Multiterawatt Ti:sapphire lasers in the 10-fs regime Academic Article uri icon

abstract

  • Efficiency and fidelity of chipped pulse amplifications are limited primarily by: (1) control of higher order phase distortion and (2) gain narrowing during amplification. In this work these problems with an organized quintic-phase-limited expander and compressor design and regenerative pulse shaping. In this paper, a three stage result amplification system that is designed to produce 1J pulses of -15 fs in duration. To date the first two stages of amplification have produced its 18 fs-, 4 TW pulses at a repetition rate of 50Tz and an average power of 4W. It is believed that these intermediate results represent the shortest terawatt pulses, the highest expansion ratio (100,000 times) and the highest average power yet produced by any chirped pulse amplification system.
