We have completed the construction of a high peak power, ultrafast laser which delivers peak power in excess of 1 petawatt (1015 W). This laser, the Texas Petawatt Laser, is based on a combination of OPCPA and mixed Nd: glass amplifiers, enabling high energy operation with compressed pulse duration of <160 fs. The laser presently delivers 160 fs pulses with pulse energy exceeding 200 J. Using pulse shaping technology and broad band amplification on the front end, this laser demonstrates petawatt technology in Nd: glass amplifiers at pulse duration shorter than other Nd: glass-based petawatt facilities around the world. In my talk, I will report on the design and performance of the laser, including the technology used to access such high powers and near 100 fs compressed pulse duration…
