Howdy, thanks for contacting Thorlabs. The wavelength ranges on the antireflective coatings on these β-BBO crystals align Along with the respective wavelength bands that these crystals are optimized for. Requests for customizations can be made by achieving out to us at [email protected]
When the Rayleigh vary is a lot less than the crystal thickness, the distance in excess of which the beam is optimally intense is under the crystal thickness.
The Z-axis is parallel on the optical axis from the crystal in addition to is Furthermore known as the wonderful axis. The X- and Y-axes are parallel to the optical axis and so are termed typical axes.
Second harmonic technology (SHG): We benefit from SHG to evaluate our goods�?nonlinear conversion performance and period-matching angle for your specified enter wavelength. We assurance that our goods fulfil the necessities for SHG apps.
The calculation earlier mentioned assumes a uniform beam intensity profile. You will need to now contemplate hotspots in the beam or other non-uniform intensity profiles and roughly work out a greatest ability density.
There are two velocities that define the propagation of sunshine in optical media: the phase and team velocities. The phase velocity would be the pace on the provider, the oscillation of the electric discipline, as well as the velocity which is matched involving the basic and second harmonic frequencies for stage matching. The stage velocity relative to your velocity of sunshine inside of a website vacuum is described from the index of refraction.
Presented these programs, it’s obvious why BBO, with its inherent ability to effectively deliver the 266nm wavelength, is so very prized. The crystal’s exceptional nonlinear optical Homes help the conversion of other wavelengths in to the coveted 266nm light-weight, ensuring that scientists and industries have use of this important Device.
Utilizing our promoting bundle, you'll be able to Screen your symbol, further under your solution description, and these will been witnessed by a lot of photonics specialists.
It’s like using a single Notice and splitting it into two harmonious tones. This process is often crucial in quite a few State-of-the-art optical experiments and systems.
NCPM occurs if the enter beam propagates at an angle apart from zero or 90 levels stressing one of several key axes, including the Z-axis. Its polarization is parallel to that axis, for instance Z-polarized.
What exactly are BBO Crystals? BBO crystals can be a form of nonlinear optical crystal recognized for their vast transparency variety, higher harm threshold, and excellent thermal and chemical steadiness.
The temporal stroll-off is frequently regarded severe once the temporal lag exceeds the duration of the elemental pulse. Extreme walk-off can lead to temporal lag that irreparably boosts the period in the output 2nd harmonic pulse.
This would make them hugely sturdy and resilient, additional enhancing their suitability for complicated optical programs.
