053 μm. The absorption spectrum of ammonia was presented to show the feasibility of your created optical parametric oscillator process for spectroscopic measurements and gasoline detection.
The significance of your acquired final results lies in the fact that to obtain the similar conversion in SHG or DFM, one now demands essential enter radiation with Substantially reduced intensity.
crystals with ultrafast Yb-ion laser pump is proposed. The results sort a helpful reference for the choice of materials
The strategy of chemical transport reactions (volatilization of a material by means of a reduced-risky chemical intermediate at a temperature T1 and back again-reaction from the combination in a temperature T2, utilizing the temperature dependence with the chemical equilibrium included) can be a beneficial tool for rising one crystals of many materials which cannot be conveniently attained within the melt.
We report new experimental benefits over the period-matching Homes of yellow colour HgGa2S4 crystals for harmonic era of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-ten.5910 μm variety. Also, we existing new Sellmeier equations that offer a good reproduction of your current experimental final results plus the printed knowledge details for next-harmonic technology of CO2 laser radiation at 9.
This double rectangle is quantitatively described and is also in step with previous outcomes noted within the literature. Also, numerical simulations are used to validate our analytical product on a doubly resonant OPO and demonstrate reliable success. The numerical simulations also clearly show that an optimal top-hat temporal profile could deliver performances really near those achieved with the exceptional double rectangle.
The era of tunable pico- and femtosecond light pulses with parametric frequency conversion processes has captivated greater notice recently1. New crystal supplies, as BBO, LBO, and KTP, with outstanding nonlinearity and large hurt threshold at the moment are available, and pump lasers of improved stability enable the dependable operation of optical parametric oscillators. Parametric equipment pumped ... [Present complete summary] possibly by cw modelocked lasers or by solitary rigorous ultrashort pulses are developed. With this contribution parametric methods are talked about which are pumped by rigorous pulse trains of a few microseconds period and repetition costs approximately 50Hz.
We present a numerical analyze for the design of effective MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of major-hat transverse depth profile, in addition to a double-move pump cavity configuration. Specifically, we look into the effect of area condition within the conversion performance. We regarded as two sorts of domain structures: "perfect vertical-wall" and "wedge-shaped" domains and our numerical success present that at bigger pump pulse energies, the conversion efficiency saturates, as well as saturated efficiency is sort of unbiased of your area styles.
Vibrational spectra of Li-containing nonlinear crystals and their software in THz radiation generation are discussed. Using an illustration of LiGaS2, the defect impact on spectroscopic traits is revealed. Large-temperature annealing in an appropriate environment makes it possible for 1 to get rid of prolonged and position defects also to improve the transparency. Vitality construction and parameters of key place defects for example anion vacancy (File-Heart) and cation antisite defect GaLi check here calculated from the primary concepts concur well With all the experimental benefits.
stabilize and tune the OPO, from which the sound etalon gave a much better efficiency. Temperature oscillations while in the PPLN crystal
... The main data over the refractive index of orange HGS released by Levine et al. [35] provided only handful of wavelengths within the obvious and in the vicinity of-IR just as an indication with the feasibility of this crystal for birefringent stage-matching. The refractive indices for your orange period had been calculated and tabulated in between 0.
for that detection of molecular trace gasses. The oscillation threshold, output power and steadiness of The only resonant
Solitary-stage sub-two hundred fs mid-infrared generation from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Tunable mid-IR radiation is obtained for the duration of next harmonic era of tunable CO2-laser radiation employing a CdGeAs2 crystal. Its angular tuning attributes for the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
