If you don't locate the suited goods earlier mentioned, you could possibly let's know your prerequisites or purposes in the shape below. Our revenue or specialized workers will get back to you immediately.

Laser processing and product dealing with: In the sector of laser processing and product managing, the superior electricity capacity of BIBO crystals tends to make them a critical ingredient inside the manufacture of superior Power density laser beams.

With a substantial helpful nonlinear coefficient, high injury threshold, and inertness to dampness, BIBO crystal delivers a number of strengths above other nonlinear optical resources for instance LBO and BBO.

Artifex Engineering provides finished crystal optics for non-linear applications. Go to our products web site To learn more. We anticipate your inquiry.

Even when the crystal material or coating is not really sensitive to water, compact drinking water droplets could focus laser radiation additional tightly than below ordinary operation, and so hurt the crystal material.

Note that even if the nominal depth is beneath the nominal destruction threshold, there may be problems as a consequence of fluctuations from the beam power or nearby depth (e.g., if a beam profile has “very hot spots�?, or resulting from isolated defects in the crystal, which happen to be extra delicate as opposed to normal crystal material.

Bismuth Triborate (BiB3O6 or BIBO) is often a freshly made nonlinear optical crystal. It possesses substantial efficient nonlinear coefficient, large destruction threshold and inertness with respect to humidity.

In the case of ultrashort pulses the substantial group velocity mismatch enforces the usage of a shorter crystal, which calls for substantial optical intensities for the provided conversion performance.

Many different Houses of a nonlinear crystal is often crucial for an software e.g. in nonlinear frequency conversion:

In lots of instances, a nonlinear crystal used for nonlinear frequency conversion has an exceedingly very long life time, which can be lengthier than that of The complete laser process. The crystal content is essentially not modified throughout Procedure. On the other hand, a decreased crystal lifetime can manifest less than a variety of situations:

This combination helps make BIBO crystal exceptionally suited for harnessing the phenomenon of second harmonic generation click here (SHG) inside of sound-condition lasers and laser diodes.

The magnitude of the efficient nonlinear coefficient will depend on the nonlinear tensor elements and over the utilized phase-matching configuration. A substantial nonlinearity is very important especially if the achievable optical intensities are lower.

g. in the shape of “grey monitoring�? This kind of phenomena are particularly popular for Procedure with ultraviolet light. Notice that a gradual degradation may guide into fast catastrophic hurt by way of too much heat era.
