The TSSG technique is a relatively new procedure that has gained attractiveness for its capability to produce higher-high-quality crystals with lower defect density.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are products with a relatively robust nonlinearity. They will often be used for nonlinear frequency conversion in addition to for electro-optic modulators. Both products can be found in congruent As well as in stoichiometric form, with vital differences regarding periodic poling and photorefractive outcomes (see down below). Lithium niobate and tantalate are the most frequently made use of materials in the context of periodic poling; the resulting materials are called PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric versions.
We provide precision oven and temperature controller to keep up LBO crystals in a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals may be pre-mounted in to the oven totally free in our manufacturing facility to your benefit.
Take note that even when the nominal intensity is beneath the nominal problems threshold, there may be issues as a result of fluctuations during the beam electrical power or area intensity (e.g., if a beam profile has “hot places�?, or on account of isolated defects within a crystal, that are a lot more sensitive than the regular crystal substance.
Lastly, once the crystal has grown to the specified dimensions, it can be harvested, Slice, polished, and coated determined by its intended software. This demanding and exacting procedure ends in an LBO Crystal that strikes a wonderful stability in between measurement and quality, manifesting the unbelievable optical properties that these crystals are celebrated for.
LBO crystal (lithium triborate) is One of the more applied nonlinear crystal for harmonics technology for short and very long pulse programs. As a consequence of it’s reasonably smaller walkoff angle long crystals may very well be employed what enables to obtain large conversion effectiveness.
Crystals for NCPM at an elavated temperature could be premounted within an oven with precision controller. Crystals applied at ~ twenty - fifty oC can also be premounted in a appropriate drinking water-cooled or TEC (ThermoElectric Cooler) cooled mount upon ask for.
No matter if it’s a minimal-temperature scientific experiment or simply a substantial-temperature industrial approach, it is possible to rely on LBO Crystals to deliver constant performance. Their means to take care of their nonlinear optical Qualities throughout a wide temperature range further more augments their versatility.
In the situation of ultrashort pulses the substantial group velocity mismatch enforces the usage of a shorter crystal, which demands large optical intensities for your offered conversion performance.
This chapter discusses website in detail the several crystal progress methods useful for the manufacture of LBO nonlinear crystals.
In addition to that, the substantial hurt threshold �?the power of LBO Crystals to resist significant-depth laser beams devoid of compromising their framework or general performance �?is usually a A great deal-appreciated high-quality, specifically in significant-electric power laser apps.
The magnitude of the powerful nonlinear coefficient is determined by the nonlinear tensor factors and within the used stage-matching configuration. A superior nonlinearity is vital particularly In case the achievable optical intensities are low.
This wide range empowers them to communicate with numerous laser sources, opening up a broad spectrum of purposes across a variety of scientific and industrial sectors.
Lithium Triborate (LBO) is not simply A different crystal; it’s a marvel of materials science that pushes the boundaries of nonlinear optics. A crystalline good with a singular composition of lithium, boron, and oxygen, LBO stands tall with its unmatched qualities.
