Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a relatively powerful nonlinearity. They will often be utilized for nonlinear frequency conversion in addition to for electro-optic modulators. The two materials are available in congruent and in stoichiometric sort, with vital differences concerning periodic poling and photorefractive effects (see below). Lithium niobate and tantalate will be the most frequently applied materials within the context of periodic poling; the ensuing elements are identified as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric variations.
Hygroscopic crystal materials deteriorate when they are not always held in sufficiently dry air (or simply a dry purge gas). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It could be practical to maintain such a crystal at a rather elevated temperature, that makes it simpler to keep it dry.
The quantity of the solvent is usually adjusted for many crystal dimension Therefore the lens tissue is retained moist for the whole drag but there's not any obvious trace of solvent on the crystal surface area following the drag is concluded. Inspect the floor and repeat if vital, but only use Each individual sheet of lens tissue at the time.
five mm to minimize team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The important and noncritical period matching LBO crystals are ideal for second or third harmonic generation of Nd:YAG and Yb:doped lasers.
LBO crystal (lithium triborate) is Probably the most made use of nonlinear crystal for harmonics technology for brief and extensive pulse purposes. Because of it’s reasonably modest walkoff angle extended crystals may very well be made use of what makes it possible for to accomplish substantial conversion efficiency.
LBO crystal (Lithium triborate) is often a non-linear optical product of option for frequency converting high energy lasers with its subsequent major characteristics:
These ailments, even so, aren’t established in stone and largely rely upon the intended application of the crystal plus the intricacies with the laser method style and design. Usually, concerning temperature,
Kind II NCPM OPO pumped by a XeCl excimer laser at 308nm has obtained 16.five% conversion performance, and moderate tunable wavelength ranges could be attained with various pumping sources and temperature tuning.
LBO Crystals have cemented their standing as an integral Element of the laser sector, contributing considerably to progress in laser technological innovation. With a high problems threshold and superb optical homogeneity, LBO Crystals can face up to the superior-intensity outputs which can be commonplace in significant-electric power laser techniques, proficiently enabling these units to perform optimally without having chance of harm to their components.
If you do not locate the ideal goods higher than, chances are you'll let us know your requirements or apps in the shape under. Our revenue or complex staff will get back again for you immediately.
The magnitude on the successful nonlinear coefficient is determined by the nonlinear tensor factors LBO Crystal and within the used period-matching configuration. A superior nonlinearity is vital specially In the event the achievable optical intensities are minimal.
This wide selection empowers them to connect with varied laser resources, opening up a wide spectrum of apps throughout various scientific and industrial sectors.
The comprehension of these methods is crucial for the design and optimization of crystal progress processes plus the production of significant-good quality LBO nonlinear crystals for numerous apps in optics and photonics.
