We report the construction of FEL transport line and the measurement method of chirped FEL pulse. An infrared-chirped pulse is an effective way of dissociating molecules. The chirped FEL pulse oscillator is operated by the JAERI-FEL superconducting accelerator, in which a long pulse of electron beam is produced. Until now, the chirped pulse was measured to be 
= 14.3% with the wavelength of 23.3 
m and the pulse width of 319 fs at FWHM by an autocorrelation. In order to measure the correlation between time and frequency in the chirped pulse directly, the frequency-resolved optical grating (FROG) is developing. Since the measurement is performed in new experimental room, the vacuum transport line guiding the FEL to the room has been constructed.

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.
