Frequency-Converted Lasers

Frequency doubling and frequency quadrupling

Nonlinear frequency conversion techniques access wavelengths that cannot be generated directly from laser diode technology. Via second or fourth harmonic generation, TOPTICA laser systems can access the UV, blue, green, yellow and orange spectral ranges at high powers. TOPTICA offers tunable, single-frequency systems at any wavelength between 190 nm and 4000 nm, employing ultrastable seed lasers, power amplification in semiconductor or fiber amplifiers, and a proprietary bow-tie cavity design – all in established pro technology.
