Abstract: To provide a laser oscillator allowing the use of a plastic lens in a semiconductor laser module for a high-output laser oscillator while being unlikely to reduce the efficiency of coupling to an optical fiber even if a laser output changes. A laser oscillator comprises a semiconductor laser module with multiple semiconductor laser elements. The laser oscillator comprises: multiple lenses in a first group provided in the semiconductor laser module for causing laser beams from the semiconductor laser elements to pass through; and a lens in a second group provided in the semiconductor laser module for causing all beams having passed through the multiple lenses in the first group to pass through. The lenses in the first group are plastic lenses. The lens in the second group is a glass lens.

Abstract: Provided is a soldering system that can raise the work efficiency related to the supply of a soldering target and soldering work, while decreasing the oxygen concentration by maintaining high airtightness in a space surrounding the soldering target. A soldering system includes a soldering device and a robot related to the soldering device, in which the soldering device is equipped with a container having an openable lid and accommodating a soldering target, and the robot performs conveying of the soldering target to the soldering device and opening/closing of the lid. In an embodiment of the soldering device, the container is a double structure in which an inner container is accommodated in an outer container, and a first nitrogen supply pipe and second nitrogen supply pipe, which are inert gas supply parts of separate systems, are respectively connected to the inner container and outer container.

Abstract: A laser oscillator comprises a heat exchanger which cools a gas medium. The heat exchanger includes a cooling part which performs heat exchange between the gas medium and a cooling medium, a tubular member fixed to a frame body, and a foreign matter collection container. The tubular member is disposed so that the gas medium which flows out of the cooling part moves along an outer surface of the tubular member and then changes a proceeding direction to flow into an inlet portion. The foreign matter collection container collects foreign matters which are separated from a flow of the gas medium.

Abstract: A gas laser apparatus includes an actual laser output acquiring unit that acquires a first actual laser output at a predetermined laser output command after passage of a predetermined time from issuing of a first laser gas pressure command and acquires a second actual laser output at the predetermined laser output command after passage of the predetermined time from issuing of a second laser gas pressure command smaller than the first laser gas pressure command and a determining unit that determines whether the composition ratio of a laser gas in a gas container is normal or not by comparing the first actual laser output with a first reference output and comparing the second actual laser output with a second reference output smaller than the first reference output.
