 Download PDF user manual


FLD-2U is a family of flashlamp drivers (syn. laser power supplies) for pulsed flashlamp pumped solid-state lasers such as Nd:YAG, Er:YAG, Alexandrite etc.

Module's input is 230VAC mains, module's output is flashlamp.
Discharge type is partial, pulse shape is "quasi-rectangular". Complete discharge with bell-shaped pulses is available as an option.

A lot of options is available:

  • different output voltages (up to 900V)
  • different output powers (up to 1750W)
  • different parameters adjustment ranges
  • external/internal triggering
  • Pockels cell driver as an option
