ZnGeP2 crystal may be the leader among nonlinear crystals for middle IR. Large sized Φtwenty×ninety mm3 ZGP one crystals are developed efficiently via the vertical gradient freeze procedure. The crystallinity and optical properties of as-grown crystals have been measured by XRD and transmission spectra respectively.

New Center infrared nonlinear optical crystals of BaGa2GeX6(X=S, Se) are synthesized. The constructions of equally BaGa2GeS6 and BaGa2GeSe6 have been uncovered for being isomorphous exhibiting A 3-dimensional framework made by the parallel alignment of Ga or Ge tetrahedron groups together the c-aix. The ultraviolet transmittance spectrum indicates the small-wavelength absorption edges of BaGa2GeS6 and BaGa2GeSe6 are 380 nm and 440 nm, respectively.
We deliver substantial-get harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition level. Using nonlinear self-compression in YAG crystals, we make sub a few-cycle pulses at 3.eight μm wavelength for top harmonic spectroscopy. Examine more
