Laser Output (continued)
High Speed Operation, FLASH1
and VOLT B are set to approximately the same amplitude, the laser output becomes larger, but
the second (FLASH2) shot cannot be emitted immediately after FLASH1. So, you must set the
schedule with VOLT A essentially equal to VOLT B as follows (refer to Figure 6-5):
