Parabola Focus Shows Strange Effects: A Deep Dive into Lasy and Axiprop

When working with parabolic optics, understanding the behavior of focal profiles is crucial for accurate calculations. However, issues can arise when using certain libraries, such as lasy and axiprop, to calculate these profiles. In this article, we will delve into the strange effects observed when using these libraries to calculate focal profiles for short focal lengths, and explore possible causes and solutions.

The Issue with Lasy and Axiprop

The issue at hand involves using lasy and axiprop to calculate known focal profiles for short focal lengths, which are still well above the paraxial limit. The results obtained show weird effects on the side of the focus to the lens, which worsen when the resolution of the grid is decreased. Conversely, increasing the resolution of the grid does not eliminate these effects. This has led to a search for guidelines on grid specifications required for axiprop, but none have been found.

Grid Specifications and Resolution

The grid specifications used in axiprop are crucial for accurate calculations. However, the lack of clear guidelines on grid specifications has led to experimentation with different grid resolutions. The goal is to resolve the spatial profile without taking an excessive amount of time to run the calculations. This has resulted in the use of grids that make sense, but may not be optimal for axiprop.

Comparison with Analytic Theory and Diffraction Integral

To better understand the issue, a comparison was made with the analytic theory and an alternative diffraction integral. The results obtained from these methods show no signs of the weird effects observed when using lasy and axiprop. This suggests that the issue may not be with the definition of the lens in lasy, but rather with the grids or method used in axiprop.

The Role of Grid Resolution

The grid resolution used in axiprop has a significant impact on the accuracy of the calculations. Decreasing the grid resolution can lead to a loss of detail in the spatial profile, resulting in the weird effects observed. Conversely, increasing the grid resolution does not eliminate these effects, suggesting that the issue may be with the method used in axiprop rather than the grid resolution.

The Importance of Grid Specifications

The grid specifications used in axiprop are critical for accurate calculations. However, the lack of clear guidelines on grid specifications has led to experimentation and trial-and-error approaches. This can result in suboptimal grid specifications, leading to inaccurate calculations and weird effects.

The strange effects observed when using lasy and axiprop to calculate focal profiles for short focal lengths are a complex issue. While the grid resolution used in axiprop has a significant impact on the accuracy of the calculations, the lack of clear guidelines on grid specifications has led to experimentation and trial-and-error approaches. The comparison with analytic theory and diffraction integral suggests that the issue may not be with the definition of the lens in lasy, but rather with the grids or method used in axiprop. Further investigation is needed to determine the root cause of the issue and to develop clear guidelines on grid specifications for axiprop.

Based on the findings of this article, the following recommendations are made:

Further investigation is needed to determine the root cause of the issue and to develop clear guidelines on grid specifications for axiprop.
The use of analytic theory and diffraction integral methods should be explored as alternative approaches to calculating focal profiles.
The grid specifications used in axiprop should be optimized to ensure accurate calculations and to eliminate weird effects.

Future work should focus on developing clear guidelines on grid specifications for axiprop. This will involve experimentation and testing of different grid resolutions and specifications to determine the optimal approach. Additionally, the use of analytic theory and diffraction integral methods should be explored as alternative approaches to calculating focal profiles.

The bottom left of the figure shows a 'close to paraxial limit' calculation case where the calculation completely fails. The bottom right plots what the focus looks like based on a correct calculation from the analytic theory and an alternative diffraction integral. As can be seen, these effects are not present.
