Description
The shortening of the FEL pulse length is an important subject, and especially reducing the FEL pulse length down to a few-cycle duration is a great challenge. However, there exists a theoretical limit that disturbs the realization of few-cycle FELs, which is known as the slippage effect. Recently, the author proposed a novel idea to overcome this difficulty and experimentally demonstrated it [1]. This talk is expected to review its fundamental mechanism and report the results of the demonstration experiments, together with perspectives of few-cycle attosecond pulses that become available with this concept.
