The PiLas Systems are diode lasers emitting very short optical pulses with pulse widths down to 18 ps (FWHM), depending on the laser diode used. The standard system consists of a digital electrical pulse generator EIG, an optical head with a laser diode and a collimating optics (paralleling optics, single mode fiber output or multimode fiber output versions are also available). The laser diodes of the various models are pre-configured to emit on a fixed wavelength within a spectral range between 375 nm and 1550 nm, i.e.
