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, such as IPL, sun simulation, UV curing, sterilization.

FLD-4U drivers are an all-in-one solution, they include all the necessary subsystems: a control board, capacitor bank, capacitor charging power supply, simmer supply and an IGBT-based discharge circuit (one or several). These drivers are able to:

• charge the embedded capacitor bank to a user-defined value,
• provide voltage pulses with the required width and repetition rate,
• provide a simmer arc during the intervals between pulses,
• set up an user-defined delay between output signals to the flashlamp and synchro pulse.

Optionally, the FLD-4U can be supplied with an integrated Pockels cell driver. In this configuration, the following parameters are also controlled by the FLD-4U:

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

FLD-4U is offered with one or two output channels. Due to powerful simmer boards, up to two flashlamps connected in series can be attached to each output. So, a single FLD-4U unit can drive up to four flashlamps.

These high-power flashlamp drivers are designed for 19” rack mounting, with a 4U height and approximately 500 mm depth.

All key operating parameters — such as output voltage, pulse width, pulse repetition rate, and others — can be configured via the front panel user interface (7” color touch screen display) or through the RS-232 machine interface (RS-485 available upon request).
