iNOPA™ is a white light continuum-seeded, non-collinear, optical parametric amplifier capable of generating extremely short pulses when pumped by the Model IMPULSETMYb-doped Fiber Oscillator/Amplifier. To generate short pulses the output beam of the Model IMPULSE laser is split into two beams inside the Model iNOPA enclosure. One beam is used to generate an extremely broad continuum seed beam which is then amplified by the second, higher intensity beam from IMPULSETMin a BBO crystal operated in a non-collinear arrangement. Non-collinear amplification preserves the very broad linewidth of the seed beam, which can then be compressed to a pulsewidth as short as 15 fs in a prism compressor. Non-collinear amplification is preferred since the resulting pulsewidth is dependent only on the bandwidth of the seed and not on the pulsewidth of the pump laser. In fact, conversion efficiency is improved by having a longer, rather than shorter, pump pulse because the there is more overlap in time between the two beams.
