摘要:
A laser drive includes a variable output voltage source that can control an output voltage, a laser source connected to the variable output voltage source, a laser drive circuit that drives the laser source, and a monitoring controller that monitors an operating voltage of the laser drive circuit and controls the output of the variable output voltage source such that the monitored operating voltage becomes equal to a desired value.
