Abstract

We have developed a silver-mirror-based multipass preamplifier for a broadband amplification in a terawatt Ti:sapphire laser. With the extremely broad bandwidth of the silver mirrors, a very broad amplified spectrum can be generated at an amplified energy of 4mJ; the amplified spectral width is 65nm at half maximum and 160nm at 25dB without any spectral shaping technique. Such a broad amplification can be explained well by the simulation that includes gain narrowing and gain saturation. Even after a further amplification to an energy of 600mJ, the amplified spectrum is broad enough to support an 20fs transform-limited pulse duration.
