摘要： As a composite laser rod capable of satisfying the positional stability and output stability of a laser beam, a laser rod in which a laser active element is doped is intimately inserted into a hollow portion of a non-doped ceramic pipe that has a crystal structure the same as the laser rod followed by baking so as to remove a gap and strain at an interface between the laser rod and the ceramic pipe after the baking further followed by polishing a surface of the ceramic pipe to form a ceramic skin layer, and thereby a composite laser rod is formed. In the composite laser rod, an influence due to fluctuation in the cooling capacity of cooling water or a heat sink is averaged by a non-doped skin layer, temperature fluctuation of the laser rod is suppressed, and an influence of vibration from the cooling water or a cooling fan can be suppressed. When the refractive index of the laser rod is made higher than that of the ceramic pipe, a high efficiency oscillation can be realized, and furthermore when the thermal conductivity of the ceramic pipe is made higher than that of the laser rod, the thermal lens effect can be alleviated.

摘要： A conventional method for a solid-state laser device that obtains a laser beam output of a high quality at a high output using a laser diode as a pumping light source has a problem that the costs are increased and the fabrication becomes complicated due to an increasing number of components, such as a diffusing reflection mirror, a condenser lens, and a holding mechanism and a cooling mechanism thereof. Coating with a antireflection coating to reduce a transmission loss of laser diode light, and coating with a high reflection coating to reflect the laser diode light are provided alternately on the outer surface of a cooling tube. Also, an irradiation direction of the laser diode is not directed to the center of the laser rod, but is given with a certain angle to be positively tilted. This configuration makes it possible to eliminate the above problem.

摘要： A pair of opening portions are provided as an inlet port of refrigerant and an outlet port thereof, and refrigerant flow channels are formed left-right symmetrically in its plan view from one opening portion to the other opening portion. At the area adjusted to the area which is thermally connected to the heating element in the refrigerant flow channels, projections whose cross section thereof become smaller and smaller upward from the bottom surface of the refrigerant flow channels or downward from the upper surface, that is, widens toward the end, are formed. By joining the heat radiating plate having the projections formed therein to the other heat radiating plate, which is plate-shaped, together, a heat sink is assembled. Therefore, the heat sinks are excellent in terms of thermal conductivity and reliability, are produced at a low cost, and a laser module employing the same, a laser module apparatus, and a laser processing apparatus are obtainable.
