A Petawatt laser based on hybrid optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass has been demonstrated. This concept enables peak powers which can be scaled significantly beyond one petawatt. Higher power lasers enable access to unprecedented scientific research in the studies of high intensity physics. In this paper we discuss the laser, the potential of scaling to higher...
We report on the activation of the 1.1 Petawatt Laser (190 J, 170 fs) based on optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass amplification.
A free space contra-propagation set-up is implemented and a dynamic pump-probe study of the eigenmodes of a SOA in the picosecond regime is undertaken. The time-resolved probe transmission of the TE and TM modes of the device is measured for the co and cross-polarised cases as a function of pump pulse energy. The relative contributions of interband and intraband processes to the gain compression are...
We present results in a comprehensive analysis of gain shaping from Nd:glass amplifiers in an effort to generate near 100 fs pulses in chirped pulse amplification. We discuss relative gain balance between the two media.
