two–10.8-µm wavelength region. One more vital limitation with the pump ability connected by using a thermal lensing outcome in crystal was determined experimentally. A comparison was made of AgGaSe2 and ZnGeP2 crystals as resources well suited for the effective era of the next harmonic of cw CO2 laser radiation.
We current new experimental results for that stage-matching properties with the just lately identified BaGa2GeSe6

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 documented. The experimentally established temperature-dependent stage-matching situations for second-harmonic and sum-frequency generation 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 in addition to a CO2 rm CO _2 C O 2 laser and its harmonics inside the 0.
The progress of crystal advancement and laser output of BGSe and BGGSe are summarized, and the longer term enhancement is prospected.

A high quality BGGSe solitary crystal with measurement of thirty mm×ninety mm was developed by Bridgman-stockbarger system, that's the get more info 1st in China. The effective fabrication of BGGSe crystal products was also accomplished following orienting, chopping, and sharpening processes, which laid a good foundation for your further more application investigation on the crystal.
It's been observed the optical nonlinear coefficients d31 and d22 in LiNbO3 are of opposite sign, in disagreement having an before report by Other folks. This is a vital consideration for optimizing nonlinear optical interactions in LiNbO3.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is usually a freshly made nonlinear product that may be interesting for ultrabroad frequency mixing and ultrashort pulse technology resulting from its comparably very low dispersion and significant hurt threshold. A numerical examine displays the material’s capacity for octave-spanning mid-infrared pulse technology as many as eighteen µm. In a first experiment, we show that a lengthy crystal size of 2.
The pump pulse Strength was managed by a variable diffraction attenuator. Its polarization was tuned by 90° with a 50 percent-wave plate because it had to be everyday wave while in the BGGSe (when AGS crystal was used, the signal beam polarization was tuned). The sign beam was focused by spherical mirror (M2, the focal size of two m) into a gasoline tube of one.
BaGa2GeSe6 crystals are utilized for nonlinear optical frequency conversion within their transparency selection. The wavelengths at which utmost conversion efficiencies is usually obtained and also the tuning variety for big difference-frequency era are identified.
