An energy-recovery linac (ERL) for a high-power free-electron laser (FEL) is under development in JAERI. We completed the construction of the ERL, and demonstrated the first energy-recover operation and FEL lasing in 2002. For realizing FEL lasing in 5-10kW average power, further upgrade of the ERL is carrying on, which includes reinforcement of the injector, replacement of the RF control system and so on. As future plans, we present possible quantum control of chemical reaction dynamics through a self-chirped FEL pulse, application of ERL technologies to high-flux photon sources in a wide range of photon energy from THz radiation to -ray.
