Abstract： We demonstrate dispersion engineered dissipative soliton mode locked lasers, by means of intracavity spatial light modulation (SLM). The inline cavity GVD control of wide range (-0.28 ps² ~ 0.06 ps²) in the laser cavity is realized, by which we achieve continuous and stable switching of traditional solitons, dispersion-managed solitons and dissipative solitons. A transient process of pulse-adaptive reconstruction is observed during the switching of different solitons. Transitions of soliton dispersive waves from Kelly sidebands, and transforms to quartic solitons have been observed via tuning the high-order dispersion coefficients. w-shaped solitons are demonstrated under negitive second-order dispersion and positive fourth order dispersion.
