We report on the femtosecond optical parametric oscillator (OPO) for your 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 two , synchronously pumped inside to some MgO:PPLN femtosecond OPO, We've got generated broadly tunable radiation across 5958�?117 nm employing quick static cavity delay tuning, by using a most energy of 64 μW at 6791 nm, restricted because of the absorption in mirror substrates as well as polarization-dependent intracavity losses.

.. [Clearly show total abstract] 3rd-harmonic era and parametric amplification with small-frequency pumping in periodically poled active nonlinear crystals can also be investigated. The Assessment is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of employing periodically poled Energetic nonlinear crystals in laser equipment with self-frequency conversion are discussed.
Self-referenced octave-extensive subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser

The temperature dependence of refractive indices of optical resources is characterized With this get the job done by what we phone their normalized thermo-optic coefficients. They're decided experimentally by way of interferometric measurements of thermal growth and of alterations in optical thickness at several laser wavelengths as function of temperature. An acceptable vectorial formalism placed on these details enables predicting the thermal evolution in the refractive index all around the beneficial array of transparency.
air gap and excited in collection by a typical pump beam. The stage of the interference is determined by the section shifts at 3 frequencies.
The specific warmth and thermal conductivity of HgGa2S4 are calculated. It is concluded which the mixed Homes of HgGa2S4 crystals can provide for them a leading placement Amongst the components Utilized in nonlinear-optical equipment for mid-IR-frequency conversion.
Assessment of recent, promising large-band-hole nonlinear crystals with the mid-IR is offered. We focused on ternary and quaternary chalcogenides more info and based on their own physical and chemical Qualities, which Besides linear and nonlinear optical properties, figure out the efficiency of crystal usage in particular laser experiments. The correlation involving the composition, framework and output parameters plus the trends in alterations of the principle features for example band hole, nonlinear susceptibility, laser harm threshold, and many others, are demonstrated.

We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser method. By employing a three hundred μm prolonged magnesium-doped periodically poled LiNbO 3 crystal as the parametric achieve medium and configuring the OPO to be a chirped-pulse oscillator, we acquired mid-infrared emission owning an instantaneous bandwidth masking 3084�?466 nm. This end result signifies, to the ideal of our knowledge, the widest instantaneous bandwidth received from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous possible of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-fast OPOs.
A pulsed TEA CO2 laser was applied to research the result of pump radiation parameters (mode framework, wavelength, and pulse duration), focusing disorders, absorption coefficient, and temperature over the efficiency of conversion into the second harmonic and on angular dependences of stage matching in ZnGeP2 crystals. Very good agreement betweeen experimental and theoretical final results is noticed. Examine more
Big difference frequency mixing of strongly centered Gaussian beams in periodically poled LiNbO3 was investigated. The beams were being concentrated inside the crystal without having injury. Mixing of cw and pulsed laser units was utilized to attenuate the thermal lensing outcomes inside this crystal. A very low-electricity cw one.064‐μm Nd:YAG laser beam was utilised as the pump, whereas the signal beam came from a picosecond optical .
