.. [Present entire summary] parametric oscillator. The two independently targeted beams were being built to overlap In the crystal. The concentrating parameters of The 2 beams were being with regards to the similar. The concentrating operate made by Boyd and Kleinman for tightly concentrated beams was prolonged to periodically poled crystals so that you can healthy the temperature-tuning curve. A 0.sixty six%/W performance was received for the main difference frequency mixing procedure.

The importance in the attained final results lies in the fact that to get the similar conversion in SHG or DFM, 1 now calls for essential enter radiation with Substantially lower intensity.

crystals with ultrafast Yb-ion laser pump is proposed. The results form a beneficial reference for the selection of supplies

Research of feasible pump laser systems well suited for ultrafast femtosecond OPOs depending on CdSiP two are talked over, and also the favorable linear and nonlinear optical Homes, together with unique stage-matching properties of CdSiP two , are introduced using the most recent Sellmeier equations for the fabric. The described experimental outcomes symbolize the very best output pulse Vitality and file regular electric power during the ultrafast picosecond and femtosecond time scales throughout the 6–7 μm spectral assortment to this point.

We report new experimental effects within the stage-matching Attributes of yellow color HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-ten.5910 μm range. On top of that, we current new Sellmeier equations that supply a superior reproduction on the existing experimental benefits along with the released data points for next-harmonic generation of CO2 laser radiation at 9.

The superior conversion effectiveness and wide selection of radiation wavelength tuning makes it possible for to assume that this substance may possibly compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the sizeable issues of big sizing crystals progress course of action.

The era of tunable pico- and femtosecond gentle pulses with parametric frequency conversion processes has captivated improved awareness recently1. New crystal products, as BBO, LBO, and KTP, with outstanding nonlinearity and large harm threshold are now available, and pump lasers of improved balance allow the dependable operation of optical parametric oscillators. Parametric products pumped ... [Show whole abstract] both by cw modelocked lasers or by single powerful ultrashort pulses have been made. In this particular contribution parametric methods are talked over which are pumped by intensive pulse trains of a few microseconds length and repetition costs as much as 50Hz.

We existing a numerical study for the design of successful MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top rated-hat transverse depth profile, plus a double-go pump cavity configuration. Specifically, we look into the influence of domain shape on the conversion efficiency. We thought of two sorts of area constructions: "great vertical-wall" and "wedge-shaped" domains and our numerical benefits present that at larger pump pulse energies, the conversion effectiveness saturates, and also the saturated efficiency is nearly unbiased of your area styles.

The particular warmth and thermal conductivity of HgGa2S4 are calculated. It is concluded which the merged Houses of HgGa2S4 crystals can offer for them a leading place among the materials Utilized in nonlinear-optical gadgets for mid-IR-frequency conversion.

stabilize and tune the OPO, from which the stable etalon gave a greater efficiency. Temperature oscillations within the PPLN crystal

Normalization of your absorption alerts within the PAD is completed according to the absorption signals during the fuel-stuffed

Quantum mechanical dependent initially principle calculations happen to be employed to acquire the device cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite construction for The very first time. For this, we dealt with HgGa2S4 in two different types of internet site symmetries in the identical space team.

A straightforward quantum product agrees perfectly Using the experimental final results and makes it achievable to interpret the influence with regard to

3% rms over 12 h in very good beam high quality. The in close proximity to-IR sign pulses in the OPO Have a very Gaussian pulse HgGa2S4 Crystal period of �?19 ps , measured at 1284 nm. We now have investigated the temperature tuning properties in the OPO and when compared the information Along with the theoretical calculations making use of The latest Sellmeier equations and thermo-optic coefficients for the crystal. To the most beneficial of our awareness, Here is the initially picosecond OPO based upon CSP running at MHz repetition costs.
