2–10.eight-µm wavelength location. A further important limitation from the pump energy connected using a thermal lensing impact in crystal was determined experimentally. A comparison was manufactured from AgGaSe2 and ZnGeP2 crystals as resources suitable for the economical technology of the next harmonic of cw CO2 laser radiation.

$ rm BaGa _2 rm GeSe _6$ (BGGSe) is usually a recently made nonlinear product which is beautiful for ultrabroad frequency mixing and ultrashort pulse technology due to its comparably low dispersion and significant harm threshold. A numerical study reveals the fabric’s ability for octave-spanning mid-infrared pulse era as many as eighteen µm. In a first experiment, we present that an extended crystal length of 2.

The pump pulse Electrical power was controlled by a variable diffraction attenuator. Its polarization was tuned by 90° which has a half-wave plate since it had to be standard wave within the BGGSe (when AGS crystal was employed, the sign beam polarization was tuned). The sign beam was targeted by spherical mirror (M2, the focal size of 2 m) into a gasoline tube of one.

The nature of this instability and DFG Electricity decrease is just not apparent for us. Certainly one of the reasons is often connected that has a nonlinear absorption and plasma development, respectively, that triggers reflection/scattering/absorption with the longwave mid-IR pulse. The dependence of BGGSe transmittance on pump pulse energy is presented in Fig.
