it enables the realization of all-optical processes based on the nonlinear coefficients in the XY plane, such as all-optical polarization rotation in PPLN, as well as multipartite entanglement experiments based
The nonlinear coefficients of a number of widely used nonlinear crystals has been remeasured recently using second harmonic generation by Eckardt et. al. [33]. The nonlinear coefficient values obtained for KDP agreed with previous measurements but values for BBO, LiIO3, MgO:LiNbO3 and KTP were...

Standard optical-grade Z-cut LiNbO3 crystals of 0.5 mm in thickness were used. First, we deposited a thin layer of photoresist onto the +Z surface of the crystal, which was then lithographically patterned with the designed chirped lattices. The exposed area was brought into contact with ...
N-dimethylamino-4'-N'-methyl-stilbazolium 2,4,6-trimethylbenzenesulfonate are used[8], which typically exhibit a very strong nonlinearity (with electro-optic coefficients >100 pm/V, two orders of magnitude higher than for typical inorganic crystals). This allows the efficient terahertz conversion...
The tuning of second (SHG) and third (THG) harmonic emission is studied in the model system LiNb 1−𝑥 1−xTa 𝑥 xO 3 3 (0≤𝑥≤10≤x≤1, LNT) between the established edge compositions lithium niobate (LiNbO 3 3, 𝑥=0x=0, LN) and lithium tantalate (LiTaO 3 3, 𝑥=...
Crystals which are non-critically phase-matched in acrystal ovenmay exhibit problems when the crystal temperature is changed too rapidly or too often. In particular,anti-reflection coatingsmay be damaged due to different thermal expansion coefficients of the involved materials. ...

As opposed to conventional frequency-converted UV laser sources, which have high power consumption, high cost, and low efficiency, the laser sources of this invention ...
