High-extraction-efficiency operation of a midinfrared free electron laser enabled by dynamic cavity desynchronization

The extraction efficiency is one of the key parameters of an oscillator-type free electron laser (FEL). An extraction efficiency higher than 5% was observed with the midinfrared (MIR) FEL at Kyoto University using a dynamic cavity desynchronization method. The observed efficiency is the highest extr...
