A regenerative amplifier system is used for pump-probe and other non-linear optical measurements. Micro-Joule pulses of less than 50 fs duration are generated at 800 nm wavelength. Visible and near-infrared optical parameteric amplifiers, a difference frequency generator, and various doubling units allow pulses to be generated with wavelength ranging from the ultraviolet to the infrared.
Spectrometers, beam profilers, autocorrelators, and a Spectral Phase Interferometry for Direct Electric-field Reconstruction (SPIDER) instrument are available for beam characterization. The seed oscillator is equipped with a synchrolock unit to facilitate phase locking to other instruments.
