Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency generation in OPGaAs
One particular observes a spectacular rise in technology of the next harmonic together with the demodulation indicators compared to the pump wave amplitude. A transparent correlation exists among these nonlinear signatures and the amount of damages. Preliminary determinations from the coefficient of quadratic nonlinearity are already attained. The outcome while in the configuration of parametric emitting antenna are thought to generally be the quite initial on cracked products.

Reports of feasible pump laser systems well suited for ultrafast femtosecond OPOs based on CdSiP 2 are discussed, as well as the favorable linear and nonlinear optical properties, and also unique stage-matching attributes of CdSiP 2 , are introduced making use of The newest Sellmeier equations for the material. The explained experimental results depict the very best output pulse Electricity and record ordinary electric power during the ultrafast picosecond and femtosecond time scales over the 6–7 μm spectral vary so far.
We report new experimental outcomes to the section-matching Houses of yellow colour HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-ten.5910 μm selection. Moreover, we existing new Sellmeier equations that provide a good copy with the existing experimental success along with the revealed facts factors for 2nd-harmonic technology of CO2 laser radiation at 9.
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which include signal and idler, it could be consistently tuned from one.261 by means of two.532 μm by varying the pump wavelength. Two main enhancements had been obtained, including the link of the signal and idler tuning ranges and the large output pulse Power through the signal and idler tuning ...

The next advancement was understood through the use of five sets of resonator mirrors for oscillating both signal or idler.
The temperature dependence of refractive indices of optical components is characterised With this perform by what we contact their normalized thermo-optic coefficients. These are identified experimentally by means of interferometric measurements of thermal expansion and of modifications in optical thickness at some laser wavelengths as operate of temperature. An appropriate vectorial formalism applied to these facts allows predicting the thermal evolution of your refractive index everywhere in the valuable variety of transparency.
Determined by the theories of stage matching and appropriate composition ratio, the affect of composition ratio over the frequency conversions of two types (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration of corresponding sellmeier equations, period matching diagrams of second harmonic era and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers had been calculated, and acceptable composition ratios with several compositions.
Modeling and experimental review on period matching of second harmonic generation in different color Hg Ga two S 4 crystals are performed. Using the recognized Sellmeier equations, the dispersion relation with weighting proportionally to small-wavelength boundary on the crystal transparency band is proposed.

Simple process for lowering the depolarization reduction ensuing from thermally induced birefringence in strong-condition lasers
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser method. By using a 300 μm prolonged magnesium-doped periodically poled LiNbO 3 crystal as the parametric attain medium and configuring the OPO for a chirped-pulse oscillator, we obtained mid-infrared emission acquiring an instantaneous bandwidth covering 3084�?466 nm. This final result signifies, to the very best of our knowledge, the widest instantaneous bandwidth acquired from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous potential of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-speedy OPOs.
A pulsed TEA CO2 laser was used to analyze the impact of pump radiation parameters (mode composition, wavelength, and pulse period), focusing circumstances, absorption coefficient, and temperature over the efficiency of conversion into the 2nd harmonic and on angular dependences of section matching in ZnGeP2 crystals. Excellent agreement betweeen experimental and theoretical success is observed. Read through more
