A multi-wavelength laser resonator is provided to obtain various laser beams through a single Nd: YAG laser rod by using totally reflective mirrors with different coatings. A multi-wavelength laser resonator includes an Nd:yag laser rod(10), total reflective mirrors(20,44), and a partial reflective mirror(30). The total reflective mirrors are formed at both ends of the Nd: YAG laser rod. A basic laser wavelength passes through the total reflective mirrors. An auxiliary reflective mirror(42) is coated such that a desired laser wavelength is reflected thereon. A blocking device prevents the basic laser from oscillating. Two laser beams with different wavelengths are emitted from the partial reflective mirror. |
