LBO Crystal - An Overview
Blog Article
LBO is an excellent NLO crystal for OPOs and OPAs that has a greatly tunable wavelength vary and large powers. The distinctive Attributes of type I and kind II phase matching as well as the NCPM leave an enormous space within the investigate and purposes of LBO's OPO and OPA.
LBO crystals with just one conclude or each finishes Minimize with the Brewster angle and uncoated are offered. This kind of crystals are frequently utilized to minimize the surface loss without the need of reduction in the hurt threshold by an AR coating for prime power programs.

XRD can even be employed to determine the crystal high-quality and defects while in the crystal, for example twinning and dislocations.
It is actually worthy of noting that the characterization strategies talked about In this particular chapter usually are not restricted to LBO nonlinear crystals and may be placed on other nonlinear crystals as well.
Optical parametric oscillation (OPO) is more info actually a nonlinear system that includes the conversion of the substantial-Electrical power photon into two decrease-energy photons within a resonant cavity. LBO nonlinear crystals Have got a significant nonlinear coefficient, which makes them perfect for productive OPO.
LBO crystal (Lithium triborate) is usually a non-linear optical product of option for frequency converting superior electricity lasers with its following primary options:
Even further enriching their optical charm is definitely the wide acceptance angle. This function allows for a lot more significant mild conversation and minimizes the requirements for beam alignment, simplifying the overall Procedure.
Dust and stains on crystal surfaces can result in scattering/reduction of sunshine and can even react with light-weight to break optical surfaces in a higher incident laser energy.
Past large power lasers, this thermal balance extends LBO Crystals�?applicability to some big selection of environments with various temperature situations.
When stacked up against other nonlinear optical crystals, LBO Crystals unmistakably maintain their floor. Their broad transparency array is a distinctive trait that surpasses most other crystals in the sector.
Numerous Homes of the nonlinear crystal can be important for an software e.g. in nonlinear frequency conversion:
LBO is usually a non-linear crystal. The importance of that is it may possibly alter the wavelength of the enter beam to a unique wavelength output. GAMDAN LBO has essentially no absorption in excess of a wide range of wavelengths, from a hundred and sixty to 2600 nanometers. Which means it is an excellent option for frequency tripling the emission of preferred just one-micron lasers in the UV, at all around 355 nanometers.
The knowledge of these techniques is important for the design and optimization of crystal expansion processes plus the production of significant-high quality LBO nonlinear crystals for several applications in optics and photonics.
