Article Synopsis
- A high power and quality picosecond laser is essential for MEMS fabrication, specifically in micromachines, necessitating optimal seed beam coupling for improved laser efficiency.
- The study identifies key physical parameters impacting coupling and establishes their relationships under optical mode matching conditions to achieve optimal results.
- Experimental validation shows a maximum transmittance of 87.2% with a 6 W input seed power, along with a diffraction-limited beam quality and high optical efficiency in further power amplification tests, confirming the theoretical findings.
