HarmoniXX SHG
Second Harmonic Generation – Frequency Doubling for Tunable and Fixed Frequency Laser
Second Harmonic Generation
Nonlinear frequency conversion in SHG crystals makes it possible to generate new shorter wavelengths from existing laser wavelengths. As part of our HarmoniXX product line, the HarmoniXX SHG is a frequency converter for the frequency doubling of ultra short-pulse lasers. Second Harmonic Generation is a non-linear process, in which photons with the same frequency interacting with a non-linear material are effectively combined to generate new photons with twice the energy, and therefore twice the frequency and half the wavelength of the initial photons.
User-friendly Design
The focus is on user-friendliness and a compact design. By featuring a quick exchange of optics, the HarmoniXX Second Harmonic Generation device can be used for a wide pulse duration range, from femtoseconds (fs) to several picoseconds (ps).
