ZnGeP2 crystal may be the leader among nonlinear crystals for Center IR. Substantial sized Φ20×90 mm3 ZGP one crystals are grown efficiently from the vertical gradient freeze system. The crystallinity and optical Attributes of as-grown crystals had been calculated by XRD and transmission spectra respectively.

We create significant-buy harmonics from crystalline solids employing a tunable mid-IR OPA with fifty kHz repetition charge. Working with nonlinear self-compression in YAG crystals, we create sub 3-cycle pulses at three.eight μm wavelength for top harmonic spectroscopy. Study a lot more
The dislocations are traced because of the repetition of etching from epitaxial layer to the interface. The outcomes clearly show that dislocations while in the substrates are expected to bend along the course regular to the epitaxial progress direction in the interface.
0 Abstract Summary: BaGa4Se7 (BGSe) and BaGa2GeSe6 (BGGSe) crystals are novel infrared nonlinear optical materials independently developed by Chinese researchers. As a result of excellent comprehensive efficiency as well as important application benefit in laser sector, they've got attracted Substantially awareness at your house and overseas.
Due to exceptional comprehensive functionality and also the significant application worth in laser field, they've captivated much interest at your house and abroad. The progress of crystal expansion and laser output of BGSe and BGGSe are summarized, and the longer term enhancement check here is prospected.
77Growth of the new higher-overall performance NLO crystal BaGa2GeSe6 via the managed vapor force strategy
Subject areas might be refined even more while in the search engine results. The Topic facet will expose the substantial-degree topics affiliated with the content returned inside the search results. Exclusive COLLECTIONS
24% which happens to be comparable with a single received with superior repetition rate reduced-Vitality laser programs like in [9]. Making an allowance for a probability to boost pump pulse Electrical power of our setup nearly ~ten mJ, the DFG pulse Power might be enhanced around ~24 μJ at the same performance, even so, it essential a broad-aperture, ~fifteen mm in diameter BGGSe sample. Regular DFG pulse energy in AGS wasn't confidently measured with Ophir-3A power meter as a consequence of its low signal.
A thermo-optic dispersion system for BaGa2GeSe6 rm BaGa _2 rm GeSe _6 B a G a 2 G e S e six nonlinear crystal is claimed. The experimentally established temperature-dependent phase-matching situations for second-harmonic and sum-frequency technology of Nd:YAG laser-pumped KTiOPO4 rm KTiOPO _4 K T i O P O four (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 2 laser and its harmonics during the 0.
The best frequency conversion performance of ten⁻⁴ was obtained for a comparatively new PbIn6Te10 crystal, that's an buy of magnitude increased than past outcomes.
The pump pulse energy was controlled by a variable diffraction attenuator. Its polarization was tuned by ninety° having a 50 percent-wave plate because it needed to be normal wave from the BGGSe (when AGS crystal was employed, the sign beam polarization was tuned). The signal beam was centered by spherical mirror (M2, the focal length of 2 m) right into a gas tube of one.
