Abstract
To provide a power supply circuit for fiber laser oscillator use capable of reducing the size of a fiber laser oscillator. A power supply circuit for fiber laser oscillator use comprises: a rectifier circuit unit capable of receiving input of a voltage having a particular value; and a power supply unit to which the rectifier circuit unit is connected. The rectifier circuit unit is one rectifier circuit unit selectable from multiple rectifier circuit units capable of receiving inputs of voltages having different values. Each of the rectifier circuit units includes a power factor correction circuit for adjusting a power factor at 1.
