	At the UVSOR storage ring, free electron laser (FEL) have been studied for more than a decade. After the upgrade of accelerator components in 2003, FEL lasing around 199 nm [1] has been achieved. In these years, several application experiments of the FEL in deep UV region have been carried out. A feedback alignment system of the optical resonator has been developed to improve long term stability of the laser power for user experiments. To promote application experiments more extensively, now we have two upgrade plans. One is FEL lasing with top-up operation in order to maintain a high beam current and then a high out-coupled power. The other is upgrade of the optical klystron to have higher gain at deep UV region. These two upgrades will allow us to attract more users to our FEL. [1] M.
