Gaussian-to-Top Hat Converters (g2T®)

Homogeneous top hat profiles offer key benefits with many applications (e.g. structuring of trenches in the material treatment) as compared with Gaussian beams (single-mode laser):

• Higher processing velocity
• Homogeneous ablation
• Lesser defects (cleaner interfaces)
• Steeper and smoother edges
• Smaller heat affected zone
• Lower cost per unit

LIMO's g2T®-converters can effectively be used in the Photovoltaics (PV), semiconductor and Flat Panel Display (FPD) industry - e.g. in P1, P2 and P3 processes for thin film solar cells.

The refractive g2T®-converter generates homogeneous Flat top profiles with high transmission. We keep for sale: standard solutions for all typical single-mode lasers with M² < 1,4 at 355, 532 and 1064 nm.
