摘要： A laser system comprises a laser (500) whose output beam is delivered to a workpiece (504) by an optical fiber (502). A transducer (506) detects the power of light propagating in the cladding layer of fiber (502) at a position near its input end. The transducer (506) also strips out the light travelling in the cladding layer. The output of transducer (506) is divided by the output of a transducer (507), which detects the power of the output beam of laser (500), to produce a signal indicative of misalignment between the laser beam and the core of fiber (502) at the input face. A transducer (505) comprises a second fiber (508) optically coupled with the cladding layer of fiber (502). Light emitted from the ends of fiber (508) is detected by a pair of detectors (509, 510), whose outputs are indicated on displays (512, 514). Display (512) provides information on the integrity of transmissions of the laser beam through fiber (502). Display ( 514) provides information on the material processing operation performed on workpiece (504), and also on the focus of the beam onto the workpiece.

摘要： Various examples of an optically pumped laser are described. In each example, a laser member formed from active laser material is located in an optical cavity and a source of pumping light is arranged so that pumping light passes into the laser member through a side surface. A deflecting means is provided which ensures that the pumping light makes an initial pass followed by at least one, and preferably at least two, further passes across the laser member. In the further passes, the pumping light has a substantial component long the optical axis. Consequently, a relatively long absorption path for the pumping light is achieved. In one example, the laser member is an Nd:YAG bar (20), the pumping light source is an array (23) of laser diodes, and the deflecting means takes the form of a series of facets (27) formed along a side of the bar (20). In another example, the deflecting means is a diffraction grating.

摘要： A dispersive prism arrangement comprises a pair of identical triangular prisms each of which is mounted on a platform. The two platforms are rotatably mounted on a common shaft which slides in a groove and each platform is also mounted on a respective shaft which slides in a respective groove. These two further shafts are biased outwardly by springs. The two prisms are symmetrically disposed about the common shaft. Equal but opposite rotation may be imparted to the two prisms by rotating a knob which drives the common shaft.A multiwavelength input beam incident on the first face of the first prism is refracted at this face, reflected at the second and third faces, emerges after refraction at the second face, and makes a symmetrical passage through the second prism. The prisms may be rotated so that each component of the beam emerges from the second prism without offset or deviation relate to the input beam.
