Analysis and Control of Ultrashort Pulses

Propagation of Ultrashort Pulses

Electric field oscillation of few-cycle ultrashort pulse.

VirtualLab allows the propagation of

  • picosecond,
  • femtosecond, and
  • attosecond

pulses through macroscopic and microscopic optical setups. Therefore VirtualLab is using the field tracing concept, which is tracing full electromagnetic fields through the optical setup by a combination of geomectrical and physcial optics.

Optical setup consisting of several components.

Inclusion of Pulse Dispersion

Besides the fast implementation of any sophisticated ultrashort pulse source by different pulse data generators or by the import of real pulse data, VirtualLab provides a full-vectorial analysis including

  • the evaluation of the optical path length
  • pulse deformation effects like group velocity dispersion (GVD) and higher-order dispersions

which are typically caused by

  • Angular dispersion and
  • Material dispersion

Chirped Pulse.

Spatio-temporal Pulse Evolution

The application of field tracing techniques on ultrashort pulses enables the temporal and spatial evolution of a pulse by inclusion of

  • Diffraction
  • Interference
  • Local Polarization
  • Coherence
  • Dispersion

Inclusion of Important Optical Setups

Pulse focusing by off-axis parabolic mirror.

VirtualLab allows the analysis, design and optimization of optical setups for extending, shortening, focusing and shaping of ultrashort pulses. Typical setups and components are:

  • Focusing optics
  • Pulse compressor & stretcher
  • Chirped mirrors
  • Refractive and diffractive beam shapers
  • Pulse compressor & stretcher
  • Gratings
  • Spatial and spectral filters

Optimization and Tolerancing

Optimization and tolerancing of pulse compressor setups.

VirtualLab comes with a plenty of powerful algorithms for optimization and tolerancing. Typical examples are:

  • Local and global optimization of ultrashort pulse setups
  • Position and tilt tolerancing
  • Monte-Carlo simulations
  • Simulation series by parameter run
