When light from a femtosecond laser pulse is focused in a nonlinear crystal such as BBO or LBO, the strong nonlinear effects lead to the generation of photons at higher harmonics. Different optical setups allow for a number of higher harmonics, including second harmonic generation (SHG), third harmonic generation (THG) and fourth harmonic generation (FHG).

The second harmonic generation (SHG) unit, third harmonic generation (THG) unit, and fourth harmonic generation (FHG) unituse the Ti:sapphire fundamental wavelength to generate a wide range of secondary wavelengths.

Supercontinuum generation is a process where light with very broad spectral bandwidth and high spatial coherence is generated. Considerable spectral broadening of optical pulses can be acheived. Applications for supercontinuum generation include spectroscopy, imaging, physics and chemistry research, sensors, optical coherence tomography and telecommunication WDM sources.
