Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency technology in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) determined by the Kerr-lens-mode-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP two , synchronously pumped interior to a MgO:PPLN femtosecond OPO, We now have produced broadly tunable radiation throughout 5958�?117 nm employing quick static cavity delay tuning, by using a greatest electricity of 64 μW at 6791 nm, constrained with the absorption in mirror substrates and also polarization-dependent intracavity losses.

.. [Present comprehensive summary] third-harmonic era and parametric amplification with very low-frequency pumping in periodically poled Lively nonlinear crystals are also investigated. The analysis is carried out for the situation of a periodically poled Nd:Mg:LiNbO3 crystal. Views of utilizing periodically poled active nonlinear crystals in laser products with self-frequency conversion are talked about.
Self-referenced octave-huge subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
The calculated Main level binding energies are when compared with those of HgS, Gasoline, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being independent over the technological problems of crystal development. In contrast to your valence band spectrum, the distribution of electron states in the bandgap of HgGa2S4 crystals is uncovered to become strongly dependent on the technological situations of crystal development as demonstrated by the photoluminescence Assessment.
Whilst utilizing an institutional account for this Web site we don’t keep track of any particular, effectiveness, useful or 1st or 3rd party relevant data.
Pumping mid-IR optical parametric oscillators around 1 μm is eye-catching for its simplicity and electricity scaling capacity. To this aim, broad bandgap non-oxide nonlinear crystals are essential.
In addition, we carried out a numerical simulation of chirped-pulse OPOs (CPOPOs) and disclosed which the spectral profile in the output from a CPOPO was suitable to both the parametric obtain profile of your nonlinear crystal as well as the intra-cavity significant-buy dispersion.
stabilize and tune the OPO, from which the solid etalon gave a better general performance. Temperature oscillations while in the PPLN crystal
... The main information about the refractive index of orange HGS released by Levine et al. [35] integrated only several wavelengths within the seen and in the vicinity of-IR just as an illustration of your feasibility of this crystal for birefringent period-matching. The refractive indices with the orange phase had been calculated and tabulated concerning 0.
The noticed f -to- two f frequency beats, originating directly from the OPO, may be used for self-referencing and stage locking of your pump click here laser comb with no need for supercontinuum generation. With a median output energy of �?thirty mW , this setup is likely to be useful for a number of spectroscopic purposes within the mid-IR.
The selected nonlinear crystals exhibit larger nonlinear conversion performance when compared to AgGaS 2 , with BaGa two GeS 6 Moreover providing a narrower angular spectrum of spontaneous parametric down conversion, advantageous in interferometric techniques. Our findings set up a pathway for integrating advanced crystal systems into mid-infrared metrology and imaging techniques, placing the phase for potential developments in nonlinear interferometry and spectroscopy.
Difference frequency mixing of strongly focused Gaussian beams in periodically poled LiNbO3 was investigated. The beams were focused inside the crystal without damage. Mixing of cw and pulsed laser methods was employed to attenuate the thermal lensing consequences inside of this crystal. A lower-electric power cw 1.064‐μm Nd:YAG laser beam was utilised as being the pump, Whilst the signal beam came from a picosecond optical .
