Abstract :
Summary form only given. In this work we experimentally demonstrate the generation of nearly transform-limited picosecond pulse trains at 1.5 /spl mu/m using a diode-pumped bulk Er-Yb:glass laser FM-operated by an intracavity LiNbO/sub 3/ resonant phase modulator at 9.4 GHz, near the extreme repetition rate achievable with a bulk solid-state laser. The FM optical field from the laser is sent to a custom-made fiber Bragg grating acting as a sharp cut-off filter in reflection, and the filtered signal is derived through a three-port optical circulator.
