RESUMEN
The design of high-repetition, high-average power, multipass amplifiers in which the pump power induced thermal lensing within the amplifier is used to create an equivalent lens waveguide for the production of diffraction-limited beams is analyzed.

RESUMEN
We have developed efficient multipass Ti:sapphire amplifiers for femtosecond chirped-pulse amplification. With only two of these devices we get an amplification factor of 10(8), which corresponds to a peak power of ~0.5 TW after compression. We present a detailed analysis of such a system and its advantages in terms of its high quantum yield (0.3), flexibility, optical quality, and potential for tunability.
