In the Ti:Sapphire range and other bands, tightly toleranced partial reflectors are needed to split the beams or to couple out a certain proportion while keeping the GDD under control.
If not mentioned otherwise, all values and diagrams are given
... for the standard substrate material used in the described wavelength area (mostly Fused Silica or CaF2).
... without consideration of the rear surface.
... with EBE coating technique for a good cost-performance ratio.
Customized coatings are available for all types.
–––– dashed lines show the zoomed curve with the stated magnification
1020–1040 nm: R ±0.5% vs. curve; | GDD (R) | < 20 fs² (IBS-coating)
690–1050 nm: R ±0.25% (goal ±0.1%) vs. curve (IBS-coating)
Tolerance for transmission: ±0.2% absolute or ±10% of target value (IBS-coating)
Every coating type can be optimized
• substrate material
• angle of incidence
• GDD value
Alternatively we can create
a totally new design for you.
