Terahertz Generators and Detectors:
Electro-Optic DAST Crystals

DAST: 4-N,N-dimethylamino-4’-N’-methyl-stilbazolium tosylate

Example of an as-grown DAST crystal and organic crystals polished, coated and mounted for optical applications. DAST and other high-quality organic crystals are produced and optically prepared in the facilities of Rainbow Photonics in Switzerland.

Features

• High quality crystals
• Cut and polished for various applications
• Large nonlinear optical susceptibilities (d₁₁ > 1000 pm/V)
• Large electro-optic coefficients (r₁₁ = 92 pm/V)

Applications

• Efficient THz generation and detection
• Fast electro-optic modulation
• Optical parametric generation
• Efficient frequency doubling of 1.55 μm radiation
