed with People of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being impartial around the technological situations of crystal growth. In distinction towards the valence band spectrum, the distribution of electron states while in the bandgap of HgGa2S4 crystals is identified being strongly dependent upon the technological situations of crystal expansion as shown with the photoluminescence analysis.
The temperature dependence of refractive indices of optical resources is characterised On this function by what we simply call their normalized thermo-optic coefficients. They are decided experimentally by interferometric measurements of thermal expansion and of variations in optical thickness at a couple of laser wavelengths as perform of temperature. An appropriate vectorial formalism applied to these information makes it possible for predicting the thermal evolution with the refractive index everywhere in the useful range of transparency.

The technologies of escalating mercury thiogallate crystals (HgGa2S4) is improved and substantial-excellent bulk samples are manufactured. The basic optical and thermal Qualities of these crystals are studied. The transmission spectra of mercury thiogallate are measured and its nonlinear traits like the quadratic susceptibility, tuning curves, as well as optical-destruction resistance are also decided.
The procedure is based on team velocity matching in between interacting waves As well as birefringent section matching. We'll explain broadband SHG attributes when it comes to beam propagation Instructions, spectral positions of resonance, efficient nonlinearities, spatial wander-offs concerning interacting beams, and spectral bandwidths. The final results will display that the spectral bandwidths of the elemental wave authorized for broadband SHG to reach various a huge selection of nm. The corresponding SH spectral selection spans from 1758.fifty eight to 4737.eighteen nm in the non-oxide crystals regarded in this research. Such broadband SHG making use of limited pulse trains can most likely be placed on frequency up-conversion imaging from the mid-IR area, in facts transmission, and in nonlinear optical signal processing.

Mid-IR next-buy NLO crystal is indispensable during the frequency conversion applications inside the mid-IR area. When compared with DUV and UV/Vis/in the vicinity of-IR NLO crystals, realistic mid-IR NLO crystals are rather scarce, and a lot of of these are still on the stage of laboratory study. This chapter testimonials the modern progress around the mid-IR NLO crystals, which mainly includes expanding the classical mid-IR NLO crystals into large high-high-quality types or into quasi-phase-matching buildings which can be ideal for the laser equipment by different advancement strategies and Checking out new possible mid-IR NLO crystals by introducing new style HgGa2S4 Crystal and design and synthesis tactics.
Distinction frequency mixing of strongly centered Gaussian beams in periodically poled LiNbO3 was investigated. The beams were centered In the crystal without having destruction. Mixing of cw and pulsed laser techniques was used to minimize the thermal lensing outcomes inside of this crystal.
