Abstract

We report a passively Er3⁺-doped mode-locked fiber laser based on repetition rate multiplication, in which a three-stage Mach Zehnder interference structure is employed as a repetition rate multiplier. The initial soliton pulses are generated from a ring cavity with a fundamental repetition rate of 102.70 MHz, which is a seed laser. When the intrinsic frequency of repetition rate multiplier is almost aligned with a variable optical delay line, the initial repetition rate output from a seed laser, is lifted from 100.20 MHz to 801.03 MHz. This result demonstrates a method to achieve high repetition rate (> 500 MHz) pulse lasers, which avoids the limitation of cavity length on the repetition rate.
