Summary form only given. In order to bring chirped pulse amplification (CPA) to its limit several issues still need to be solved. Among them is a reliable way of fighting gain narrowing in the amplifiers. We show here that a birefringent filter can compensate for gain narrowing in typical regenerative amplifiers. This set up is used to amplify sub-20 fs pulses to the millijoule level.
