Based upon our research, we also suggest a whole new plan for development of compact significant-energy OPO resources using MgO:PPLN chips of somewhat brief lengths and huge cross-sectional place.
We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) determined by the Kerr-lens-method-locked Ti:sapphire laser as the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP 2 , synchronously pumped inner to a MgO:PPLN femtosecond OPO, We've produced broadly tunable radiation throughout 5958�?117 nm making use of quick static cavity hold off tuning, that has a utmost ability of sixty four μW at 6791 nm, limited from the absorption in mirror substrates together with polarization-dependent intracavity losses.
crystals with ultrafast Yb-ion laser pump is proposed. The results variety a beneficial reference for the choice of resources
By applying intracavity dispersion Management, in close proximity to-remodel-confined signal pulses of �?one hundred fs duration with clean single-peak spectrum are attained at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the top of our know-how, This can be The very first time this sort of realistic idler powers from the deep-IR have been generated from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition amount.
A laser fuel analyzer is suitable for determining the composition of exhaled air via photoacoustic spectroscopy. The analyzer, depending on a broadband optical parametric oscillator and photoacoustic detector, supplies superior-precision fast Examination of your multicomponent composition of human exhaled air for dynamic estimation in the effectiveness of managing bronchus and lung diseases.
The higher conversion performance and wide range of radiation wavelength tuning permits to be expecting that this substance may compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the considerable trouble of huge sizing crystals advancement process.
The temperature dependence of refractive indices of optical supplies is characterised During this work by what we connect with their normalized thermo-optic coefficients. These are definitely determined experimentally by way of interferometric measurements of thermal enlargement and of modifications in optical thickness at a number of laser wavelengths as functionality of temperature. An acceptable vectorial formalism placed on these data permits predicting the thermal evolution on the refractive index everywhere in the helpful array of transparency.
Based on the theories of section matching and satisfactory composition ratio, the impact of composition ratio around the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thing to consider of corresponding sellmeier equations, phase matching diagrams of next harmonic era and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers have been calculated, and appropriate composition ratios with numerous compositions.
Vibrational spectra of Li-containing nonlinear crystals as well as their application in THz radiation era are talked about. Utilizing an illustration of LiGaS2, the defect effect on spectroscopic characteristics is revealed. Significant-temperature annealing click here in a suitable ambiance will allow a single to remove extended and point defects and also to Increase the transparency. Strength construction and parameters of main issue defects which include anion vacancy (F-Heart) and cation antisite defect GaLi calculated from the first rules concur effectively Together with the experimental results.
The know-how of developing mercury thiogallate crystals (HgGa2S4) is enhanced and significant-high-quality bulk samples are generated. The basic optical and thermal Attributes of these crystals are researched. The transmission spectra of mercury thiogallate are measured and its nonlinear characteristics like the quadratic susceptibility, tuning curves, plus the optical-destruction resistance will also be determined.
The defect chalcopyrite crystal HgGa2S4 has become used inside of a 1064-nm pumped optical parametric oscillator to generate Nonlinear crystals for optical parametric oscillators pumped by light-weight pulses of close to IR lasers...
Quantum mechanical primarily based initially basic principle calculations are already utilized to obtain the unit cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite composition for the first time. For this, we taken care of HgGa2S4 in two different types of web site symmetries in a similar Area group.
With this paper we theoretically look into quite possibly the most economical pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical analysis contains fixing the exceptional control dilemma using the charge equation formalism. The OPO best buildup behavior is derived for just about any OPO configuration, and we present the ideal pump pulse condition is really a double rectangle. The initial rectangle is optimized for that buildup approach, even though the next one particular is optimized to the constant state, and both of those rely in different ways within the OPO mirror reflectivities in addition to the accessible pump Vitality and most peak electric power.
