SHG measurement is a frequently used technique for characterizing the nonlinear optical Qualities of LBO nonlinear crystals. SHG measurement includes shining a laser beam of a specific wavelength onto the crystal and measuring the intensity of the 2nd-harmonic wave created by the crystal.
It commences that has a perfectly-calibrated mix of lithium, boron, and oxygen within a crucible. This mixture is then subjected to a exactly managed thermal cycle, inducing the growth on the crystal.
We offer precision oven and temperature controller to keep up LBO crystals at a preset temperature for noncritical phasematching (NCPM) for SHG and OPO/OPA. Crystals could possibly be pre-mounted to the oven cost-free inside our manufacturing unit for your usefulness.
Raman spectroscopy can be employed to detect impurities and defects in LBO nonlinear crystals that can have an affect on their effectiveness in numerous programs. Raman spectroscopy can be applied to ascertain the crystal high-quality and stage purity.
The wonderful optical homogeneity and not enough inclusions in GAMDAN material imply excellent undistorted wavefront output from the system. LBO has an exceedingly high inside harm threshold as a result of its very low absorption. That residence also avoids beam distortion from thermal enlargement.
Operation of nonlinear crystals at temperatures under space temperature (to realize section matching) is usually problematic, as it could lead to condensation of drinking water about the crystal surfaces When the encompassing air will not be very dry.

GWU-Lasertechnik gives all common nonlinear crystals like LBO, BBO and KTP by using a broad selection of specifications. Beside the well-proven components, progressive crystals like CLBO or BiBO with outstanding Houses for e. g. deep-UV generation or significant-electrical power ultrashort pulse lasers are available. It does not matter if unique pieces for R & D reasons are demanded or Price-efficient numbers in tiny, medium or huge batches with in-time shipping to the creation line are wanted: GWU’s committed company helps you to discover the most effective Main elements for your personal application.
In lots of situations, a nonlinear crystal utilized for nonlinear frequency conversion has an incredibly long lifetime, which is longer than that of The complete laser technique. The crystal content is essentially not modified in the course of operation. Having said that, a diminished crystal lifetime can come about below many conditions:
Non-linear Optical (NLO) crystals present an enormously adaptable Remedy for building new wavelengths from current, off-the-shelf laser resources. The optical wavelength spectrum is used by a substantial and continually growing selection of apps, from producing of health care lasers, quantum networking & computing as a result of to environmental sensing along with quite a few others.
Inspect the crystal area for dust and stains by Keeping here it near a vibrant obvious-gentle source. Viewing at different angles can help see scattering from dust and stains. The crystal surface has to be cleaned as described below if dust and stains are uncovered.
Within the context of tension, LBO Crystals are usually used underneath ambient stress disorders in the majority of optical applications. They retain their structural integrity and optical Attributes below these ailments, ensuring reputable general performance.
) to blow off dust together with other unfastened contaminants to start with. If a dry nitrogen line is available inside the lab, an air gun can be employed to blow away dust particles. Blow from the surface Carefully. Do not blow from the crystal by itself out of your hand!
They exhibit very good homogeneity around significant volumes and have a large hurt threshold, but are hygroscopic and possess a small nonlinearity.
