Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variance-frequency era in OPGaAs
Outcomes of thermal conductivity measurements are reported for quite a few of the more not long ago developed nonlinear optical crystals. New or substantially revised values of thermal conductivity had been received in six materials. Notable thermal conductivities calculated had been Those people for AgGaS2 [0.014 W/(cm K) and 0.
A list of ~450 noncentrosymmetric sulfides has become observed in reference to nonlinear optical Houses. It's been uncovered that to the plane with the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
A straightforward technique for lowering the decline that is due to depolarization ensuing from thermally induced strain birefringence in stable-condition lasers is noted. The strategy works by using one intracavity quarter-wave plate with its speedy or gradual axis aligned parallel to the preferred aircraft of polarization, defined by an intracavity polarizer.
Within this perform, we current what on earth is, to our awareness, the first measurements from the quantum phase diffusion noise of a cw OPO. Go through a lot more
PA Ref-cell, which substantially lowers themeasurement glitches with the methane focus in thecase of instability
Optical Attributes of orange phased HgGa2S4 crystal is investigated. Generation of tunable Center infrared radiation by 2nd harmonic of tunable CO2 laser radiation has actually been shown. 2nd harmonic conversion effectiveness with respect to other infrared crystal has also been mentioned.
A way is developed to resolve the procedure of shortened equations describing parametric era inside of a one-frequency OPO cavity website below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals as well as the ideal reflection coefficient of the output mirror are believed compared to the pump Power density Wp at distinct values from the OPO nonstationarity .

stabilize and tune the OPO, from which the good etalon gave a far better performance. Temperature oscillations from the PPLN crystal
... The initial facts over the refractive index of orange HGS released by Levine et al. [35] provided only few wavelengths within the visible and close to-IR just as an indication from the feasibility of this crystal for birefringent section-matching. The refractive indices with the orange period have been calculated and tabulated between 0.
12 μm and describe all frequency conversion strategies realized to this point with them as well as upcoming prospective purposes. Key phrases: Ternary and quaternary semiconductors, defect chalcopyrites, stable methods, nonlinear optical crystals, mid-infrared
Solitary-phase sub-200 fs mid-infrared generation from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Difference frequency mixing of strongly centered Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been centered inside the crystal without hurt. Mixing of cw and pulsed laser devices was utilized to minimize the thermal lensing outcomes inside of this crystal. A reduced-energy cw one.064‐μm Nd:YAG laser beam was utilised as being the pump, whereas the signal beam arrived from a picosecond optical .
