We report an industrial grade picosecond and femtosecond pulse Yb fiber lasers with >100 μJ pulse energy and hundreds of Watts of average power for improved laser machining speed of sapphire and glass. This highly efficient laser offers >25% wall plug efficiency within a compact 3U rack-mountable configuration plus a long >2m fiber delivery cable. Reconfigurable features such as controllable repetition rate, fine pulse duration control, burst mode operation and adjustable pulse energy permit the customer to tailor the laser to their application.
100W linear-polarized single-mode CW emission is demonstrated in an all-fiber format at 1566 nm. The Yb<sup>3+</sup>/Er<sup>3+</sup> doped fiber laser has an extinction ratio >20 dB and M<sup>2</sup><1.1. Using an Yb-Er doped multi-mode fiber, the laser provides > 13% overall electrical efficiency and less than 4 nm linewidth without the onset of Yb ions generation at wavelength range of 1060-1080 nm. There are no saturation effects due to pump or nonlinear phenomena. Parasitic lasing is suppressed with fiber laser cavity design and specialty filters.
