We are de­vel­op­ing an Yb fiber laser sys­tem that drives an ERL pho­to­cath­ode gun. An Yb fiber laser is ex­pect­ed to have both high sta­bil­i­ty and high out­put power re­quired for the drive laser of an ERL pho­to­cath­ode gun. First we start­ed to de­vel­op an Yb fiber laser os­cil­la­tor with a high rep­e­ti­tion rate up to 1.3 GHz that is the RF fre­quen­cy of a su­per­con­duct­ing ac­cel­er­at­ing cav­i­ty and then a 30W pream­pli­fi­er using an Yb doped pho­ton­ic crys­tal fiber. We re­port our re­cent progress in this de­vel­op­ment.

Fu­ture syn­chrotron light source using a 5-GeV-class en­er­gy re­cov­ery linac (ERL) is under pro­pos­al by our Japanese col­lab­o­ra­tion team, and we are con­duct­ing ac­tive R&D ef­forts for that. We are de­vel­op­ing su­per-bril­liant DC pho­to­cath­ode guns, two types of cry­omod­ules for both in­jec­tor and main su­per­con­duct­ing linacs, 1.3 GHz high CW-pow­er rf sources, and other im­por­tant com­po­nents. We are also con­struct­ing a com­pact ERL for demon­strat­ing the re­cir­cu­la­tion of low-emit­tance, high-cur­rent beams using those key com­po­nents. We pre­sent our re­cent progress in this pro­ject.
