FLD-4U flashlamp driver

FLD-4U is a family of high-power flashlamp drivers for pulsed flashlamp pumped solid-state lasers such as Nd:YAG, Er:YAG, Alexandrite, etc. and other pulsed lighting, particularly IPL.

FLD-4U drivers are all-in-one solution, they include all the necessary subsystems: control board, capacitor bank, capacitor charging power supply, simmer supply and discharge circuit (discharge circuits). The drivers are able to:

• charge a capacitor bank up to defined value,
• provide initiating flash voltage pulses with required width and repetition rate (in internal synchronization mode) or with required width (in external synchronization mode),
• provide a simmer arc during the interval between pulses,
• set up user-defined delay between output signals to flashlamp and synchro pulse.

Optionally, we produce FLD-4U with already incorporated Pockels cell driver, in this case the next parameters are also under FLD-4U control:

• voltage on the Pockels cell, value and turning on/off,
• user-defined delay between Pockels cell driver switching and pulse to flashlamp,
• a period between individual pulses in a pulse train during Q-switch operation mode (as option).

FLD-4U is offered with one or two output channels, and up to two connected in series flashlamps could be attached to every output. So, each FLD-4U module is able to drive up to four flashlamps.

Drivers are 19''-rack mounted, with 4U height and ~400 mm depth.

All the important parameters (output voltage, pulse width, pulse repetition rate and others) could be set up via front panel user interface (7'' colour touch screen display) and RS-232 machine interface.
