Source: MDPI Additive-Pulse Mode Locking: A Technique for Generating Short Optical Pulses Additive-pulse mode locking, also known as coupled-cavity mode locking, is a method used in lasers to produce short optical pulses with durations in the picosecond or femtosecond range. This technique involves creating an artificial saturable absorber by utilizing nonlinear phase shifts in a […]
