Fiber lasers prove attractive for industrial applications
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.

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.
