BaGa4Se7 (BGSe) and BaGa2GeSe(BGGSe) crystals are novel infrared nonlinear optical resources independently created by Chinese scientists. Due to great extensive effectiveness as well as essential software benefit in laser market, they have attracted Considerably consideration at your house and abroad.
2–10.8-µm wavelength location. One more vital limitation of the pump energy related using a thermal lensing influence in crystal was resolute experimentally. A comparison was crafted from AgGaSe2 and ZnGeP2 crystals as elements well suited for the economical technology of the second harmonic of cw CO2 laser radiation.

New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are synthesized. The constructions of each BaGa2GeS6 and BaGa2GeSe6 had been identified to be isomorphous exhibiting A 3-dimensional framework built by the parallel alignment of Ga or Ge tetrahedron teams alongside the c-aix. The ultraviolet transmittance spectrum indicates the shorter-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We generate high-order harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition rate. Using nonlinear self-compression in YAG crystals, we deliver sub three-cycle pulses at three.eight μm wavelength for high harmonic spectroscopy. Browse a lot more
New middle infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) happen to be synthesized. The constructions of both of those BaGa2GeS6 and BaGa2GeSe6 were identified to generally be isomorphous exhibiting A 3-dimensional framework constructed by the parallel alignment of Ga or Ge tetrahedron groups along the c-aix. The ultraviolet transmittance spectrum signifies the short-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
A thermo-optic dispersion system for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a two G e S e 6 nonlinear crystal is reported. The experimentally identified temperature-dependent stage-matching conditions for next-harmonic and sum-frequency era of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O 4 (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O four (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O 2 laser and its harmonics within the 0.
Intraband magnetotransmission and magnetophotoconductivity have been calculated up to eighteen T using CO2 laser strains. The cyclotron resonance and merged resonance harmonics are utilised to find out the exchange interaction within an HgMnTe crystal. The experiment also evidences the freezing of electrons while in the donor point out. Examine additional

It has been discovered the optical nonlinear coefficients d31 and d22 in LiNbO3 are of opposite signal, in disagreement by having an previously report by Many others. This is an important consideration for optimizing nonlinear optical interactions in LiNbO3.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is really a freshly designed nonlinear material that may be interesting for ultrabroad frequency mixing and ultrashort pulse era due to its comparably very low dispersion and large damage threshold. A numerical review exhibits the fabric’s capacity for octave-spanning mid-infrared pulse era nearly eighteen µm. In a first experiment, we exhibit that a long crystal length of 2.
The pump pulse energy was managed by a variable diffraction attenuator. Its polarization was tuned by ninety° having a fifty percent-wave plate since it had to be everyday wave in the BGGSe (when AGS crystal was employed, the sign beam polarization was tuned). The signal beam was focused by spherical mirror (M2, the focal duration of 2 m) right into a gasoline tube of one.
