A: Sure, BBO crystals show remarkable thermal stability, creating them suited to applications with varying temperatures.
With correct care and routine maintenance, BBO crystals can previous for quite some time. Regular cleansing and suitable storage can help extend the lifespan from the crystals. Additionally, using the crystals inside of their specified working parameters also can help avert premature degradation.
In the event the Rayleigh range is below the crystal thickness, the gap around which the beam is optimally intense is less than the crystal thickness.
The Z-axis is parallel on the optical axis in the crystal as well as is Also called the terrific axis. The X- and Y-axes are parallel towards the optical axis and therefore are identified as frequent axes.
2nd harmonic technology (SHG): We benefit from SHG to evaluate our items�?nonlinear conversion efficiency and phase-matching angle to get a specified input wavelength. We assure that our merchandise fulfil the requirements for SHG applications.
A common technique for obtaining ultrathin crystals is always to very first optically Speak to a thicker nonlinear crystal with a few substrate (e.g. of fused silica) after which you can to shine the crystal down to the needed thickness of e.
Temperature amount sensitivity: BBO crystals temperature sensitivity has an effect on their refractive indices and likewise stage-matching complications. This demands temperature stage stabilizing or tuning tools to keep the best possible performance.
Figure 15 reveals the orientation of γ inside of a laboratory body rotation on the crystal. In this instance circumstance, the nonlinear crystal is mounted in an RSP1 rotation mount in addition to an RP01 rotation stage. Improvements in γ and θ adjust the orientation on the optic axis, . In this instance, adjustments in γ are already accustomed to align With all the horizontal airplane and one of many basic principle regular axes vertically. For just a vertically polarized input beam, this orientation permits the rotation stage to be used to regulate θ.
Employing our promoting package deal, you can Show your symbol, even more under your product description, and these will been found by lots of photonics industry experts.
For CPM, we Minimize our items at an angle equivalent to no or ninety levels stressing among the main axes. For NCPM, we reduced our merchandise at get more info an angle based on Snell’s regulation:
NCPM happens when the input beam propagates at an angle besides zero or ninety levels stressing one of many big axes, including the Z-axis. Its polarization is parallel to that axis, such as Z-polarized.
They also have a higher damage threshold, allowing for them to handle high-ability laser beams without degradation. These one of a kind Homes make BBO crystals a versatile Resource in several optical programs.
When an input pulse's spectral array is equal to or narrower as opposed to reference pulse, the created second harmonic pulse includes a length that is definitely shorter by an element of one/√two as well as a spectral width that is broader by a factor of √2.
This decreases the productive conversation dimensions and likewise lowers the conversion effectiveness. Such as, BBO crystals have an angular walk-off of concerning 38 mrad for SHG at 1064 nm wavelength, which has to try and do with 6 situations larger than KDP crystals.
