The GHOST laser is a 67 TW OPCPA/Nd:glass laser system, delivering 10 J of laser energy in a 150 fs pulse with a center wavelength of 1057 nm. It uses a chirped pulse and an optical parametric amplification (OPA) frontend to broaden the spectral bandwidth to 30 nm before further amplification in a combination of silicate and phosphate glass laser gain media. The mixed glass architecture results in a broader spectral bandwidth and shorter pulse duration than a single type of glass. Focused with an f/3 optic, the GHOST laser can achieve intensities of up to 10^20 W/cm^2 in single shot mode or with a repetition rate of one shot per minute.
