A: Certainly, BBO crystals exhibit extraordinary thermal security, making them well suited for applications with different temperatures.
Even though the above course of action gives a fantastic rule of thumb for LIDT values, please Get in touch with Tech Support When your wavelength is different from the specified LIDT wavelength. If the electricity density is lower than the adjusted LIDT of your optic, then the optic need to perform for your software.
A1: Sure, BBO crystals Have got a significant destruction threshold, producing them well suited for substantial-electrical power laser programs. Their ability to resist large laser intensities with no suffering from optical hurt would make them a superb choice for frequency conversion in large-electrical power lasers.
The elemental field now driving the Type-I SHG procedure is the Eoγ ingredient with the incident subject. At γ = 90°, there will be zero SHG output, Because the generate discipline Eoγ = 0.
For beams that has a substantial PRF each the common and peak powers have to be compared to the equal CW power. On top of that, for remarkably transparent supplies, There is certainly very little to no drop in the LIDT with expanding PRF.
BBO BBO Crystal crystals have two refractive indices: ne for remarkable rays and no for usual rays. The difference between ne and no is determined by the wavelength of light along with the crystal’s temperature.
When laser light is targeted to some location, the diameter on the beam waist is definitely the focal spot sizing, and the rate at which The sunshine diverges from your beam midsection is connected with the Rayleigh variety (zR).
The group velocity as well as the phase velocity usually are not equal, which means the sine wave in the provider and also the envelope of the heartbeat go through optical media at distinctive speeds.
We also layer our objects with anti-reflection layers to lessen illustration losses in the crystal surfaces.
For CPM, we Minimize our pieces at an angle equivalent to no or 90 levels stressing among the list of significant axes. For NCPM, we lessened our things at an angle based on Snell’s regulation:
At this sort of a specific wavelength, The sunshine possesses exceptional properties that are invaluable to certain Highly developed apps. Permit’s delve further into the necessity of this particular light-weight output.
They also have a superior destruction threshold, allowing for them to manage substantial-electrical power laser beams with out degradation. These unique Attributes make BBO crystals a versatile tool in many optical programs.
For that reason, the second harmonic pulse spectrum, shown on the proper, provides a spectral width somewhere around the same as The perfect case. Preferably, every single frequency in the fundamental pulse spectrum can be simultaneously phase matched.
Although the crystal material or coating isn't delicate to drinking water, smaller drinking water droplets may well concentration laser radiation additional tightly than underneath usual Procedure, and therefore hurt the crystal materials.
