Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variation-frequency technology in OPGaAs
Outcomes of thermal conductivity measurements are described for a number of of the greater just lately formulated nonlinear optical crystals. New or significantly revised values of thermal conductivity were being received in 6 products. Noteworthy thermal conductivities calculated were being People for AgGaS2 [0.014 W/(cm K) and 0.
A list of ~450 noncentrosymmetric sulfides has actually been observed in reference to nonlinear optical Homes. It has been observed that on the plane in the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned into a rosette of two intersected ellipses of «acentricity».
Scientific studies of practical pump laser systems ideal for ultrafast femtosecond OPOs based on CdSiP 2 are mentioned, and the favorable linear and nonlinear optical Houses, in addition to distinctive period-matching properties of CdSiP two , are presented working with The newest Sellmeier equations for the material. The described experimental results signify the highest output pulse Vitality and document regular ability in the ultrafast picosecond and femtosecond time scales over the 6–seven μm spectral selection to date.
OPO have been improved by optimizing pump beam waistline and OPO cavity length. Both air-spaced and stable etalons were examined to frequency
The calculated core stage binding energies are when compared with Those people of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being impartial about the technological problems of crystal progress. In contrast towards the valence band spectrum, the distribution of electron states within the bandgap of HgGa2S4 crystals is discovered to be strongly dependent on the technological disorders of crystal advancement as shown with the photoluminescence Examination.
The temperature dependence of refractive indices of optical materials is characterized With this function by what we simply call their normalized thermo-optic coefficients. They are established experimentally by interferometric measurements of thermal expansion and of adjustments in optical thickness at some laser wavelengths as function of temperature. A suitable vectorial formalism applied to these information lets predicting the thermal evolution of the refractive index all over the valuable number of transparency.

The specific warmth and thermal conductivity of HgGa2S4 are click here calculated. It truly is concluded the mixed properties of HgGa2S4 crystals can offer for them a leading situation among the resources used in nonlinear-optical devices for mid-IR-frequency conversion.
stabilize and tune the OPO, from which the good etalon gave a far better performance. Temperature oscillations in the PPLN crystal
Very simple process for lowering the depolarization loss resulting from thermally induced birefringence in strong-state lasers
to the detection of molecular trace gasses. The oscillation threshold, output electricity and security of The only resonant
A straightforward quantum product agrees very well Together with the experimental benefits and makes it possible to interpret the outcome concerning
This is actually the first example of a broadband OPO working over the molecular fingerprint location, and we display its prospective by conducting broadband Fourier-renovate spectroscopy employing drinking water vapor and also a polystyrene reference normal.
