Abstract
A laser apparatus includes first and second gain media; first, second, and third wavelength selection filters; and first and second mirrors. The wavelengths of first and second laser light emitted from end surfaces of the first and second gain media, respectively, are different from each other. The third wavelength selection filter is a wavelength selection filter to select light having wavelengths that cyclically exist in the light, as light to be selected. The other end surfaces of the first and second gain media are connected with the first input/output ports of the first and second wavelength selection filters, respectively. The fourth input/output ports of the first and second gain media are connected with the first and second mirrors, respectively. The first and second input/output ports of the third wavelength selection filter are connected with the second input/output ports of the first and second wavelength selection filters, respectively.
