摘要： Laser light having a wavelength where a thin-film semiconductor layer can absorb the laser light is applied on the side of the thin-film semiconductor layer to join a semiconductor-holding member and a metal member by welding. Materials can be joined at a sufficiently high strength and with long term stability especially when a metal member of the same or different type is welded to a conductive substrate which is a part of a photovoltaic device.

摘要： A selective laser sintering apparatus and method is disclosed, in which the laser power is controlled according to the scan velocity. The scanning system, which includes a pair of galvanometer-controlled mirrors for directing the aim of the laser beam, generates signals indicative of either the position or scan velocity of the aim of the beam, in either one or two directions. The signals are gated in the laser power control system so as to pass the signals only during those times at which the laser is to be turned on. A laser power control system receives the signals and, in the case of position signals, differentiates the signals to generate velocity signals. The velocity signals are used to derive a scan velocity, and the scan velocity is multiplied by the desired laser power at full scan velocity to produce a laser power control signal. By making the laser power dependent upon the scan velocity, a constant laser energy flux density is applied to powder at the target surface, even during acceleration and deceleration intervals at the beginning and end of a scan, respectively.
摘要翻译：公开了一种根据扫描速度控制激光功率的选择性激光烧结装置和方法。包括一对用于引导激光束目标的电流计控制反射镜的扫描系统产生指示光束的目标的位置或扫描速度的信号，在一个或两个方向上。这些信号在激光功率控制系统中选通，以便仅在激光器被打开的时间内传递信号。激光功率控制系统接收信号，并且在位置信号的情况下，区分信号以产生速度信号。速度信号用于导出扫描速度，扫描速度以全扫描速度乘以期望的激光功率，以产生激光功率控制信号。通过使激光功率取决于扫描速度，即使在扫描开始和结束时的加速和减速间隔期间，激光能量通量密度均匀地施加到目标表面上的粉末。

摘要： In order to obtain a weld bead having a good outer appearance with little splash of sputters or the like and a sufficient shearing force, there is provided a flash lamp control section for controlling flash lamps so as to generate two rectangular waves in a pulse wave form at every cycle of a pulse laser beam generated by a pulse YAG laser during the irradiation of the pulse laser beam on coated metal materials. The flash lamp control section is adapted to control a relationship between a peak power and a pulse width of a first rectangular wave and a peak power and a pulse width of a second rectangular wave in predetermined ranges. Under the control of the flash lamp control section, the pulse laser beam generated by the pulse YAG laser is irradiated to the coated metal materials thereby carry out the irradiating operation.
