Method and device for controlling the power transmitted by a laser to a reference point, soldering device and method

摘要

In accordance with said control method, the transmission of the laser beam is periodically interrupted with the aid of means for masking the laser beam placed between the reference point and a source of the laser beam. Moreover, the transmission power of the source of the laser beam is varied between the minimum and maximum values, such that the emission times of the source of the laser beam at the minimum power substantially coincide with the masking times of the laser beam via the masking means. Preferably, the minimum value is at least equal to 10% and the maximum value at most equal to 90% of a maximum emission power of the source of the laser beam.

1. A method for controlling power transmitted by a laser beam to a point, the method comprising:
periodically interrupting transmission of the laser beam with a masking device that masks the laser beam, the masking device being placed between the point and a laser beam source; and varying an emissive power of the laser beam source between minimum and maximum values, wherein
emission intervals of the laser beam source at the minimum power substantially coincide with intervals during which the laser beam is masked by the masking device, andthe minimum value being equal to at least 10% of a maximum emissive power of the laser beam source.
