摘要： The present invention relates to a laser marking method which is capable of changing the grey level of a marking even in the case of a high processing speed. The laser marking method forms a marking pattern on a marking object by irradiating the marking object with pulsed light oscillated from a pulsed light source of a MOPA structure in which a semiconductor laser outputting directly-modulated pulsed light is used as a seed light source. At this time, the pulse duration of the pulsed light is changed in order to change a gray level of the marking pattern to be formed. In this way, a peak power of the pulsed light is changed by changing the pulse duration, so that it is possible to positively change the gray level of the marking pattern without changing the processing speed.

摘要： The present invention relates to a laser processing apparatus and the like having a structure for implementing at the same time both an efficient laser processing in the place where a laser beam is difficult to reach and a laser processing without damages in the place where the laser beam is easy to reach.

摘要： The present invention relates to an optically active device comprising a plurality of stages of optical amplifying sections cascaded on an input light propagation path, and a structure for effectively preventing an upstream pumping light source from being destroyed by ASE light propagating in a direction opposite to the input light. The optically active device comprises, at least, a front-stage optical amplifying section and a rear-stage optical amplifying section which are adjacent to each other on the input light propagation path. Each of the front-stage optical amplifying section and rear-stage optical amplifying section includes an amplification fiber doped with ytterbium as an optically active material and a pumping light source for supplying the amplification optical fiber with pumping light in the band of 0.98 μm for pumping the optically active material. In particular, the optically active device comprises a deterioration preventing structure for preventing the pumping light source in the front-stage optical amplifying section from deteriorating a performance. An embodiment of the deterioration preventing structure is realized by a wavelength-multiplexing fiber coupler of a wavelength division type arranged between the front-stage optical amplifying section and rear-stage optical amplifying section. The wavelength-multiplexing coupler has a port for selectively eliminating from the input light propagation path at least an ASE component in the band of 0.98 μm from backward ASE light from the rear-stage optical amplifying section.
