2–10.eight-µm wavelength location. One more important limitation in the pump electric power related having a thermal lensing effect in crystal was firm experimentally. A comparison was crafted from AgGaSe2 and ZnGeP2 crystals as materials suitable for the effective era of the 2nd harmonic of cw CO2 laser radiation.

We existing new experimental benefits to the phase-matching Homes of the not long ago uncovered BaGa2GeSe6

We crank out high-purchase harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition level. Making use of nonlinear self-compression in YAG crystals, we crank out sub a few-cycle pulses at 3.8 μm wavelength for high harmonic spectroscopy. Read through additional

The dislocations are traced via the repetition of etching from epitaxial layer on the interface. The results show that dislocations during the substrates are expected to bend alongside the direction standard to the epitaxial progress way with the interface.

0 Summary Summary: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical resources independently made by Chinese scientists. Due to outstanding complete overall performance as well as significant software price in laser sector, they have attracted Significantly consideration at your house and overseas.

The development of crystal growth and laser output of BGSe and BGGSe are summarized, and the long run enhancement is prospected.

Barium gallium germanium selenium (BaGa2GeSe6, BGGSe) crystal is usually a novel infrared nonlinear more info optical materials with great efficiency, which was learned by Chinese scientists. To this point, there is no report on huge dimensions one crystal development of the crystal in China. During this research, polycrystalline BGGSe was synthesized productively by making use of a self-made two-zone furnace with the amount of 400 g in a single operate.

BaGa2GeSe6 crystals are useful for nonlinear optical frequency conversion in their transparency variety. The wavelengths at which highest conversion efficiencies might be obtained along with the tuning array for change-frequency technology are found.
