PROBLEM TO BE SOLVED: To provide a laser light adjustment method for a laser light source device, and a laser light source device, capable of emitting laser light having a desired target wavelength at a high light intensity.SOLUTION: A laser light source device comprises: a semiconductor laser emitting excitation light by being supplied current; a KTP crystal provided on an optical axis of the excitation light, and converting the excitation light into light having a target wavelength; and an etalon provided on the optical axis of the excitation light and transmitting light having a predetermined wavelength. A laser light adjustment method includes: a detection step of detecting the light intensity and the wavelength of outgoing light emitted from the laser light source device; an etalon angle adjustment step of changing an angle of the etalon so that the wavelength of the outgoing light becomes the target wavelength, and the light intensity of the outgoing light becomes a predetermined value or more; and a non-linear optical crystal angle adjustment step of changing an angle of a non-linear optical crystal so that the wavelength of the outgoing light becomes the target wavelength, and the light intensity of the outgoing light becomes the predetermined value or more. |
