ZnGeP2 crystal is the chief amid nonlinear crystals for middle IR. Huge sized Φtwenty×90 mm3 ZGP one crystals are already grown successfully with the vertical gradient freeze system. The crystallinity and optical properties of as-developed crystals had been measured by XRD and transmission spectra respectively.
2–ten.eight-µm wavelength location. Yet another critical limitation of your pump energy connected that has a thermal lensing result in crystal was resolute experimentally. A comparison was made of AgGaSe2 and ZnGeP2 crystals as resources suitable for the successful technology of the next harmonic of cw CO2 laser radiation.

We make significant-purchase harmonics from crystalline solids utilizing a tunable mid-IR OPA with fifty kHz repetition level. Making use of nonlinear self-compression in YAG crystals, we deliver sub 3-cycle pulses at three.8 μm wavelength for high harmonic spectroscopy. Go through extra

The uniaxial nonlinear crystals BaGa2GeS6 and BaGa2GeSe6 are characterized concerning thermal diffusivity and distinct warmth get more info above a temperature range of -90 to 250 °C for warmth propagation together and perpendicular towards the c -axis.
A thermo-optic dispersion method for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a 2 G e S e 6 nonlinear crystal is described. The experimentally established temperature-dependent stage-matching conditions for second-harmonic and sum-frequency era of Nd:YAG 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 2 laser and its harmonics during the 0.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is really a recently developed nonlinear substance that's eye-catching for ultrabroad frequency mixing and ultrashort pulse technology resulting from its comparably minimal dispersion and high hurt threshold. A numerical analyze shows the material’s capacity for octave-spanning mid-infrared pulse generation nearly eighteen µm. In a primary experiment, we exhibit that a lengthy crystal size of 2.
The pump pulse Power was managed by a variable diffraction attenuator. Its polarization was tuned by 90° which has a 50 percent-wave plate because it had to be ordinary wave inside the BGGSe (when AGS crystal was utilized, the sign beam polarization was tuned). The sign beam was focused by spherical mirror (M2, the focal duration of 2 m) into a gasoline tube of one.
