Claim:
1. A laser device, comprising: a laser light generating unit that includes a first light source that generates pulse laser light with a first wavelength and a second light source that generates pulse laser light with a second wavelength; an amplifying unit equipped with an amplifier achieving gain in light in a wavelength range that includes the first wavelength and the second wavelength, which outputs first amplified light obtained by amplifying the laser light with the first wavelength and second amplified light obtained by amplifying the laser light with the second wavelength; a wavelength converting unit that converts light from one wavelength to another wavelength, the wavelength converting unit including a wavelength conversion optical element, which either converts the first amplified light to first converted light through wavelength conversion and generates a light output through wavelength conversion of the first converted light and the second amplified light or converts the first amplified light to first converted light and the second amplified light to second converted light and generates a light output through wavelength conversion of the first converted light and the second converted light; and a control unit that controls operation of the laser light generating unit, wherein: the control unit controls an output condition of the light output by adjusting a temporal overlap of the first converted light and the second amplified light or a temporal overlap of the first converted light and the second converted light at a position at which the light output is generated in the wavelength converting unit, through control of timing with which the laser light with the first wavelength is output from the first light source and the timing with which the laser light with the second wavelength is output from the second light source relative to each other; and a wavelength of the light output from the wavelength converting unit is different from the first wavelength and is also different from the second wavelength.
