In today’s economic climate, those working with industrial high-power lasers should be doing everything they can to maintain one of their most valuable tools at its peak performance and optimize the processes for which they are used. In today’s economic climate, those working with industrial high-power lasers should be doing everything they can to maintain one of their most valuable tools at its peak performance and optimize the processes for which they are used. As technology progresses, more techniques are available to laser users to optimize the application of their lasers, with the goal of maximizing throughput and minimizing downtime. Laser output power, along with focused spot size and its temporal location, are crucial to optimizing the laser process. Material processing is an idea as old as time itself; however, using a laser for joining, cutting, ablating, etc. is something that is relatively new to mankind. Several different lasing techniques have served well over the past few decades, but it is no secret that the fiber laser, with its high wall-plug efficiency and high beam quality, has changed the way we produce parts with a laser. But two things have not...
