摘要： The present invention relates to a laser light-source apparatus and a method of producing a laser beam, and particularly to a laser light-source apparatus capable of generating intermittent pulse light having a predetermined flickering time and emphasizing the brightness of its peak by a Bartley effect. A timing circuit forms a timing signal so as to allow an excitation type laser light source to produce the intermittent pulse light having the predetermined flickering time. A pumping laser pumps the excitation type laser light source based on the signal outputted from the timing circuit. The intermittent pulse light is flickering slower than a flicker value of a normal person in cycle. The time required to put out the intermittent pulse light is set to a time or so required to restore the sensitivity of each of human eyes to the maximum sensitivity after the human eyes have felt brightness since light has been launched into the human eyes.

摘要： The present invention relates to a laser oscillating apparatus using a semiconductor laser or the like and a method of driving a laser beam source. The present invention relates particularly to a laser oscillating apparatus or the like having a nonlinear optical medium for generating a second harmonic and capable of by-pulse driving a laser beam source with high efficiency. In the laser oscillating apparatus, a optical resonator is composed of at least a laser crystal and an output mirror. The nonlinear optical medium for generating the second harmonic is inserted into the optical resonator. The laser beam source can effect pumping on the optical resonator so that the period T of a drive pulse produced from a pulse driving means satisfies a relation in .tau..sub.FL >T-.tau. with respect to .tau..sub.FL (fluorescence lifetime). Further, a first pulse can drive the laser beam source with the degree of not leading to the emission of a laser beam and a second pulse can drive the laser beam source so that the laser beam source produces the laser beam.
