A method of controlling chaos is presented via dual-wedges in a delayed feedback semiconductor laser. The physical model of the laser dynamics is set up under the condition of the dual-wedges control. The optical-length of the transmission of feedback light in the external cavity can be governed by modulating the dual-wedges while the delay time and feedback intensity of the feedback light are varied. The dual-parameter chaos-control of the delay time and feedback intensity can be physically realized. The chaotic laser can be controlled in periodic states and its mean pulse power increased, as shown by numerical simulations.
