	For controlling the dynamics of a storage ring FEL, we propose to inject the FEL oscillator with an external laser [1]. Another purpose is generation of long sustain and intense coherent synchrotron radiation with combining Q-switched and injected FEL [2]. In this presentation, we will report on technical developments for injecting the external laser to FEL oscillator, which works both in CW and Q-switched operation. Optical system for injecting external laser and RF modulation system for Q-switching are newly developed. Practical problems and way to overcome them will be discussed. [1] C.
