A semiconductor laser device includes a semiconductor laser element configured to emit a fundamental wave; a transducer configured to receive the fundamental wave incident thereon and convert a wavelength of the fundamental wave to emit wavelength converted light; a filter configured to selectively transmit wavelength range light having a desired wavelength range of the wavelength converted light; a sealing member including a light-transmitting member and configured to enclose the semiconductor laser element, the light-transmitting member being configured to receive the wavelength range light transmitted through the filter and incident on the light-transmitting member, specularly reflect part of the wavelength range light, and substantially transmit the remaining part of the wavelength range light; and a photoreceptor configured to receive the specularly reflected light from the light-transmitting member.
