Abstract
In this paper, a novel arrangement of multipass Ti:sapphire amplifier based on a parabolic mirror is demonstrated, by using disc-anvil structure. With a 532-nm pump power of 4.1 W, we got 340 mW amplified Gaussian beam centered at 800 nm when seeding 7 nJ 1 kHz pulses, and the efficiency reaches to 8.3%. Since it experiences less dispersion in this novel arrangement, it is much easier to get amplified ultrashort pulses shorter than sub-50-fs from CPA system consisted of this new type of multipass amplifier.
