Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variation-frequency era in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) for that deep-infrared (deep-IR) based upon the Kerr-lens-method-locked Ti:sapphire laser as the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP 2 , synchronously pumped inside to your MgO:PPLN femtosecond OPO, We've generated broadly tunable radiation throughout 5958�?117 nm working with immediate static cavity hold off tuning, having a greatest electric power of sixty four μW at 6791 nm, constrained by the absorption in mirror substrates as well as polarization-dependent intracavity losses.
crystals with ultrafast Yb-ion laser pump is proposed. The outcome sort a practical reference for the choice of supplies
The significant conversion effectiveness and wide selection of radiation wavelength tuning makes it possible for to anticipate that this content may perhaps contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the significant trouble of huge sizing crystals development approach.
We report new experimental final results around the phase-matching properties of yellow colour HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-10.5910 μm vary. Furthermore, we existing new Sellmeier equations that provide a great reproduction from the present experimental success together with the released info factors for 2nd-harmonic generation of CO2 laser radiation at nine.
prompted oscillations while in the idler wavelength of under 200MHz about 300s; the small-time period security was under 3MHz
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are researched employing perturbation concept under the situation of rotating wave approximation. The 2 parametric FWM procedures are coupled when they are energized coherently by a brief laser pulse with a bandwidth encompassing the two corresponding upper energy degrees in the two FWM processes.
This new edition has become up-to-date and revised to includeimportant developments, concepts and systems that haveemerged Considering that the publication of the primary edition.
The precise heat and thermal conductivity of HgGa2S4 are calculated. It can be concluded which the combined Homes of HgGa2S4 crystals can provide for them a number one place among the materials used in nonlinear-optical units for mid-IR-frequency conversion.
Examination of new, promising extensive-band-hole nonlinear crystals to the mid-IR is presented. We centered on ternary and quaternary chalcogenides and dependent on their physical and chemical Homes, which Along with linear and nonlinear optical properties, identify the efficiency of crystal utilization in selected laser experiments. The correlation between the composition, construction and output parameters along with the traits in variations of the key qualities which include band hole, nonlinear susceptibility, laser injury threshold, etcetera, are demonstrated.
... The primary information over the refractive index of orange HGS revealed by Levine et al. [35] included only handful of wavelengths during the obvious and close to-IR just as an indication in the feasibility of this crystal for birefringent section-matching. The refractive indices for your orange section were being calculated and tabulated between 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser procedure. By utilizing a three hundred μm extensive magnesium-doped periodically poled LiNbO three crystal as the parametric get medium and configuring the OPO like a chirped-pulse oscillator, we acquired mid-infrared emission acquiring an instantaneous bandwidth masking 3084�?466 nm. This final result represents, to the very best of our awareness, the widest instantaneous bandwidth obtained from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous opportunity of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-speedy OPOs.
Recent mid-IR NLO crystals is usually divided into 4 groups, i.e., classical binary and ternary steel pnictides and chalcogenides, quaternary steel chalcogenides, binary and ternary metal halides, and get more info unique-bond-style hybrid compounds that include at the very least two sorts of definitely different chemical bonds during the crystal buildings. Metal pnictides and chalcogenides have bought A great deal notice on growing large crystals. Distinctive-bond-kind hybrid is a different household of mid-IR NLO components, and many of these were being located in the final 10 years. In metallic halide process, the two development in expanding substantial crystals and getting new types are actually produced.
Tunable mid-IR radiation is received in the course of next harmonic technology of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning attributes with the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
