Applications
EKSPLA’s Pockels cell drivers are optimal for pulse picking, mode-locking, cavity dumping and q-switching of the solid state femtosecond, picosecond and nanosecond lasers. Most popular fields of applications are:
- Industrial lasers
micromachining, welding and cutting - Medical lasers
ophthalmology, dermatology and surgery - Scientific lasers
fusion research, spectroscopy, and high-energy physics
Description
Pockels cell drivers, also known a fast HV switches, are designed to load and unload capacitance of Pockels cells which serve as an integral part of electro optic modulators (EOM’s) used for pulse picking, mode-locking, cavity dumping and q-switching of solid state lasers. Ekspla’s Pockels cell drivers are optimal for BBO, RTP, KD*P, KTP, LiNbO3, CdTe Pockels cells.
Our Pockels cell drivers can provide high voltage output pulses up to 9.8 kV, repetition rates up to 6 MHz, electrical pulse rise times as short as 5.5 ns, minimal pulse durations as low as 0 ns and maximal pulse durations with no limit. All specifications are measured at 6 pF load.
Ekspla’s Pockels cell drivers require HV supply input typically equal to driver’s HV output (the only exception is PCD-FAM series drivers that allow to modulate the amplitude of each individual driver’s output pulse by analog voltage input). We provide complimentary HV power supplies for each Pockels cell driver version. For high-volume OEM customers we also tailor our Pockels cell drivers by removing excessive components to make sure products are optimal parameter, cost and size wise.
