The BELLA Center is equipped with state of the art femtosecond laser systems based on the chirped pulse amplification (CPA) technique. There are three main systems: the BELLA Laser at petawatt peak power; TREX at 100-terawatt-class peak power; and Godzilla/Chihuahua, a set of 10-terawatt-class peak-power lasers. Each uses Ti:sapphire amplifier media pumped by frequency-doubled Nd:YAG pump lasers, achieving ~40 fs pulse lengths to resonantly drive LPAs. Associated beam lines are equipped for studies including LPA-based free-electron lasers, staging of multiple LPAs as a way to achieve higher energy or for beam disposal, and controlled particle injection and laser guiding.
