Ultrafast Systems offers second (SH) and third (TH) harmonics generators designed to work with a femtosecond Ti-Sapphire oscillator or an amplified laser output near 800 nm. Two BBO crystals (type I) are utilized to produce SH and TH outputs with high efficiency. The harmonics generator unit has dedicated outputs corresponding to ~267 nm, ~400 nm, and ~800 nm. These different outputs are easily directed into each of our Ultrafast Spectrometers to provide highly stable excitation sources.
