“…Gayraud et al have devised a novel design of PBFs for methane sensing at 3.2 μm [100]. Using a femtosecond optical parametric oscillator as an optical source and Fourier transform infrared (FTIR) spectroscopy [101], they reported that 1000 ppm of methane can be measured and predicted that the sensitivity could be improved so as to measure concentrations up to 50 ppm with the use of the recently emerging new light sources [100].…”

We experimentally investigate the parameters affecting parametric transfer in a SPOPO for indirect shaping of MIR ultrashort pulses and make comparisons with previously reported numerical modeling. The individual effects of the parameters are discussed in detail. We conclude that signal bandwidth narrowing, minimal signal amplification, large pump depletion, cavity length tuning and minimal pump and idler temporal walk-off are required for high fidelity transfer, which we are able to demonstrate for a strongly chirped pump pulse.

“…An acoustical tone burst in the crystal makes it special in the field of acoustics and ultrasonics [5][6][7] . LiNbO 3 finds its application also in the field of holographic imaging, optical waveguides and modern optical parametric oscillators [8][9][10] . Its large spontaneous polarization and non linear optical activity make it favorite in the thermal, electrical and optical areas 11,12 .…”

Abstract:The second and third-order elastic constants and pressure derivatives of second-order elastic constants of trigonal LiNbO 3 (lithium niobate) have been obtained using the deformation theory. The strain energy density estimated using finite strain elasticity is compared with the strain dependent lattice energy density obtained from the elastic continuum model approximation. The second-order elastic constants and the non-vanishing third-order elastic constants along with the pressure derivatives of trigonal LiNbO 3 are obtained in the present work. The second and third-order elastic constants are compared with available experimental values. The second-order elastic constant 11 C which corresponds to the elastic stiffness along the basal plane of the crystal is less than 33 C which corresponds to the elastic stiffness tensor component along the c-axis of the crystal. The pressure derivatives, dp C d ij / ′ obtained in the present work, indicate that trigonal LiNbO 3 is compressible. The higher order elastic constants are used to find the generalized Gruneisen parameters of the elastic waves propagating in different directions in LiNbO 3 . The Brugger gammas are evaluated and the low temperature limit of the Gruneisen gamma is obtained. The results are compared with available reported values.
