If you don't find the appropriate products previously mentioned, you might allow us to know your necessities or purposes in the form down below. Our product sales or complex staff members will get back again for you as soon as possible.
In addition it has an important software in productive technology of ultrabright entangled photons via blue pumped spontaneous parametric down conversions (SPDC).
A lot of the conventional nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the basic laser radiation can be found from inventory. Customer-certain dimensions and AR coatings also are offered at competitive rates.
Crystal life time may also be strongly dependent on the fabric top quality, Whilst particular degradation phenomena seem like intrinsic constraints of the fabric.
Equally have a comparatively very low hurt threshold, but don't need to be operated at superior intensities because of their high nonlinearity. They may have a bent for photorefractive consequences, which might be harmful for frequency conversion, but are employed for, e.g., holographic information storage in Fe-doped LiNbO3 crystals. The inclination for “photorefractive destruction�?relies upon strongly on the material composition; e.g. it can be reduced via MgO doping and by making use of a stoichiometric composition.
Employing our promotion package, it is possible to Exhibit your brand, even further down below your product description, and these will been noticed by several photonics professionals.
Be aware that although the nominal intensity is under the nominal destruction threshold, there may be troubles due to fluctuations while in the beam power or neighborhood depth (e.g., if a beam profile has “scorching places�?, or due to isolated defects inside a crystal, which can be a lot more sensitive compared to normal crystal material.
Scientific analysis and enhancement: BIBO crystals also Engage in a crucial job in scientific investigate and advancement. Its excellent nonlinear optical general performance gives new resources and choices for ultrafast phenomenon investigation, powerful area physics, biomedical imaging and various fields
In the case of ultrashort pulses the high team velocity mismatch enforces using a shorter crystal, which necessitates higher optical intensities to get a offered conversion performance.
Excessive optical intensities throughout operation could immediately problems a crystal. However, nonlinear crystals frequently must be operated not much from their optical destruction threshold to realize a adequately higher conversion effectiveness. This suggests a trade-off involving conversion efficiency and crystal life time.
Bismuth Triborate (BiB3O6 or BIBO) is a recently made nonlinear optical crystal. It possesses big productive nonlinear coefficient, higher problems threshold and inertness with regard to humidity.
GWU-Lasertechnik features all normal nonlinear crystals like LBO, BBO and KTP with a broad variety of requirements. Beside the well-proven materials, modern crystals like CLBO or BiBO with outstanding Qualities for e. g. deep-UV generation or high-electrical power ultrashort pulse lasers can be obtained. No matter if person pieces for R & D functions are necessary or Charge-successful quantities in small, medium or huge batches with in-time shipping and delivery for your manufacturing line are necessary: GWU’s devoted services really helps to locate the finest core elements for the software.
linear absorption, which may trigger heating at significant optical energy stages, so that the period matching is disturbed, and thermal lensing may well take place
Higher Harm Threshold: more info BIBO crystal features a higher harm threshold, enabling it to resist higher laser energy without struggling hurt. This characteristic will make BIBO appropriate for use in higher-power laser devices.
