We derive express expressions from the frame in the optical indicatrix for the next-get successful nonlinearity in biaxial crystals with issue groups 2, m, and one, governing the conversion performance in three-wave nonlinear optical interactions. The tabulated expressions for that monoclinic symmetry classes two and m are valid for all possible orientations of the optical indicatrix relative into the crystallographic body and for propagation alongside an arbitrary course outdoors the principal planes. They can be used for direct estimation of the productive nonlinearity in the same body the place the phase-matching loci are calculated.
We current new experimental benefits to the stage-matching Qualities of your not too long ago uncovered BaGa2GeSe6

We produce large-order harmonics from crystalline solids utilizing a tunable mid-IR OPA with fifty kHz repetition fee. Applying nonlinear self-compression in YAG crystals, we generate sub 3-cycle pulses at three.8 μm wavelength for high harmonic spectroscopy. Examine extra

The experimentally established temperature-dependent stage-matching ailments for next-harmonic and sum-frequency technology 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 4 (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O 2 laser and its harmonics inside the 0.
The progress of crystal expansion and laser output of BGSe and BGGSe are summarized, and the long run progress is prospected.

Laser-induced hurt threshold in the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm within the nanosecond routine
24% that's equivalent with one particular attained with large repetition level reduced-Electricity laser systems like in [9]. Bearing in mind a possibility to improve pump pulse Vitality of our setup around ~ten mJ, the DFG pulse Electricity may be amplified as much as ~24 μJ at the identical effectiveness, on the other hand, it demanded a broad-aperture, ~15 mm in diameter BGGSe sample. Regular DFG pulse Strength in AGS was not confidently measured with Ophir-3A power meter due to its low sign.
A thermo-optic dispersion components for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a 2 G e S e six nonlinear crystal is documented. The experimentally determined temperature-dependent period-matching situations for next-harmonic and sum-frequency generation of Nd:YAG more info laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O four (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 two laser and its harmonics within the 0.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is a recently designed nonlinear substance that's desirable for ultrabroad frequency mixing and ultrashort pulse era on account of its comparably lower dispersion and superior injury threshold. A numerical review displays the fabric’s capacity for octave-spanning mid-infrared pulse generation as many as eighteen µm. In a primary experiment, we exhibit that a lengthy crystal duration of two.
The pump pulse energy was managed by a variable diffraction attenuator. Its polarization was tuned by ninety° that has a 50 percent-wave plate mainly because it had to be normal wave while in the BGGSe (when AGS crystal was used, the signal beam polarization was tuned). The signal beam was concentrated by spherical mirror (M2, the focal length of two m) right into a fuel tube of one.
BaGa2GeSe6 crystals are used for nonlinear optical frequency conversion in their transparency vary. The wavelengths at which maximum conversion efficiencies might be received and also the tuning variety for variance-frequency technology are uncovered.
