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. |

1. A laser apparatus comprising:
a first gain medium; a partially-reflecting mirror placed on a side of one end surface of the first gain medium; a second gain medium; a partially-reflecting mirror placed on a side of one end surface of the second gain medium; a first wavelength selection filter; a second wavelength selection filter; a third wavelength selection filter; a first mirror; and a second mirror, wherein a wavelength of first laser light emitted from the one end surface of the first gain medium is different from a wavelength of second laser light emitted from the one end surface of the second gain medium, wherein each of the first wavelength selection filter, the second wavelength selection filter, and the third wavelength selection filter includes a first input/output port, a second input/output port, a third input/output port, and a fourth input/output port, wherein for light to be selected having a selected wavelength, the first input/output port is connected with the second input/output port, and the third input/output port is connected with the fourth input/output port; for light not to be selected, the first input/output port is connected with the third input/output port, and the second input/output port is connected with the fourth input/output port, wherein the third wavelength selection filter is a wavelength selection filter to select light having wavelengths that cyclically exist in the light, as the light to be selected, wherein another end surface of the first gain medium is connected with the first input/output port of the first wavelength selection filter, wherein another end surface of the second gain medium is connected with the first input/output port of the second wavelength selection filter, wherein the fourth input/output port of the first wavelength selection filter is connected with the first mirror, wherein the fourth input/output port of the second wavelength selection filter is connected with the second mirror, wherein the first input/output port of the third wavelength selection filter is connected with the second input/output port of the first wavelength selection filter, wherein the second input/output port of the third wavelength selection filter is connected with the second input/output port of the second wavelength selection filter. |
