Ultrashort quantum beam facility (UQBF) project in Advanced Photonics Research Institute (APRI), GIST aims to develop a 0.1-Hz petawatt Ti:sapphire laser system based on chirped pulse amplification. Currently, the average output energy of 46.3 J has been reached at 0.1-Hz repetition rate. The output energy of 46.3 J corresponds to 1.1 PW, considering the pulse duration of 30 fs and the grating efficiency of 69.3%, which have been measured with a single-shot SPIDER and a preliminary pulse compressor. UQBF construction is on schedule for the first petawatt experiments in 2010.

    We show that polymer distributed feedback lasers can be optically controlled at high bit-rate by using an ultrashort gate pulse.
