Hygroscopic crystal products deteriorate when they are not always saved in adequately dry air (or possibly a dry purge fuel). This applies e.g. to KDP and BBO, and in a lesser extent to LBO. It might be valuable to help keep such a crystal in a considerably elevated temperature, which makes it simpler to maintain it dry.
Laser processing and product managing: In the field of laser processing and material dealing with, the high electric power capability of BIBO crystals can make them a important part in the manufacture of substantial energy density laser beams.
Inspect the crystal floor for dust and stains by holding it close to a shiny visible-light-weight resource. Viewing at distinct angles can assist see scattering from dust and stains. The crystal area should be cleaned as described below if dust and stains are discovered.
Normally, the crystal material ought to have a superior optical transparency for all wavelengths concerned �?for instance, for pump, sign and idler within an optical parametric amplifier.
BIBO crystals can be utilized as superior-efficiency frequency doubling and frequency summing equipment and have wide software prospective clients in optical parametric oscillation (OPO).
GWU-Lasertechnik has over 30 yrs of expertise in distributing laser crystals. Pick out GWU to gain from our wide information As well as in-area practical experience!
Filters beneath or the form at the bottom may be used to aid merchandise search or make additional inquiries.
Procedure of nonlinear crystals at temperatures underneath area temperature (to achieve period matching) is generally problematic, as it could produce condensation of water within the crystal surfaces if the bordering air is just not extremely dry.
Even though the nonlinear coefficient of KTP crystal is big, the laser hurt threshold is low, which can bring about issues including refractive index improve and transmission decline. BIBO crystal has greater laser hurt threshold and better next harmonic click here conversion performance. Even though LBO and B-BBO are by far the most practical, They're tiny in measurement and possess certain hygroscopicity, whilst BIBO crystals are non-wet and may expand to massive measurement. These strengths help BIBO crystals to generally be greatly used.
Abnormal optical intensities through Procedure may possibly quickly injury a crystal. Sadly, nonlinear crystals frequently need to be operated not considerably from their optical problems threshold to accomplish a adequately substantial conversion efficiency. This suggests a trade-off involving conversion effectiveness and crystal lifetime.
Non-linear Optical (NLO) crystals give an enormously adaptable Alternative for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a sizable and regularly increasing assortment of apps, from production of professional medical lasers, quantum networking & computing through to environmental sensing in addition to numerous Other people.
GWU-Lasertechnik gives all common nonlinear crystals like LBO, BBO and KTP which has a wide variety of specs. Beside the properly-established components, modern crystals like CLBO or BiBO with remarkable Attributes for e. g. deep-UV technology or superior-power ultrashort pulse lasers are available. Irrespective of if person parts for R & D uses are demanded or Price tag-effective quantities in small, medium or large batches with in-time shipping with the manufacturing line are wanted: GWU’s devoted service helps you to locate the most effective core components in your software.
The Coating curves, transmittance curves, flatness experiences and surface good quality report under microscope for BiBO Crystal will be furnished when delivered.
g. in the form of “gray tracking�? These kinds of phenomena are specially popular for Procedure with ultraviolet light-weight. Take note that a gradual degradation may also direct into instantaneous catastrophic destruction by way of too much warmth era.
