A fixed expansion ratio laser beam expander for high power applications, featuring four main advantages over the competition:
The fixed beam expander is available for 1st, 2nd, and 3rd harmonics of both Neodymium and Ytterbium laser lines. The divergence adjustment solution is embedded in the system to allow for smooth and fine divergence adjustment compensation, which is crucial in the laser machining process fine-tuning.
The expander is designed to comply with strict stability and robustness requirements that are imposed by industrial laser applications, making it suitable for both industrial and demanding scientific use. The hard locking function allows locking the lenses in place, making the beam expander resistant to high loads from acceleration and deceleration when it is mounted onto moving parts.
It is advised to consider a high power beam expander design if average power exceeds the following values:
1st harmonic: >100W
2nd harmonic: >50W
3rd harmonic: >10W
