摘　　要：The nonlinear physics dynamics of temporal dissipative solitons in a microcavity hinder them from attaining high power from pump lasers with a typical nonlinear energy conversion efficiency of less than 1%.Here,we experimentally demonstrate a straightforward method for improving the output power of soliton combs using a silica microrod cavity with high coupling strength,large mode volume,and high-Q factor,resulting in a low-repetition-rate dissipative soliton(∼21 GHz)with an energy conversion efficiency exceeding 20%.Furthermore,by generating an∼105 GHz 5×FSR(free spectral range)soliton crystal comb in the microcavity,the energy conversion efficiency can be further increased up to 56%.
