A HYBRID-TYPE PASSIVELY AND ACTIVELY MODE-LOCKED LASER SCHEME

摘要

The present invention utilizes the advantages of the ultra-short optical pulse generation composition of the conventional passive mode-locking fiber laser composition and the repetition characteristic of the general active laser, and the conversion characteristics and the easy synchronization of the optical pulses, thereby allowing the repetition to be easily converted to the conversion characteristics. It is a composition that can obtain ultra-short optical pulses with pulse synchronization characteristics. Two loops have a laser structure connected by an optocoupler. One loop consists of a nonlinear amplification loop in the conventional passive mode locking and the other loop has It is designed to induce active mode locking, including optical modulator and optical gain, and to adjust the laser oscillation repetition rate using time delay line.In the future, high speed ultra short optical pulse is used for high speed time division multiple optical communication, optical processor, and high speed optical phenomenon analysis. Application is possible.
