This is our Ekspla System consisting of a picosecond Nd:YAG laser that is doubled and tripled in frequency and whose ultraviolet output pumps an optical parametric generator/amplifier system that ultimately delivers short (20 picosecond) optical pulses with a wavelength that can be tuned from 420 nm to 2 micrometer in the infrared. This system is used for various spectrally-resolved and time-resolved experiments.


The optical tables in the background hold the main laser system and various experimental setups, including degenerate four-wave mixing, a Maker-fringes experiment, and Z-scan.
