The usage of batteries has rapidly increased in recent years with new portable electrical and energy storage devices, as well as electric cars. This increased use of batteries in everyday life needs an increased level of efficiency, which is what fiber lasers provide, particularly as they can weld dissimilar metals. With battery usage only likely to increase, reliable and robust lasers are needed to support this.
