spectral variety. Additionally, we present new Sellmeier equations that provide a excellent replica in the
One more application of this set up is seeding significant-strain CO2-laser amplifier [seventeen]. It ought to be famous that presented set up from the mid-IR laser process is pretty easy and has a fantastic prospective for Strength scalability. Electricity in the entrance-conclude Ti:sapphire laser may be increased nearly many Joules [12], even so that pump laser would require a broad-aperture BGGSe crystal sample. Also, the DFG pulse Electricity could be amplified by an advancement of signal pulse�?uniform spectrum condition and enhanced energy.

A thermo-optic dispersion components for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a two G e S e six nonlinear crystal is reported. The experimentally determined temperature-dependent stage-matching circumstances for next-harmonic and sum-frequency technology of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O 4 (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O four (RTA) optical parametric oscillators in addition to a CO2 rm CO _2 C O 2 laser and its harmonics from the 0.
The progress of crystal growth and laser output of BGSe and BGGSe are summarized, and the longer term advancement is prospected.

Laser-induced problems threshold on the nonlinear crystals BaGa4Se7 and BaGa2GeSe6 at 2091 nm from the nanosecond regime
24% and that is comparable with one particular obtained with higher repetition amount reduced-Strength laser systems like in [9]. Making an allowance for a likelihood to raise pump pulse Vitality of our set up approximately ~10 mJ, the DFG pulse Electricity is often improved approximately ~24 μJ at the identical efficiency, nevertheless, it essential a large-aperture, ~fifteen mm in diameter BGGSe sample. Normal DFG pulse Electrical power in AGS was not confidently measured with Ophir-3A electricity meter as a consequence of its reduced signal.
A thermo-optic dispersion method for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a two G e S e six nonlinear crystal is claimed. The experimentally established temperature-dependent section-matching disorders for 2nd-harmonic and sum-frequency generation of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O 4 (KTP) and RbTiOAsO4 rm RbTiOAsO _4 R b T i O A s O 4 (RTA) optical parametric oscillators as well as a CO2 rm CO _2 C O two laser and its harmonics in the 0.
$ rm BaGa _2 rm GeSe _6$ (BGGSe) is really a freshly produced nonlinear substance that may be desirable for ultrabroad frequency mixing and ultrashort pulse technology resulting from its comparably lower dispersion and high damage threshold. A numerical review shows the fabric’s capability for octave-spanning mid-infrared pulse technology as many as eighteen µm. In a first experiment, we show that a lengthy crystal duration of two.
It is actually revealed that there are wavelength combinations at which the efficient nonlinearity coefficient varies only slightly in a broad frequency band.
BaGa2GeSe6 crystals are useful for nonlinear optical frequency conversion inside their transparency assortment. The wavelengths at which maximum conversion efficiencies is usually acquired and the tuning vary for difference-frequency technology are located.
