Adaptable Fiber Laser Control Unit

Today fiber laser is widely used due to their performances and flexibility. They replace old types of lasers in the industrial machines. To develop a family of laser machines it is the need of having standard laser source that could efficiently be used and replaced in the equipment, independently of the laser source or types of lasers. This paper presents the concept and development of a new fiber laser control unit developed to be used for CW, QCW or pulsed regime. Control unit could be used in multiple laser source and satisfy complex requirements. The control unit of the fiber laser source is able to be used in a different type of fiber laser like: Yb doped fiber, Erbium fiber, thulium fiber. Control unit is designed to be used direct or with minimum modifications in different laser processing applications like: marking, engraving, cutting, drilling, welding, etc. Main parameters of control unit are: 3 working regime, frequency - 1 KHz (QCW), frequency in pulsed regime : 15KHZ - 500 KHz, control seed laser, control pre amplifier and amplifier. Control unit allows commands for machine control: start/stop, interlock, system ready/ fault.
