Laser architecture

The APOLLON laser facility will combine on target, at a repetition rate of one shot per minute tir:

an ultra-intense utra-short main laser beam, “F1”, delivering 15 fs pulses of maximum energy 150 J, i.e. a peak power of 10 PW,
an intense ultra-short secondary laser pulse, “F2”, delivering 15 fs pulses of maximum energy 15 J, i.e. a peak power of 1 PW,
a creation beam, “F3”, delivering ns pulses of maximum energy  250 J,
a probe beam, “F4”, delivering 20 fs pulses of maximum energy 250 mJ (10 TW).

The expected detailed performances of the APOLLON laser system are given in the following table. These technical specifications have been established through discussion with the user community.

To meet this complete set of requirements in terms of contrast, bandwidth (duration) and energy, the APOLLON design is based on a hybrid OPCPA-Ti:Sapphire architecture, schematized below.
