They can be employed for frequency doubling invisible one-micron light-weight into 532nm obvious eco-friendly light-weight, an application that has Beforehand belonged to KTP crystals.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are supplies with a comparatively robust nonlinearity. They are frequently employed for nonlinear frequency conversion and also for electro-optic modulators. The two materials can be found in congruent As well as in stoichiometric sort, with important variations concerning periodic poling and photorefractive effects (see beneath). Lithium niobate and tantalate are definitely the most often made use of resources in the context of periodic poling; the ensuing products are known as PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT for your stoichiometric variations.
Hygroscopic crystal products deteriorate when they are not usually stored in sufficiently dry air (or possibly a dry purge gasoline). This applies e.g. to KDP and BBO, As well as in a lesser extent to LBO. It could be helpful to maintain this type of crystal at a considerably elevated temperature, that makes it simpler to maintain it dry.
The flux system allows for the creation of huge LBO crystals with very low defect density and high optical top quality. The usage of a flux can help to cut back impurities and defects inside the crystal, leading to improved crystal high quality.
5 mm to attenuate team velocity mismatch and are perfect for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The essential and noncritical section matching LBO crystals are ideal for 2nd or 3rd harmonic generation of Nd:YAG and Yb:doped lasers.
Optical parametric oscillation (OPO) is actually a nonlinear method that involves the conversion of the large-energy photon into two decrease-Power photons inside of a resonant cavity. LBO nonlinear crystals Possess a significant nonlinear coefficient, that makes them ideal for effective OPO.
Crystals for NCPM at an elavated temperature is usually premounted within an oven with precision controller. Crystals utilised at ~ 20 - 50 oC can even be premounted in a very compatible h2o-cooled or TEC (ThermoElectric Cooler) cooled mount upon ask for.
These problems, nonetheless, aren’t established in stone and largely depend upon the supposed application of your crystal along with the intricacies of the laser technique style. Commonly, when it comes to temperature,
Our crystals are Employed in an array of apps, like a variety of types of nonlinear frequency conversion and electro-optics, but will also quantum engineering.
The producing technique of LBO Crystals is really a testomony for the heights of scientific innovation. The Flux strategy, the cornerstone of LBO Crystal production, is often a meticulous approach involving a exact blend of raw supplies, exacting temperature Handle, and thoroughly managed chemical environments.
LBO is phase matchable for the SHG and THG of Nd:YAG and Nd:YLF lasers, working with possibly type I or kind II interaction. For your SHG at room temperature, type I section matching may be reached and has the utmost effective SHG coefficient inside the principal XY and XZ planes in a large wavelength vary from 551 nm to about 3000 nm.
In spectroscopy, OPO is utilized to produce tunable gentle resources for many applications, like chemical Assessment and material characterization. In metrology, OPO is used to produce frequency combs for exact frequency measurements.
SHG measurement can be applied to find out the crystal excellent and defects, for instance area structure and non-uniformity.
They can endure significant heat with no important general performance reduction, making sure that the optical procedure stays reputable and successful even LBO Crystal in demanding situations.
