APPLICATIONS

• Frequency converter for laser source (Nd:Yag, fiber laser…)
• Beam splitter and converter
• Tattoo removal (additional wavelengths)
• Beamer / laser display
• Spectrocopy (source), detection of pollutants

ADVANTAGES

• Based on standard optical dyes: can be tuned to any available wavelengths (UVVisible-NIR)
• Curable polymer : can be efficiently shaped (with parallel curing process) to any size and shape from a few μm to a few cm or deposited on flexible films, fiber end…
• Low cost manufacturing processes widely used in the semiconductor industry
• Low cost material: around 0.1€/cm²
• No need for optical resonator

DEVELOPMENT STATUS

• Characterization of medium with laser source Nd:YAG and about 20 different dyes from UV-visible and IR emission
• 18-months project funding for a proof-of-concept
