스펙 설명

Beamara presents variable laser beam expander for high power lasers. It features three main advantages that help to stand out from the competition:

·         Diffraction limited performance for ≥Ø6 mm beam in whole expansion range even at λ=343 nm

·         Ability to sustain high laser beam energy, therefore extend laser system uptime.

·         Collimation is maintained during expansion adjustment.

Variable expander features x1 to x4 range, that can be continuously zoomed along the range. Product is available for 1-st, 2-nd & 3-rd harmonics of both Neodymium and Ytterbium laser lines. Divergence adjustment solution is embedded in the system to allow for smooth and fine divergence adjustment compensation, which is crucial in laser machining process fine-tuning.

Expander is designed to comply strict stability, longevity, and robustness requirements that are inflicted by industrial lasers applications, which makes it suitable for both – industrial and demanding scientific use.

It is advised to consider high power beam expander design if average power exceeds the following values:

  • 1st harmonic >100W;

  • 2nd harmonic  >50W;

  • 3rd harmonic  >10W.
