What will make LBO Distinctive is its mix of a large transparency variety, extending from the ultraviolet into the much infrared, and an exceptionally significant injury threshold.
You need to think about the wavelength and power within your laser supply and pick a crystal that may be transparent in the given wavelength and can face up to the laser energy. Lastly, other things including the thermal balance, optical homogeneity, and nonlinear optical coefficient from the crystal also must be deemed.
Filters underneath or the shape at The underside may be used to assist product or service lookup or make further inquiries.
Note that regardless of whether the nominal depth is underneath the nominal destruction threshold, there might be challenges because of fluctuations within the beam power or community intensity (e.g., if a beam profile has “scorching places�?, or as a consequence of isolated defects in a crystal, which are more delicate compared to typical crystal product.
Each have a comparatively lower destruction threshold, but will not have to be operated at high intensities because of their substantial nonlinearity. They've got an inclination for photorefractive outcomes, which can be harmful for frequency conversion, but are utilized for, e.g., holographic data storage in Fe-doped LiNbO3 crystals. The tendency for “photorefractive hurt�?relies upon strongly on the material composition; e.g. it can be minimized by way of MgO doping and by making use of a stoichiometric composition.
Optical parametric oscillation (OPO) is usually a nonlinear procedure that requires the conversion of a superior-Electricity photon into two decrease-Electrical power photons in a very resonant cavity. LBO nonlinear crystals Have a very higher nonlinear coefficient, that makes them ideal for economical OPO.
LBO crystal (Lithium triborate) is often a non-linear optical material of option for frequency converting large electrical power lasers with its pursuing main capabilities:
LBO Crystals exhibit substantial thermal steadiness and continue on to operate successfully over a wide temperature variety. This wide vary permits flexible method design and style and makes sure that the crystal overall performance is just not compromised, even underneath fluctuating temperature problems.
On top of that, LBO Crystals boast a sizable nonlinear coefficient. This trait is important in nonlinear optical procedures for example frequency doubling, the place it facilitates effective conversion from the incident gentle to a distinct frequency.
Non-linear Optical (NLO) crystals supply an enormously versatile Alternative for creating new wavelengths from present, off-the-shelf laser sources. The optical wavelength spectrum is used by a significant and constantly growing number of apps, from producing of health-related lasers, quantum networking & computing as a result LBO Crystal of to environmental sensing and also several Some others.
Inspect the crystal floor for dust and stains by Keeping it in the vicinity of a vibrant noticeable-gentle supply. Viewing at distinctive angles might help see scattering from dust and stains. The crystal surface area must be cleaned as explained underneath if dust and stains are discovered.
One of the more frequent applications is frequency doubling, in which LBO Crystals successfully transform the frequency of the high electrical power laser, effectively halving the wavelength and opening up a spectrum of prospects for laser programs.
For client convenience and defense of crystals, normal one" anodized aluminum (Al) mounts is usually presented on request. The mounted crystals can be even further mounted in a standard 1" mirror mount to be angle tuned for stage matching (
They can endure sizeable warmth with none significant efficiency reduction, guaranteeing that your optical technique stays reliable and productive even in demanding situations.
