Solid-state laser apparatus

摘要

A laser system is provided with a plurality of light emitting diodes arranged to energize the laser source. The individual diodes have separate controls so that they may be turned on separately from one another for different periods of time and to produce different amounts of illumination. A controller such as a CPU may be programmed to actuate the controllers in a desired manner to achieve to a controlled light profile upgrading versatility and accuracy of laser systems. In addition to sequencing individual light emitting diodes in various combinations, the diodes may be energized simultaneously in various combinations. A first combination may be illuminated for a relatively long time and a second combination energized to overlap part or all of the period of that first combination, or even to extend beyond the period of the first. Thus, in addition to adjusting pulse width time, time spacing between pulses and overlap of pulses may be adjusted as well as light amplitude of individual diode light sources.
