AgGaSe2 Crystal Things To Know Before You Buy

Defect-similar absorption and luminescence had been revealed and a method to decrease them was recommended. The electronic framework, density of states, and several optical Houses have been calculated from the 1st concepts for Li2In2GeSe6. Calculated nonlinear coefficients and relatively big birefringence reveal a solid section-matching capability. These investigations display that Li2In2GeSe6 is actually a promising mid-infrared nonlinear optical crystal.

Preliminary experiments have indicated that this stoichiometry-dependent mid-IR absorption in AgGaSe(two) crystals may very well be significantly diminished by optimization of the method parameters throughout crystal progress and annealing.

for example LixAg1−xGaS2 and LixAg1−xGaSe2, the structural distortions in LixAg1−xInSe2 are a great deal more outstanding.

Optical rectification in a chalcopyrite AgGaSe2 crystal for broadband terahertz radiation era

The use of a LiTaO(3) retarder is prompt check here to realize an orthogonal state of polarization between OPO outputs that are needed for productive pumping of a AgGaSe(two) crystal.

This will likely explain the confined crystallization region while in the section graph from the tetragonal structure LixAg1−xInSe2.

radiation technology. During this do the job, we successfully synthesize and mature a new NLO chalcogenide crystal

Typically, not all solutions to the above questions are "Certainly", so you have to stike a equilibrium among these factors to discover the greatest Remedy for the programs. For instance, to get a SHG crystal for Ti:Sapphire laser at 800nm, with the heart beat width of 40fs, and the predicted pulse broadening influence below 20fs. KTP, AgGaSe2 or AgGaS2 can't attain stage matching of SHG800nm; LiIO3's problems threshold will not be substantial enough; The two BBO and KDP are ideal, nevertheless, BBO's conversion effieicy is increased than KDP, and 100micron BBO SHG800nm can only make pulse broadening outcome of 19fs.
