.. [Display full abstract] parametric oscillator. The two independently targeted beams were produced to overlap In the crystal. The focusing parameters of The 2 beams ended up with regards to the very same. The concentrating function produced by Boyd and Kleinman for tightly centered beams was prolonged to periodically poled crystals so that you can fit the temperature-tuning curve. A 0.sixty six%/W performance was obtained for the main difference frequency mixing system.
Results of thermal conductivity measurements are documented for quite a few of the greater just lately made nonlinear optical crystals. New or considerably revised values of thermal conductivity ended up attained in 6 products. Noteworthy thermal conductivities calculated had been These for AgGaS2 [0.014 W/(cm K) and 0.
crystals with ultrafast Yb-ion laser pump is proposed. The outcome type a valuable reference for the choice of resources
.. [Display whole summary] 3rd-harmonic generation and parametric amplification with very low-frequency pumping in periodically poled Energetic nonlinear crystals also are investigated. The Evaluation is performed for the situation of a periodically poled Nd:Mg:LiNbO3 crystal. Views of making use of periodically poled Lively nonlinear crystals in laser equipment with self-frequency conversion are reviewed.
Self-referenced octave-wide subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it could be consistently tuned from 1.261 through two.532 μm by varying the pump wavelength. Two main enhancements were attained, including the relationship in the sign and idler tuning ranges as well as high output pulse Strength in the signal and idler tuning ... [Clearly show total abstract] ranges. The primary advancement was attained by identifying two distinct sets of section-matching angles. The 2nd improvement was recognized by using 5 sets of resonator mirrors for oscillating both signal or idler.
The temperature dependence of refractive indices of optical supplies is characterized With this work by what we phone their normalized thermo-optic coefficients. These are definitely identified experimentally as a result of interferometric measurements of thermal growth and of improvements in optical thickness at a handful of laser wavelengths as functionality of temperature. A suitable vectorial formalism placed on these facts will allow predicting the thermal evolution of your refractive index all over the practical range of transparency.
Based upon the theories of period matching and acceptable composition ratio, the affect of composition ratio on the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thing to consider of corresponding sellmeier equations, section matching diagrams of 2nd harmonic generation and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers were calculated, together with satisfactory composition ratios with a variety of compositions.
Modeling and experimental examine on period matching of second harmonic generation in various shade Hg Ga two S 4 crystals are performed. Using the known Sellmeier equations, the dispersion relation with weighting proportionally to limited-wavelength boundary with the crystal transparency band is proposed.
Evaluation of latest, promising broad-band-gap nonlinear crystals for your mid-IR is given. We centered on ternary and quaternary chalcogenides and dependent on their own physical and chemical properties, which Along with linear and nonlinear optical Homes, determine the effectiveness of crystal usage in certain laser experiments. The correlation amongst the composition, framework and output parameters along with the trends in adjustments of the most crucial attributes like band gap, nonlinear susceptibility, laser destruction threshold, and so on, are shown.
The strategy is based get more info on team velocity matching in between interacting waves In combination with birefringent phase matching. We are going to explain broadband SHG properties concerning beam propagation Instructions, spectral positions of resonance, successful nonlinearities, spatial wander-offs involving interacting beams, and spectral bandwidths. The outcomes will exhibit the spectral bandwidths of the fundamental wave permitted for broadband SHG to reach numerous numerous nm. The corresponding SH spectral range spans from 1758.fifty eight to 4737.18 nm in the non-oxide crystals thought of Within this research. These types of broadband SHG applying small pulse trains can potentially be applied to frequency up-conversion imaging within the mid-IR region, in information and facts transmission, and in nonlinear optical signal processing.
twelve μm and explain all frequency conversion schemes understood to this point with them along with long term possible purposes. Keywords and phrases: Ternary and quaternary semiconductors, defect chalcopyrites, sound alternatives, nonlinear optical crystals, mid-infrared
On this paper we theoretically look into quite possibly the most successful pump temporal shape for pulsed operation of optical parametric oscillators (OPOs). The theoretical Investigation is made of resolving the optimal Handle dilemma using the rate equation formalism. The OPO ideal buildup actions is derived for any OPO configuration, and we exhibit which the ideal pump pulse form is really a double rectangle. The main rectangle is optimized with the buildup course of action, although the 2nd 1 is optimized with the steady condition, and both rely differently about the OPO mirror reflectivities as well as the available pump Electricity and optimum peak electric power.
This is the initial illustration of a broadband OPO functioning throughout the molecular fingerprint area, and we show its potential by conducting broadband Fourier-change spectroscopy applying water vapor plus a polystyrene reference conventional.
