Abstract

The extended performance capabilities of fiber lasers are increasingly used in lower-power marking, microelectronics, high-power machining, and materials-processing sector. The pulsed fiber-laser modules offer an excellent combination of beam quality and controllable pulse repetition rate, peak power, and pulse energy. With the Q-switched laser design, increasing the pulse repetition above a certain rate leads to a decrease in pulse and increase in pulse widths as peak powers decreases. All-fiber and all-guided architecture of fiber lasers offer instant turn-on operation, and facilitate heat removal and minimize external cooling requirements. Laser power modulation is used for reducing thermal effects such as the heat-affected zone (HAZ), reducing dross and permitting kerf widths of less than 20 µm. GTWave fiber-laser units with output power in excess of 450 W, increases the penetration of fiber lasers into the industrial applications.
