Although the above mentioned course of action supplies a good rule of thumb for LIDT values, be sure to Call Tech Guidance if your wavelength is different from the desired LIDT wavelength. If the ability density is less than the adjusted LIDT in the optic, then the optic need to get the job done for the software. 

However, it could be very difficult to check the LIDT specification of an optic to your laser. You will discover many regimes wherein a pulsed laser can harm an optic which is predicated over the laser's pulse length. The highlighted columns inside the table underneath outline the relevant pulse lengths for our specified LIDT values.

Be aware that although the nominal depth is down below the nominal hurt threshold, there might be challenges on account of fluctuations while in the beam power or area intensity (e.g., if a beam profile has “very hot places�?, or resulting from isolated defects inside a crystal, which happen to be far more sensitive in comparison to the common crystal substance.

Delving further into your prowess of BBO crystals, it’s apparent that they signify the forefront of modern photonics. Their wide transparency range not only bestows them with flexibility and also makes certain that they are suitable with varied gentle sources.

This kind of resilience makes certain that its nonlinear Attributes aren't very easily compromised, which makes it a favorite in environments exactly where consistency and dependability are paramount.

Now compare the utmost power density to that which happens to be specified as being the LIDT for that optic. When the optic was examined at a wavelength get more info apart from your running wavelength, the harm threshold should be scaled appropriately.

In conclusion, BBO crystals are an interesting and multipurpose substance which has significantly Sophisticated the sphere of optics and photonics. By knowledge their properties and the way to manage them, we can go on to harness their possible and generate more developments in optical technology.

In quasi-period matching, the crystal material is “poled�?to possess up and down domains to counteract the phase-mismatch of the material, exactly where the poling interval is precise for the wavelengths of interaction.

The next is usually a typical overview of how laser induced hurt thresholds are calculated And the way the values may very well be used in figuring out the appropriateness of an optic for the supplied software. When choosing optics, it is important to grasp the Laser Induced Injury Threshold (LIDT) of the optics being used. The LIDT for an optic enormously relies on the type of laser you will be making use of. Ongoing wave (CW) lasers usually result in problems from thermal effects (absorption possibly while in the coating or within the substrate).

Alternatively, a small enclosure (with openings for light-weight) may be constructed around the crystal using a ongoing flow of dry nitrogen of air into your enclosure. The dry nitrogen/air stress wants only to generally be somewhat higher than the ambiance to help keep the tiny quantity around the crystal dry and clean.

This can be the so-termed oo-e arrangement, as The 2 photons from the fundamental are polarization-oriented together the standard axis and the second harmonic photon's polarization is while in the incredible plane.

Optical parametric amplification (OPA): We use OPA to evaluate our parts�?nonlinear conversion performance and section-matching angle for any presented input wavelength and signal/idler wavelengths. We promise that our solutions fulfill the specs for OPA applications.
