PowerSpectrum pulse stretcher

TeraXion has introduced the PowerSpectrum TPSR-Xtended, a tuneable pulse stretcher designed for high-energy lasers that require a wider stretching of the pulse before the amplification chain.

TeraXion’s PowerSpectrum TPSR-Xtended is a key component for ultrafast laser designers looking to maintain high peak power without creating strong self-phase modulation that would distort the pulse. This FBG-based tunable pulse stretcher increases the stretching by up to 50 per cent, which enables an increase of energy per pulse by the same factor and equates a total stretching window up to 2,400ps. The previously proven benefits of the tuning feature have been improved to adjust the high order of dispersion from b2 to b5.

This latest improvement is an asset to tackle distortions induced by selfphase modulation, asymmetric seed spectrum and amplification, so that the highest pulse quality can be reached at any energy level. The laser material processing industry requires higher throughput at low system cost, without compromising on process stability to ensure high manufacturing yield. The TPSR-Xtended ensures industry requirements are met through its increased stretching window and b5 tuning capabilities, which allow for a constant performance for every laser.
