XRD requires shining a beam of X-rays onto the crystal and measuring the intensity and direction with the scattered X-rays. By analyzing the scattered X-rays, the crystal composition and orientation is usually established.
LBO has this sort of great transmittance that it may even be accustomed to crank out 266 nanometer light, although the absorption under 300nm is mostly way too high for that conversion to get valuable. In addition it displays Excellent efficiency for frequency conversion normally.
Lithium triborate (LBO) nonlinear crystal is Probably the most applied crystal for harmonics era for short and very long pulse programs. As a consequence of it’s rather tiny walkoff angle extensive crystals can be employed what allows to obtain significant conversion efficiency. A Particular circumstance of LBO crystal software is a non-essential period matching (NCPM) for harmonics technology.
XRD may also be used to determine the crystal high quality and defects within the crystal, like twinning and dislocations.
The vast majority of common nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from inventory. Customer-distinct Proportions and AR coatings are provided at competitive prices.
A typical technique for getting ultrathin crystals will be to first optically contact a thicker nonlinear crystal with some substrate (e.g. of fused silica) after which you can to polish the crystal right down to the essential thickness of e.
X-ray diffraction is a strong technique for identifying the crystal structure and orientation of LBO nonlinear crystals.
GWU-Lasertechnik gives all conventional nonlinear crystals like LBO, BBO and KTP having a broad number of specifications. Beside the well-proven elements, progressive crystals like CLBO or BiBO with remarkable Houses for e. g. deep-UV era or large-electrical power ultrashort pulse lasers can be obtained. Regardless of if unique parts for R & D applications are demanded or cost-productive quantities in little, medium or significant batches with in-time shipping and delivery with the manufacturing line are needed: GWU’s committed support helps to locate the finest Main components on your software.
In several cases, a nonlinear crystal useful for nonlinear frequency conversion has a very long lifetime, which is for a longer period than that of The full laser system. The crystal substance is essentially not modified through Procedure. Having said that, a lessened crystal life time can happen underneath different circumstances:
Non-linear Optical (NLO) crystals offer an enormously flexible Answer for building new wavelengths from existing, off-the-shelf laser resources. The optical wavelength spectrum is utilized by a large and continuously growing selection of apps, from producing of health-related lasers, quantum networking & computing through to environmental sensing and a lot of Other people.
Superior depth, limited pulse lasers with quick wavelengths have enabled several production procedures, or enhanced the effects attained from extra common lasers. Those properties make probable a much lesser, even negligible HAZ (heat influenced zone) about The situation of beam impingement.
The magnitude of the efficient nonlinear coefficient relies on the nonlinear tensor factors and to the utilized phase-matching website configuration. A high nonlinearity is important particularly In case the achievable optical intensities are reduced.
) to blow off dust along with other unfastened contaminants initially. If a dry nitrogen line is offered within the lab, an air gun can even be utilized to blow away dust particles. Blow from the area gently. Usually do not blow from the crystal itself out of your hand!
By analyzing the emitted gentle, the luminescent Attributes and defects on the crystal is often determined.
