PROBLEM TO BE SOLVED: To provide a solid-state laser device which can project laser beams with a plurality of wavelengths by using a simple mechanism. SOLUTION: A solid-state laser device comprises a first optical axis 20 and a second optical axis 29 which have a common optical axis portion 20a and are separated by an optical axis separating means 34, a first resonator 30 formed on the first optical axis, a second resonator 37 formed on the second optical axis, a first light emitter 27 for allowing an excitation lightλto enter the first resonator, a second light emitter 35 for allowing an excitation light to enter the second resonator, a wavelength conversion portion 25 provided on the common optical axis portion, and an output mirror 26 provided on the exit side of the wavelength conversion portion. The wavelength conversion portion has a plurality of wavelength conversion optical crystals 25a, 25b, and 25c. The output mirror has a plurality of individual output mirrors 26a, 26b, 26c, 26d, and 26e. The wavelength of a laser beam to be projected is determined by selection of turning-on or turning-off of the first light emitter and the second light emitter, and also by selection of the wavelength conversion optical crystals and the individual output mirrors depending on turning-on and turning-off of the first light emitter and the second light emitter.
