YLPF-FlexO 50 fs, 1W

Femtosecond Fiber Laser

YLPF-FlexO Series of femtosecond ytterbium fiber lasers offer the user unprecedented flexibility in choosing parameters optimal for the application. The YLPF-FlexO lasers provide sub-50 fs at 11 MHz repetition rate. Arbitrary pulse sequences and bursts within the 11 MHz train can be selected by the user. The YLPF-FlexO lasers incorporate IPG’s proprietary pulse shaping technology which provides the ability to choose a desired temporal pulse shape from the shortest near-transform limited pulse to a variety of pre-selected shapes. The pulse shaping technology can be incorporated in a closed loop setup responding in real time, on the sub-second time scale, to input from external diagnostics.
