Abstract :
Characteristics of storage ring free electron laser at a short wavelength region (UV and visible) has been studied at the UVSOR facility, Okazaki. We have introduced an empirical formula to describe the gain variation based on the bunch-heating model for gain-switched laser macropulses. Considerable substructures were found in both temporal distributions and frequency spectra. There are a couple of peaks discretely located in a laser optical bunch. Such an internal substructure has been found to be established in an early stage of lasing process.
