Abstract

We implement, in the same femtosecond fiber amplifier setup, both chirped pulse amplification and divided pulse amplification. With the generation of temporally delayed replicas this scheme allows an equivalent stretched pulse duration of more than 1ns in a compact tabletop system. The generation of 45 W of compressed average power at 100 kHz, together with 320 fs and 450 μJ pulses, is demonstrated using a rod-type ytterbium-doped fiber.
