    Abstract: A laser apparatus includes light source elements outputting laser beams; a wavelength-selecting element disposed in an optical path of each of the laser beams and configured to cause light in a predetermined wavelength band to selectively transmit therethrough; and a partially transmissive-reflector that receives the light transmitted through the wavelength-selecting element, reflects a part of the input light toward the wavelength-selecting element, and causes its remainder to transmit therethrough. The wavelength-selecting element causes a part of the respective laser beams output from the respective light source elements to selectively transmit therethrough, the partially transmissive-reflector reflects a part of the respective transmitted laser beams, and the wavelength-selecting element causes a part of the respective reflected laser beams to transmit to return to the light source elements, and each of the light source elements preferentially oscillates at a wavelength of the laser beam that transmits through the wavelength-selecting element.
