Abstract In the current work the method of radiation trapping treatment infinite coaxial cylinders using spherical coordinates is introduced. The operator of resonant transition process is obtained explicitly in the matrix form and its response to delta-function is analyzed in both hollow and solid cylinders. The influence of radiation trapping effect is shown on the example of model of miniaturized non-thermal atmospheric pressure plasma jet. The results of the calculations with the developed matrix method are compared to those based on the effective probability approximation. It is shown that the use of matrix method leads to significant spatial redistribution of the excited plasma species due to the non-local effects of radiation transport mechanism.

The continuous phase plate (CPP) is the vital diffractive optical element involved in laser beam shaping and smoothing in high-power laser systems. The high gradients, small spatial periods, and complex features make it difficult to achieve high accuracy when manufacturing such systems. A high-accuracy and high-efficiency surface topography manufacturing method for CPP is presented in this paper. The atmospheric pressure plasma jet (APPJ) system is presented and the removal characteristics are studied to obtain the optimal processing parameters. An optimized iterative algorithm based on the dwell point matrix and a fast Fourier transform (FFT) is proposed to improve the accuracy and efficiency in the dwell time calculation process. A 120 mm × 120 mm CPP surface topography with a 1326.2 nm peak-to-valley (PV) value is fabricated with four iteration steps after approximately 1.6 h of plasma processing. The residual figure error between the prescribed surface topography and plasma-processed surface topography is 28.08 nm root mean square (RMS). The far-field distribution characteristic of the plasma-fabricated surface is analyzed, for which the energy radius deviation is 11 μm at 90% encircled energy. The experimental results demonstrates the potential of the APPJ approach for the manufacturing of complex surface topographies.
