If you do not discover the suitable merchandise above, chances are you'll allow us to know your demands or apps in the shape below. Our product sales or complex staff members can get back again to you personally as quickly as possible.
In addition it has an important application in successful technology of ultrabright entangled photons by way of blue pumped spontaneous parametric down conversions (SPDC).
5 mm to attenuate team velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The vital and noncritical stage matching LBO crystals are ideal for next or 3rd harmonic technology of Nd:YAG and Yb:doped lasers.
With a substantial productive nonlinear coefficient, large hurt threshold, and inertness to humidity, BIBO crystal presents quite a few strengths about other nonlinear optical supplies for instance LBO and BBO.
Also, it may be extremely desirable to employ a crystal product that may be critically period-matched at area temperature since noncritical period matching usually entails the operation of the crystal in a very temperature-stabilized crystal oven. Nonetheless, the feasibility of significant stage matching may be supplied only for sufficiently high peak powers.
Dust and stains on crystal surfaces can cause scattering/decline of light and can even react with gentle to damage optical surfaces in a substantial incident laser electrical power.
Lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are components with a comparatively potent nonlinearity. They tend to be used for nonlinear frequency conversion and in addition for electro-optic modulators. Both equally products can be found in congruent As well as in stoichiometric variety, with important variations regarding periodic poling and photorefractive outcomes (see below). Lithium niobate and tantalate would be the most often used materials within the context of periodic poling; the resulting products are termed PPLN (periodically poled lithium niobate) and PPLT, respectively, or PPSLN and PPSLT with the stoichiometric variations.
Crylink can be an open up System, equally as our mission is to connect benefit, Crylink thinks that each particular person and each firm has unique value, and we hope to connect with beneficial you to deliver worth and mirror price collectively.
They exhibit superior homogeneity over massive volumes and possess a large destruction threshold, but are hygroscopic and have a very low nonlinearity.
Borates including LBO and BBO also function perfectly in broadly tunable optical parametric oscillators and optical parametric chirped-pulse amplification.
In many cases, a nonlinear crystal useful for nonlinear frequency conversion has an exceptionally prolonged lifetime, which is for a longer period than that of The full laser program. The crystal materials is actually not modified throughout Procedure. Even so, a decreased crystal life span can arise below many situation:
GWU-Lasertechnik delivers all conventional nonlinear crystals like LBO, BBO and KTP having a broad assortment of requirements. Beside the very well-recognized elements, progressive crystals like CLBO or BiBO with excellent Houses for e. g. deep-UV technology or significant-energy ultrashort pulse lasers are offered. It doesn't matter if unique items for R & D uses are needed or cost-productive figures in tiny, medium or huge batches with in-time shipping and delivery for your manufacturing line are required: GWU’s dedicated company really helps to discover the ideal core components for your personal application.
The Coating curves, transmittance curves, flatness reviews and area good quality report below microscope for BiBO Crystal are going to be presented when shipped.
Considering that the second harmonic (SHG) might be widely used here to deliver coherent seen gentle and ultraviolet radiation, persons listen to it, but the normal nonlinear crystals such as KDP, LBO, KTP, B-BBO even have many shortcomings. BIBO crystal is a brand new style of nonlinear crystal. As opposed with KDP crystal, it helps make up for your drawback that KDP crystal can grow in significant dimensions but dissolve in water.
