and working situations for the sensible layout of higher electricity femtosecond optical parametric oscillators with excitation
Output idler energies over the microjoule level are obtained with optimum conversion efficiency of 11% for that amplifier phase, which is over two moments better than the outcome acquired with an analogous sample with the commonly spread material AgGaS 2 .
Other than the compactness and benign operating features, it absolutely was the big versatility in design and output characteristics that led on the accomplishment of strong-condition lasers during the last forty years.
.. [Present whole summary] 3rd-harmonic generation and parametric amplification with low-frequency pumping in periodically poled Lively nonlinear crystals are also investigated. The analysis is carried out for the case of the periodically poled Nd:Mg:LiNbO3 crystal. Views of using periodically poled active nonlinear crystals in laser products with self-frequency conversion are talked over.
on the laser emission wavelength. The minimum measured track record sign with the PA sensor (utilizing large purity
The substantial conversion performance and wide range of radiation wavelength tuning permits to assume that this materials might compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the considerable problem of big dimension crystals advancement approach.
The technology of tunable pico- and femtosecond gentle pulses with parametric frequency conversion processes has captivated greater focus recently1. New crystal components, as BBO, LBO, and KTP, with excellent nonlinearity and large damage threshold at the moment are obtainable, and pump lasers of enhanced balance enable the trustworthy Procedure of optical parametric oscillators. Parametric units pumped ... [Display whole abstract] both by cw modelocked lasers or by one rigorous ultrashort pulses are already developed. During this contribution parametric units are talked about that are pumped by powerful pulse trains of some microseconds length and repetition rates as much as 50Hz.
A technique is developed to unravel the technique of shortened equations describing parametric era inside of a one particular-frequency OPO cavity below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well check here as the optimal reflection coefficient on the output mirror are estimated compared to the pump Electrical power density Wp at diverse values from the OPO nonstationarity .
Modeling and experimental study on stage matching of 2nd harmonic technology in different coloration Hg Ga 2 S 4 crystals are completed. Utilizing the recognised Sellmeier equations, the dispersion relation with weighting proportionally to short-wavelength boundary from the crystal transparency band is proposed.
stabilize and tune the OPO, from which the good etalon gave a better performance. Temperature oscillations while in the PPLN crystal
... The initial knowledge about the refractive index of orange HGS released by Levine et al. [35] involved only handful of wavelengths within the visible and near-IR equally as an illustration in the feasibility of the crystal for birefringent section-matching. The refractive indices for that orange stage were calculated and tabulated among 0.
for your detection of molecular trace gasses. The oscillation threshold, output power and security of The one resonant
In this particular paper we theoretically examine essentially the most productive pump temporal shape for pulsed operation of optical parametric oscillators (OPOs). The theoretical analysis consists of solving the optimal control problem using the level equation formalism. The OPO ideal buildup conduct is derived for just about any OPO configuration, and we present that the optimal pump pulse condition is usually a double rectangle. The main rectangle is optimized to the buildup method, whilst the 2nd 1 is optimized for the continual state, and the two count otherwise within the OPO mirror reflectivities along with the available pump Electricity and optimum peak ability.
3% rms over twelve h in fantastic beam high-quality. The in the vicinity of-IR sign pulses through the OPO Have a very Gaussian pulse duration of �?19 ps , calculated at 1284 nm. Now we have investigated the temperature tuning properties with the OPO and in comparison the data With all the theoretical calculations utilizing The newest Sellmeier equations and thermo-optic coefficients to the crystal. To the most beneficial of our awareness, Here is the very first picosecond OPO depending on CSP functioning at MHz repetition charges.
