Abstract:
A solid-state laser device, comprisinga first optical axis, a second optical axis crossing said first optical axis, a first resonator arranged on said first optical axis and for oscillating a first fundamental wave between a first concave mirror and a plane output mirror, a second resonator arranged on said second optical axis and for oscillating a second fundamental wave between a second concave mirror and said plane output mirror, a first light emitter for entering an excitation light to said first resonator, a second light emitter for entering an excitation light to said second resonator, a wavelength separating plate arranged on a portion where said first optical axis crosses said second optical axis and for deflecting said second optical axis so as to form a common optical axis portion which is commonly used by said first optical axis and said second optical axis, an optical member for wavelength conversion arranged between said plane output mirror and said wavelength separating plate, and a wavelength switching means capable of inserting or removing said optical member for wavelength conversion with respect to said common optical axis portion, wherein said output plane mirror is arranged on said common optical axis portion and is commonly used by said first resonator and said second resonator, said wavelength separating plate transmits the first fundamental wave, and reflects the second fundamental wave on said common optical axis portion, said optical member for wavelength conversion comprises a plurality of optical crystals for wavelength conversion, and said wavelength switching means selectively inserts said optical crystals for wavelength conversion in said common optical axis portion.
