Brand: Coherent | Category: Nanotechnology
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 HGS is the harmonic generation accessory for Coherent's ultrafast amplifiers. It creates both second (SHG) and third (THG) harmonics, with the fourth harmonic (FHG) available as an option. Astrella is named as the amplifier it works with, and the listed applications are pump-probe spectroscopy and FSRS.
Coherent supply standard and custom beam delivery optics and optomechanical modules for excimer laser work, matched to the combination of high pulse energy, short UV wavelengths and high power. The range is grouped into attenuators, homogenisers and projection lenses, covering projecting, homogenising and attenuating the beam. The variable attenuator carries a compensator plate so that beam walk-off is eliminated.
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.
