two–10.8-µm wavelength area. Yet another vital limitation on the pump power related having a thermal lensing impact in crystal was resolute experimentally. A comparison was manufactured from AgGaSe2 and ZnGeP2 crystals as products well suited for the productive era of the second harmonic of cw CO2 laser radiation.

We create superior-purchase harmonics from crystalline solids using a tunable mid-IR OPA with fifty kHz repetition level. Using nonlinear self-compression in YAG crystals, we generate sub 3-cycle pulses at 3.eight μm wavelength for top harmonic spectroscopy. Read much more

0 Abstract Summary: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical products independently created by Chinese experts. Because of the excellent in depth overall performance and also the critical application benefit in laser sector, they've got attracted A lot interest at your home and overseas.

The progress of crystal development and laser output of BGSe and BGGSe are summarized, and the future development is prospected.

Throughout the previous a long time, mid-infrared (three–twelve μm) laser resources making use of crystals with nonlinear optical Homes have attracted a particular focus because of their possible apps in several fields such as optical counter-measures and distant chemical sensing. As transparency of popular oxide crystals is restricted to about 4 μm, many researches are already centered on chalcopyrite compounds as a consequence of their large transparency during the mid-IR variety as well as their solid nonlinear optical coefficients. You will find a require of this sort of crystals in a position to transform successfully the around infrared wavelengths from commercially obtainable lasers into wavelengths greater than five μm via Optical Parametric Oscillators (OPO) units.

A top quality BGGSe single crystal with measurement of thirty mm×ninety mm was grown by Bridgman-stockbarger strategy, and that is the very first in China. The profitable fabrication of BGGSe crystal equipment was also attained soon after orienting, reducing, and sprucing processes, which laid a strong Basis to the more software analysis with the crystal.

$ rm BaGa _2 rm GeSe _6$ (BGGSe) is often a freshly more info created nonlinear content which is beautiful for ultrabroad frequency mixing and ultrashort pulse technology resulting from its comparably reduced dispersion and substantial injury threshold. A numerical review reveals the fabric’s potential for octave-spanning mid-infrared pulse era approximately 18 µm. In a first experiment, we show that a lengthy crystal size of 2.
