In this paper, a 1 kW fiber laser with phase-change cool storage technique is proposed and demonstrated. The phase change materials (PCMs) containing copper foam are filled into the heat sink of the fiber laser. The waste heat can be quickly diffused into the PCMs due to the high thermal conductivity and enormous surface area of copper foam. The fiber laser has a maximum output power of 1.2kW, an electro-optical efficiency of roughly 38%, a weight of roughly 17kg, and a dimension of 330×370×86 mm3 . The fiber laser can operate at maximum power for more than 5 minutes. The power-to-weight ratio of the fiber laser is around 70W/kg (not include power supply equipment).
