The temporal spread of an ## optical ultrashort pulse

lies in the range of picoseconds and below. In order to reach such short time regions,
a broad spectrum of ## phase matched

frequency terms is required. This is commonly achieved in ## mode-locked lasers

. The relevant parameters
responsible for the pulse shape are ## Δ frequency

, ## center frequency

, and ## bandwidth

(frequency spacing); they can be adjusted with the control panel above.
In case of ideal mode-locking and zero disperison the smallest possible pulse (## Fourier Limited Pulse Width

) width can be modeled as a fourier series of the individual frequency
components.
