¹ Minimum pulse widths depend on repetition rate.
² Peak power for collimated beam. Fiber coupling will reduce peak power. Corresponding pulse energy depends on pulse width. Range is from 1pJ to 50pJ for near Gaussian pulses. Higher pulse energy at the expense of pulse shape is possible with increased pulse duration up to 1 or 2ns. Maximum repetition rate will be limited in that case.
³ Typical average output power for collimated beam at 100 MHz is given. Average power depends on repetition rate. For repetition rate above 80MHz a passive heat sink for the laser head is required for long time operation.
⁴ The wavelength is selectable within C- and O-Band.
