| Research Abstract |
In order to generate a high-quality and high-current electron beam in an energy recovery linacs (ERL), a promising candidate of the next-generation light source, a laser system driving an electron gun of the ERL was developed based on a fiber laser, which was expected to be highly stable for high output power. A higher output power than the target value for the beam current of 10mA was achieved at the high-repetition rate of 1.3 GHz by a developed laser system. The system has been used for a test ERL facility at KEK, the Compact ERL and it demonstrated to stably work as the ERL drive laser. It is greatly expected to be applicable to electron guns of FELs as well as ERLs and various laser systems in accelerators.
