"Progress toward rep-rated Multi-Petawatt Lasers"


Dr. Todd Ditmire
University of Texas at Austin

ABSTRACT 

In 2008 operation of the Texas Petawatt Laser to the power of 1.1 Petawatt (1015 W) was demonstrated. At that time it was the world's highest laser power output. The pulse contained 186 J of energy and was only 167 fs in duration. The laser is based on optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass amplification. The Texas Petawatt Laser produces a peak output nearly 2,000 times greater than the capacity of the entire U.S. electrical grid. With this intensely focused beam, a scientists produce the sort of dense matter found at the center of stars and recreates conditions characteristic of planetary cores. They observe the blast waves of scale supernovae and chart how such forces form galaxies in their wake.

Todd Ditmire is directs the Texas Center for High Energy Density Science. He presently works on experimental studies of high intensity laser interactions with matter. These interests include studies of intense laser pulse interactions with atomic clusters, the study of hot, dense plasma properties, and the laboratory simulation of astrophysical phenomena. Prof. Ditmire also has interest in experimental study of intense femtosecond x-ray pulse and neutron generation and interaction with matter. His research involves the development of ultra-high peak power lasers, which includes building the the Texas Petawatt laser at UT and his current project to build the 10 PW laser for th ELI project in the Czech Republic. The Texas Petawatt laser is presently the highest power laser in the US and one of the largest university laser science projects nationwide.
