053 μm. The absorption spectrum of ammonia was introduced to demonstrate the feasibility with the designed optical parametric oscillator system for spectroscopic measurements and gasoline detection.
We report on a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) based upon the Kerr-lens-mode-locked Ti:sapphire laser since the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based on the nonlinear crystal, CdSiP 2 , synchronously pumped inner to some MgO:PPLN femtosecond OPO, We now have generated broadly tunable radiation across 5958�?117 nm employing fast static cavity hold off tuning, by using a maximum ability of sixty four μW at 6791 nm, constrained from the absorption in mirror substrates and also polarization-dependent intracavity losses.
This technique lets the operation of greatly tunable optical parametric oscillators2 (OPO) and subsequent big difference frequency generators3 creating tunable pulses of significant peak power. The upper Power on the pump pulse trains has specified Rewards to the operation of the synchronously pumped OPO, e.g., peaceful balance prerequisites, as well as the possible to work with huge cavity losses (e.g. metal mirrors) enabling massive tuning ranges with one list of mirrors and large output-coupling components for pulse shortening.
Experiments of viable pump laser technologies well suited for ultrafast femtosecond OPOs depending on CdSiP 2 are discussed, along with the favorable linear and nonlinear optical Homes, as well as exclusive stage-matching traits of CdSiP two , are presented utilizing The newest Sellmeier equations for the material. The described experimental final results signify the very best output pulse energy and file regular electrical power in the ultrafast picosecond and femtosecond time scales across the 6–seven μm spectral selection to this point.
We report new experimental success about the phase-matching Attributes of yellow colour HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-10.5910 μm vary. Also, we present new Sellmeier equations that give a very good reproduction with the current experimental results as well as the printed data factors for next-harmonic generation of CO2 laser radiation at nine.
This double rectangle is quantitatively described and is particularly according to past outcomes reported within the literature. Also, numerical simulations are utilized to validate our analytical design with a doubly resonant OPO and exhibit regular outcomes. The numerical simulations also exhibit that an optimum major-hat temporal profile could give performances extremely near the ones accomplished with the best double rectangle.
Taxonomy, chemical bonding relations and nonlinear optical Houses of noncentrosymmetric sulfide crystals
Pumping mid-IR optical parametric oscillators near one μm is appealing for its simplicity and electric power scaling capacity. To this aim, vast bandgap non-oxide nonlinear crystals are desired.
Additionally, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and disclosed that the spectral profile of your output from the CPOPO was relevant to both equally the parametric get profile of the nonlinear crystal as well as the intra-cavity substantial-purchase dispersion.
The third harmonic of CO2-laser radiation is attained by passing the laser beam by means of two CdGeAs2 crystals in tandem, with the 1st crystal oriented for second-harmonic here era and the next for sum mixing. Using This method, We now have reached an average exterior conversion effectiveness of one.
... The primary data within the refractive index of orange HGS posted by Levine et al. [35] incorporated only several wavelengths within the seen and in the vicinity of-IR just as an illustration with the feasibility of this crystal for birefringent stage-matching. The refractive indices to the orange section were measured and tabulated amongst 0.
The noticed f -to- two f frequency beats, originating straight from the OPO, may be used for self-referencing and phase locking with the pump laser comb with no need for supercontinuum technology. With an average output ability of �?30 mW , this set up may be effective for many different spectroscopic purposes while in the mid-IR.
The latest mid-IR NLO crystals could be divided into 4 classes, i.e., classical binary and ternary metal pnictides and chalcogenides, quaternary steel chalcogenides, binary and ternary metallic halides, and different-bond-form hybrid compounds that comprise at least two sorts of naturally various chemical bonds in the crystal constructions. Metallic pnictides and chalcogenides have acquired A lot consideration on developing significant crystals. Various-bond-type hybrid is a whole new family of mid-IR NLO products, and plenty of of these had been located in the last decade. In metal halide process, equally progress in expanding significant crystals and getting new ones are actually manufactured.
3% rms above twelve h in very good beam high quality. The around-IR signal pulses from your OPO Have a very Gaussian pulse period of �?19 ps , measured at 1284 nm. Now we have investigated the temperature tuning traits with the OPO and compared the information with the theoretical calculations employing The newest Sellmeier equations and thermo-optic coefficients for your crystal. To the ideal of our knowledge, This is actually the initially picosecond OPO based on CSP working at MHz repetition premiums.
