MIKS1_XS @ Ti:Sa Laser (Simulations)
​
Here we show the potential performance of our MIKS1_XS module driven by a Titanium Sapphire femtosecond laser. We consider relatively short 40 fs pulses at the input of our pulse compressor. A peak power increase by a factor of 4.6 could be achieved with an efficiency of over 90%. Essentially it means that we can use broadband dispersive dielectric mirrors in this case. The spectrum before and after the compressor as well as the theoretically compressed output pulses of 8.3 fs are shown below. Of course, it would also be possible to have stronger or weaker self-phase modulation and this way get even shorter or longer pulses.

Dispersion Compensation for Micromachining Setup
Here we show the performance of our MIKS1_S module driven by Carbide laser. A peak power increase by a factor of 4 could be achieved with an efficiency of 95%. The self-phase modulated spectrum and the pulse compression are shown in the graphs below.
​
On top of that we compensated the addtional dispersion introduced by the optics from the micromachining setup. This way we could achieve sub 100 fs pulse duration at the actual workpiece.
​
Laser pulses experience chromatic dispersion, i. e. varying group velocities for different wavelengths, while propagating through material. This effect stretches the pulses in the time domain. In general, shorter pulses with a wider spectrum are more susceptible to this effect. Commonly used micromachining setups comprise multiple such elements, for example beam expanders or f-theta lenses. It is thus necessary to account for the dispersion to benefit from ultrashort laser pulses on the workpiece.
​
Input Carbide: 400 mW, 40 µJ, 10 kHz, 230 fs
Output MIKS1_S: 380 mW, 38 µJ, 10 kHz, 50 fs
