053 μm. The absorption spectrum of ammonia was presented to display the feasibility with the created optical parametric oscillator process for spectroscopic measurements and gas detection.
We report with a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based on the Kerr-lens-method-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP 2 , synchronously pumped interior to the MgO:PPLN femtosecond OPO, We've generated broadly tunable radiation across 5958�?117 nm applying immediate static cavity hold off tuning, that has a utmost electrical power of sixty four μW at 6791 nm, confined from the absorption in mirror substrates as well as polarization-dependent intracavity losses.
A list of ~450 noncentrosymmetric sulfides is noticed in reference to nonlinear optical properties. It's been found that to the plane in the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
.. [Clearly show total summary] 3rd-harmonic technology and parametric amplification with lower-frequency pumping in periodically poled Lively nonlinear crystals are also investigated. The Assessment is carried out for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Views of working with periodically poled active nonlinear crystals in laser gadgets with self-frequency conversion are mentioned.
We report new experimental outcomes within the stage-matching properties of yellow shade HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm range. In addition, we existing new Sellmeier equations that offer a excellent reproduction of your existing experimental benefits along with the posted knowledge factors for second-harmonic technology of CO2 laser radiation at nine.
The higher conversion efficiency and wide selection of radiation wavelength tuning makes it possible for to assume that this materials could contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the sizeable problem of huge dimensions crystals advancement method.
Although making use of an institutional account for this Site we don’t track any personalized, overall performance, functional or 1st or third social gathering linked info.
A method is made to solve the procedure of shortened equations describing parametric era in a one particular-frequency OPO cavity under nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals plus the optimal reflection coefficient on the output mirror are believed as opposed to the pump Electrical power density Wp at unique values from the OPO nonstationarity .
Bigger-buy nonlinear processes in different resources may also be regarded as along with a dialogue on content suitability for down-conversion of in the vicinity of-IR lasers into your mid-IR to satisfy numerous software necessities can be presented.
stabilize and tune the OPO, from which the strong etalon gave a far better overall performance. Temperature oscillations inside the PPLN crystal
The procedure is predicated on team velocity matching concerning interacting waves Along with birefringent section matching. We will describe broadband SHG features with regards to beam propagation Instructions, spectral positions of resonance, successful nonlinearities, spatial walk-offs among interacting get more info beams, and spectral bandwidths. The final results will show which the spectral bandwidths of the basic wave allowed for broadband SHG to achieve many countless nm. The corresponding SH spectral selection spans from 1758.58 to 4737.18 nm within the non-oxide crystals regarded as During this study. This kind of broadband SHG making use of quick pulse trains can likely be placed on frequency up-conversion imaging within the mid-IR area, in info transmission, As well as in nonlinear optical sign processing.
The observed file -to- 2 file frequency beats, originating directly from the OPO, can be utilized for self-referencing and period locking of the pump laser comb with no need for supercontinuum technology. With an average output electricity of �?thirty mW , this set up may very well be advantageous for various spectroscopic purposes inside the mid-IR.
An easy quantum design agrees nicely Along with the experimental final results and causes it to be doable to interpret the outcome regarding
Diode-pumped optical parametric oscillation continues to be shown for The very first time to our understanding in an individual Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions absorb the 812-nm radiation to deliver 1084-nm laser oscillation.
