Gain narrowing and spectral shifting control in Apollon-10P, petawatt hybrid CPA laser system

Apollon-10P is a French funded 10 petawatt hybrid CPA laser system (OPCPA and titanium doped power amplifiers) that will be operating in 2013. The system will deliver pulses with energy of 150 joules in 15 fs pulse duration at 1 shot every minute. The OPCPA based front-end will deliver 30 mJ at 10 Hz with a spectrum having the availability to handle 10 – 15 fs pulses. The 1.5 ns stretched pulses will be further amplified up to 300 joules in Ti:Sa amplifiers. The choice of this hybrid solution has appeared to be the most efficient one in term of balance between ultra-short pulse duration and amplification efficiency and cost.
