1Power
If multiple laser drivers and laser diodes are used to increase output power, then the laser processing system achieves higher output power, but the system volume increases
Solution Approach 1:
The patent merges multiple laser driver functions into a single integrated controller that can simultaneously control multiple laser diodes. The controller includes multiple output terminals that can independently drive different laser diodes, combining the functionality of what would traditionally require separate driver circuits into one compact unit, thereby reducing overall system volume while maintaining high output power capability
Solution Approach 2:
The controller is designed with multi-functionality to serve multiple purposes: it can control multiple laser diodes simultaneously, each output terminal can independently regulate laser output, and the single controller unit replaces what would traditionally require multiple dedicated driver circuits. This universal design allows the system to achieve high power output through multiple diodes while keeping the control system compact
