Frequency Doublers - Triplers - Quadruplers

Rondo, the resonant harmonic converter, is the solution to cover spectral regions otherwise difficult to access via direct laser emission. It combines ultimate performances in a solid, simple-to-use and modular package.


Rondo can be employed in a variety of configurations to deliver the second, the third and the fourth harmonic of the fundamental laser.


Based on the Hänsch–Couillaud locking, Rondo doesn’t need phase modulation of the fundamental light, hence preserving the spectral purity.
