Abstract: A method for generating a fourth harmonic solid laser, generating a second harmonic by interacting a high power fundamental wavelength with a second harmonic nonlinear optical crystal (9), generating a fourth harmonic by entering the second harmonic into a fourth harmonic nonlinear optical crystal (12). A method is used that the second harmonic is reflected time after time in a cavity or out a cavity so as to generate an accumulative fourth harmonic. Therefore, the method can attain high efficiency and the stabilizing output frequency. The nonlinear optical crystal has long life.
