A driving method for a laser light source device, a laser light source device, an image display device, a monitor device and an illumination device are provided to apply inrush current to a laser light source in the initial driving and reduce the current before the temperature of a wavelength conversion device reaches a specified value in order to secure the favored laser beam in a short time. A laser light source device(1) includes a laser light source(2), a wavelength conversion device(3) converting the wavelength of the light emitted from the laser light source, a resonator mirror(4) constituting a resonator structure between the laser light source and the resonator mirror, and a control part(5) driving the laser light source so as to cause the amount of light to decrease according to time, compared with the amount of light by the initial driving of the laser light source. A heater(6) is used to heat the wavelength conversion device when driving the laser light source.
