Methods and systems for determining the throughput of a fiber bundle are provided. A first optical sensor and a second optical sensor ascertain a series of baselines before general weld operation, wherein the first optical sensor ascertains only laser energy output directly from a laser source and the second optical sensor ascertains laser energy output directly from the laser source and laser energy reflected back through the fiber bundle. During general weld operation, the first optical sensor and the second optical sensor continue to measure their corresponding laser source outputs and provide these measurements to a control module. The control module compares the outputs against the baselines to determine whether the fiber bundle throughput falls below a threshold.
A complementary optical part is disposed so that it surrounds and abuts a transmissive plastic part in TTIr laser welding. The complementary optical part includes a complementary portion having an inner surface that has a negative complementary shape to a shape of a laser facing surface of the transmissive plastic part and an outer portion that has an outer surface. The complementary optical part is transmissive and has the same index of refraction as the transmissive plastic part. The complementary optical part is disposed so that the inner surface of the complementary portion abuts the laser facing surface of the transmissive plastic part. Since the complementary optical part and the transmissive plastic part have the same index of refraction, the infrared laser beam travels in a straight line through the complementary optical part and the transmissive plastic part.

SIMULTANEOUS LASER WELDING USING TWO-MICRON LASER LIGHT
Plastic parts are welded in a laser welding system. At least one of the plastic parts is a partially absorptive plastic part that is partially absorptive to laser light at an absorption wavelength in a range of 1.6 microns to 2.4 microns. In an aspect, the plastic parts are welded in a two-micron simultaneous laser welding system in which the plastic parts are received. In an aspect, the plastic parts are welded in an intersecting multi-beam laser welding that includes a two-micron simultaneous laser welding subsystem and a second laser welding subsystem. In an aspect, the second laser welding subsystem is a two-micron simultaneous laser welding subsystem. In an aspect, the second laser welding subsystem includes one or more trace laser welding subsystems.
Plastic parts are welded with a true 3D volumetric weld using intersecting multi-beam trace laser welding in which a plurality of spot laser beams having the same wavelength are directed to the so that the laser beams intersect each other at a point along a weld path within one of the plastic parts at an angle in an intersection angle range between ten degrees and ninety degrees. The plurality of laser beams are traced so that the intersection of the plurality of laser beams traces along the weld path to form a weld pattern that is linear, curvilinear, planar or three dimensional along a joint that is inside a volume of plastic. The plastic part in which the laser beams intersect is partially absorptive to laser light at a wavelength and the laser beams have this wavelength.
Plastic parts are welded in a laser welding system. An infrared laser source in a laser chamber is controlled by a controller using closed-loop feedback control with a corrected feedback signal that is compensated for background infrared radiation in the laser chamber. Prior to the infrared laser source being turned on, the controller senses with the optical sensor an intensity of background infrared radiation in the laser chamber. Once the laser is on, the controller senses with the optical sensor an intensity of infrared laser radiation in the laser chamber. The controller calculates the corrected feedback signal by subtracting the intensity of the background infrared radiation sensed when the infrared laser source was off from the intensity of the infrared laser radiation sensed when the infrared laser source is on.
