With the advent of new nonlinear resources and one-frequency pump resources, There's renewed curiosity in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly both equally amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
A mode-locked tunable dye laser continues to be made that's synchronously pumped at superior repetition fees through the doubled output of a mode-locked Nd:YAG laser. The dye laser provides rigorous pulses of 35 psec length which can be widely tunable, of in the vicinity of-rework-restricted bandwidth, As well as in time coincidence Together with the pumping pulses.
crystals with ultrafast Yb-ion laser pump is proposed. The effects kind a helpful reference for the selection of resources
In both equally the conditions obtained unit mobile parameters are exact same, which reveals the accuracy of present approach. The electronic band buildings show the semiconducting conduct in both equally the conditions. The density of states plot are also analyzed and mentioned.
We report new experimental outcomes over the period-matching Homes of yellow colour HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-ten.5910 μm array. Furthermore, we present new Sellmeier equations that offer a excellent replica in the existing experimental outcomes as well as the released data factors for next-harmonic generation of CO2 laser radiation at 9.
In this particular Introduction We are going to provide a shorter overview of the critical milestones in the event of reliable-state lasers, focus on the range of performance parameters attainable Using these lasers, and point out key apps.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are examined utilizing perturbation concept under the problem of rotating wave approximation. The two parametric FWM procedures are coupled when they're energized coherently by a short laser pulse by using a bandwidth encompassing the two corresponding upper Power ranges in the two FWM procedures.
We present a numerical analyze for the look of effective MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of best-hat transverse depth profile, and also a double-pass pump cavity configuration. Especially, we look into the result of domain condition to the conversion effectiveness. We regarded as two forms of domain structures: "fantastic vertical-wall" and "wedge-shaped" domains and our numerical results exhibit that at larger pump pulse energies, the conversion efficiency saturates, plus the saturated efficiency is nearly independent with the domain styles.
Vibrational spectra of Li-that contains nonlinear crystals as well as their application in THz radiation era are talked over. Applying an example of LiGaS2, the defect impact on spectroscopic characteristics is proven. Significant-temperature annealing in a proper atmosphere permits just one to eliminate extended and stage defects and also to Enhance the transparency. Electrical power structure and parameters of primary stage defects including anion vacancy (F-center) and cation antisite defect GaLi calculated from the initial ideas agree properly Along with the experimental success.
stabilize and tune the OPO, from which the sound etalon gave a much better functionality. Temperature oscillations inside the PPLN crystal
Very simple technique for decreasing the depolarization reduction ensuing from thermally induced birefringence in reliable-condition lasers

During this paper we theoretically examine one of the most effective pump temporal shape for pulsed Procedure of click here optical parametric oscillators (OPOs). The theoretical Evaluation consists of fixing the optimum Command dilemma using the level equation formalism. The OPO ideal buildup behavior is derived for almost any OPO configuration, and we present which the best pump pulse shape is often a double rectangle. The initial rectangle is optimized with the buildup approach, when the second one particular is optimized for the constant point out, and each rely differently within the OPO mirror reflectivities and also the obtainable pump Electricity and maximum peak electrical power.
three% rms above 12 h in very good beam high-quality. The near-IR sign pulses from your OPO Have got a Gaussian pulse period of �?19 ps , calculated at 1284 nm. We've investigated the temperature tuning properties from the OPO and in comparison the data With all the theoretical calculations making use of the most recent Sellmeier equations and thermo-optic coefficients for your crystal. To the very best of our information, This can be the initially picosecond OPO based on CSP working at MHz repetition premiums.
