Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency era in OPGaAs
Benefits of thermal conductivity measurements are claimed for many of the greater just lately formulated nonlinear optical crystals. New or significantly revised values of thermal conductivity ended up obtained in six resources. Notable thermal conductivities measured ended up those for AgGaS2 [0.014 W/(cm K) and 0.
crystals with ultrafast Yb-ion laser pump is proposed. The results variety a useful reference for the choice of materials
An easy system for cutting down the decline that is due to depolarization ensuing from thermally induced tension birefringence in strong-condition lasers is described. The procedure uses just one intracavity quarter-wave plate with its speedy or gradual axis aligned parallel to the popular airplane of polarization, outlined by an intracavity polarizer.
We report new experimental outcomes within the period-matching Qualities of yellow color HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm selection. Additionally, we current new Sellmeier equations that supply a superior copy on the current experimental success together with the revealed data factors for 2nd-harmonic era of CO2 laser radiation at nine.
The measured Main amount binding energies are when compared with People of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to get unbiased about the technological situations of crystal growth. In contrast to the valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is observed to get strongly dependent on the technological situations of crystal growth as shown from the photoluminescence Examination.
Taxonomy, chemical bonding relations and nonlinear optical Attributes of noncentrosymmetric sulfide crystals
We present a numerical analyze for the design of effective MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of leading-hat transverse intensity profile, as well as a double-go pump cavity configuration. Specifically, we examine the outcome of domain form within the conversion performance. We considered two kinds of area constructions: "ideal vertical-wall" and "wedge-shaped" domains and our numerical final results demonstrate that at bigger pump pulse energies, the conversion effectiveness saturates, and also the saturated performance is almost independent from the area shapes.
Moreover, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled the spectral profile with the output from the CPOPO was suitable to equally the parametric achieve profile in the nonlinear crystal as well as the intra-cavity superior-get dispersion.
Subjects is often refined further more inside the search engine results. The Topic facet will expose the high-stage subject areas connected to the content returned in the search engine results. Specific COLLECTIONS
Interference is noticed in between the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
Observe: Creator names are going to be searched while in the keywords and phrases industry, also, but that may uncover papers exactly where the person is outlined, as an alternative to papers they authored.
The chosen nonlinear crystals show bigger nonlinear conversion efficiency when compared with AgGaS 2 , with BaGa 2 GeS six On top of that offering a narrower angular spectrum of spontaneous parametric down conversion, useful in interferometric schemes. Our conclusions set up a pathway for integrating State-of-the-art crystal technologies into mid-infrared metrology and imaging units, placing the phase for long run developments in nonlinear interferometry and spectroscopy.
Change frequency mixing of strongly focused Gaussian beams in periodically poled LiNbO3 get more info was investigated. The beams had been targeted In the crystal without having problems. Mixing of cw and pulsed laser units was used to attenuate the thermal lensing results inside of this crystal. A minimal-electricity cw one.064‐μm Nd:YAG laser beam was made use of given that the pump, Whilst the sign beam arrived from a picosecond optical .
