Noise performance of the stretched-pulse ring laser

Summary form only given. Noise characterization on the Er-doped soliton fiber ring laser have been reported previously. These reports verify the extremely quiet operation of the soliton laser, and show that the timing jitter of the soliton laser is due to amplified spontaneous emission. The stretched pulse Er-doped fiber ring laser generates pulses whose energy is an order of magnitude larger than the soliton laser and whose pulse width can be as short of 65 fs. Therefore, it is of interest to determine whether the noise performance of this laser is comparable to that of the fiber ring soliton laser.
