A hybrid-type passively and actively mode-locked laser-scheme,

摘要

The present invention utilizes the advantages of the conventional ultrasound optical pulse generation scheme of the passive mode locking optical fiber laser, the repetition rate conversion characteristic of general active lasers, and the ease of synchronization of optical pulses, The present invention relates to a configuration in which two loops are connected by optocouplers and one loop is composed of a nonlinear amplifying loop in a conventional passive mode locking and an optical modulator And optical gain, and is able to control the laser oscillation repetition rate by using a time delay line. In the future, high-speed time-division multiplexed optical communication, optical processor, and ultra fast optical phenomenon Will be possible.
