研究目的
Investigating the beam shaping capabilities of deformable mirrors for high power laser applications.
研究成果
Membrane mirrors show very good results for shaping round distributions but struggle with square distributions. Piezoelectric deformable mirrors show better results for both round and square distributions when a sufficient number of actuators is used. Future work will validate the results within experimental setups.
研究不足
The assumptions made in the model are often very simple, and cross-effects between actuators can usually not be ignored. More accurate models based on finite element methods are computationally extensive.
1：Experimental Design and Method Selection:
The study uses a model based on influence functions to investigate the beam shaping capabilities of deformable mirrors.
2：Sample Selection and Data Sources:
Several deformable mirrors from Flexible Optical B.V. are considered, focusing on membrane and piezoelectric types with varying numbers of actuators.
3：List of Experimental Equipment and Materials:
Deformable mirrors (MMDM and PDM types), optical design software Zemax OpticStudio.
4：Experimental Procedures and Operational Workflow:
The mirrors are integrated into Zemax OpticStudio via a dynamic-link library (DLL) for simulation and analysis.
5：Data Analysis Methods:
The normalized RMS deviation from the ideal intensity distribution is calculated to evaluate the beam shaping results.
