Frequency Converted Diode Lasers
Nonlinear frequency conversion techniques access wavelengths that cannot be generated directly with currently available laser diode technology. Via second or forth harmonic generation, these systems provide laser radiation in the UV, blue, green, yellow and orange spectral range. TOPTICA offers tunable, single-frequency systems at virtually any wavelength between 205 nm and 780 nm, employing ultrastable seed lasers, power amplification in semiconductor or fiber amplifiers, and a proprietary bow-tie cavity design – all in established pro technology.
TOPTICA’s Frequency Converted Systems include:
- Stand-alone Second Harmonic Genarator Module
- Tunable Frequency-Doubled Diode Lasers
- Tunable Frequency-Quadrupled Diode Lasers
