Hygroscopic crystal resources deteriorate when they are not often saved in sufficiently dry air (or simply a dry purge gasoline). This is applicable e.g. to KDP and BBO, As well as in a lesser extent to LBO. It may be practical to keep this type of crystal at a considerably elevated temperature, that makes it easier to retain it dry.
If the crystal surfaces are still “soiled�?immediately after the above mentioned cleansing strategies, the surfaces might have been damaged. Please Get in touch with us for rework in the crystals.
Most of the conventional nonlinear crystals like BBO, LBO, BiBO or KTP for frequency doubling, tripling and quadrupling of the fundamental laser radiation can be obtained from inventory. Consumer-precise Proportions and AR coatings can also be presented at competitive charges.
Typically, the crystal content must have a significant optical transparency for all wavelengths involved �?by way of example, for pump, sign and idler within an optical parametric amplifier.
BIBO crystals can be used as large-performance frequency doubling and frequency summing devices and also have broad application prospective buyers in optical parametric oscillation (OPO).
Remember to use "Insert to Cart" to put the exciting goods in the purchasing cart. Take a look at with on-line payment or check with us for the prices/availability by means of the browsing cart.
At the moment, as A form of excellent nonlinear second harmonic crystal, it can be used to create significant performance crystal of environmentally friendly or blue laser.
Crylink can be an open platform, just as our mission is to attach price, Crylink thinks that every individual and every business has unique worth, and we hope to connect with valuable you to provide value and mirror benefit with each other.
Although the nonlinear coefficient of KTP crystal is significant, the laser destruction threshold is very low, which is able to lead to difficulties including refractive index adjust and transmission loss. BIBO crystal has bigger laser destruction threshold and higher second harmonic conversion effectiveness. While LBO and B-BBO are the most useful, They are really modest in dimension and possess particular hygroscopicity, while BIBO crystals are non-wet and might improve to big measurement. These rewards help BIBO crystals for being widely applied.
Crystals which are non-critically phase-matched within a crystal oven may possibly show troubles when the crystal temperature is altered far too promptly or far too typically. Specifically, anti-reflection coatings could possibly be broken on account of distinctive thermal enlargement coefficients from the included resources.
) to blow off dust together with other loose contaminants initial. If a dry nitrogen line is obtainable inside the lab, an air gun can be employed to blow absent dust particles. Blow from the surface area Carefully. Never blow from the crystal itself from a hand!
GWU-Lasertechnik presents all regular nonlinear crystals like LBO, BBO and KTP that has a broad assortment of technical specs. Beside the effectively-proven components, innovative crystals like CLBO or BiBO with excellent Homes for e. g. deep-UV generation or high-electrical power ultrashort pulse lasers are offered. Irrespective of if particular person parts for R & D purposes are expected or Value-efficient more info figures in smaller, medium or significant batches with in-time supply for the manufacturing line are required: GWU’s devoted provider helps you to find the very best Main factors for the application.
The Coating curves, transmittance curves, flatness studies and floor quality report beneath microscope for BiBO Crystal will be delivered when delivered.
Large Problems Threshold: BIBO crystal contains a superior destruction threshold, allowing it to face up to higher laser electrical power without the need of suffering harm. This attribute will make BIBO suited to use in high-electricity laser systems.
