The external frequency conversion unit gives access to femtosecond laser emission in the visible (515 nm) and ultraviolet (343 nm). The unit comprises:

A second harmonic generator converts the infrared light emitted by the laser to a visible wavelength (515 nm), with a typical efficiency greater than 50%.
A Third Harmonic Generator converts the infrared light emitted by the laser to an ultraviolet wavelength (343 nm), with a typical efficiency on the order of 10 to 15%.
Wavelength separation by dichroïc mirrors.

The mechanical housing is placed at the output of the laser. Three outputs are available: Infrared, visible and ultraviolet.

	Second Harmonic	Third Harmonic
Conversion efficiency	> 50%	> 12%
Wavelength	515 nm	343 nm

Fourth harmonic generation (258 nm) is also possible. Please contact us for more information.
