    • A tunable laser device for an optical measurement of combustion and exhaust gas for a vehicle is provided to be miniaturized in comparison with a conventional tunable laser device by using a transmitting diffraction grating. A tunable laser device for an optical measurement of combustion and exhaust gas for a vehicle includes a semiconductor laser light source(11), a collimating lens(12), and a transmitting diffraction grating(13), and a regulation mirror(14). The collimating lens is disposed on one side of the semiconductor laser light source to collimate a semiconductor laser. The transmitting diffraction grating is disposed on one side of the collimating lens to diffract the transmitted light. The regulation mirror is disposed on one side of the transmitting diffraction grating to return the light diffracted by the transmitting diffraction grating.
