Although Figure 9 Lasers have a difficulty in self-starting, inserting a nonreciprocal phase shifter improved the problem.
In this work, we inserted an acousto-optic modulator instead of a nonreciprocal phase shifter, we succeeded in reducing the mode-locking threshold and making self-starting easier.
