IPG Photonics’ YLPF-FlexO femtosecond lasers offer the user unprecedented flexibility in choosing parameters optimal for the application. The YLPF-FlexO laser provides ultrashort sub-50 fs, >40 nJ pulses at 11 MHz repetition rate. The laser system incorporates IPG’s proprietary pulse shaping technology that provides the ability to choose a desired temporal pulse shape, from the shortest near-transform-limited pulse to a variety of programmable shapes. Shaped time-domain profiles and multi-pulse waveforms within +/- 3 ps time window can be created by the user via spectral phase and amplitude shaping.
|Pulse Duration from 40 fs||Repetition Rate 11 MHz|
|Output Power up to 1.1 W||Environmentally Sealed|
|Programmable Pulse Shape : Transform-limited or Shaped Pulses on Demand|
|Rugged Industrial Design, High Reliability, Long Lifetime|
Negative chirp up to 15,000 fs² can be added to the output pulse, equivalent to pulse broadening up to 1 ps. The linear chirp and higher-order dispersion corrections can be used for pre-compensation of pulse distortions by optical components in customer’s pulse delivery line. 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.
Optional extensions such as harmonic generators, higher output pulse energies and powers as well as variable repetition rate, from a single pulse to 11 MHz and its multiples, are planned.
