Coherent group the SHBC/TOPAS-400 with the tunable OPAs on their ultrafast amplifier accessories page. It creates narrow-band picosecond pulses tunable from 240 nm to 10 µm. Astrella is the amplifier it works with, and FSRS, pump-probe spectroscopy and SFG spectroscopy at surfaces are the applications given.
Coherent's harmonic generator sits among the accessories offered for their ultrafast oscillators. It creates second, third and fourth harmonics covering 190 to 540 nm. The page pairs it with the Chameleon and Vitara oscillators, and cites pump-probe spectroscopy and material sciences as the typical applications.
The SSA is listed as the autocorrelator accessory for Coherent's ultrafast amplifiers. Coherent describe it simply as a pulse width diagnostic tool. It works with Astrella, and pulse measurement is the stated application. No numerical data is published for it on the accessories page.
