Femtosecond Amplifier and OPAs



A Spectra-Physics Tsunami pumped with a Spectra-Physics Beamlok Ar:Ion laser seeds a customized Spectra-Physics Spitfire two-stage amplifier pumped by two Spectra-Physics Merlins to produce ~2 mJ pulses of 800 nm/100 fs light at a repetition rate of 1 kHz. This light is directly available for intense field studies, or can be split into two 1 mJ pulse trains to pump two independent Spectra-Physics OPA-800 OPA systems capable of producing wavelengths from 10 mm to 200 nm. This affords the luxury of two-color experiments of any color combination and with any relative delay between the sources. In rare cases where some of the other colors produced as a by-product of the OPA process can be used, three- or many-color experiments are also possible.
