Ekspla PL3140 Series Picosecond Nd:YLF Lasers

PL3140 series picosecond mode locked NdYLF laser 1

Ekspla Nd:YLF mode-locked PL3143 series picosecond lasers produces high energy pulses with as short as 10 ps pulse duration.

Rugged and Reliable Design

Diode pumped mode-locked quasi‑CW master oscillator produces the train of the pulses that is guided to the regenerative amplifier for further amplification. The single pulse is cavity‑dumped from regenerative amplifier and then amplified by linear amplifiers to up to 80 mJ pulse energy. The output pulse energy can be adjusted in approximately 1 % steps from 1 mJ to nominal output, at the same time pulse-to-pulse energy stability remains less than 1.5 % rms at 1053 nm.

Angle-tuned KD*P and KDP crystals mounted in thermostabilised ovens are used for second, third and fourth harmonic generation. Harmonics separators ensure high spectral purity of each harmonic directed to different output port. Build in energy monitors continuously monitors output pulse energy. Data from the energy monitor can be seen on the remote keypad or on PC monitor.

The laser provides triggering pulse for synchronization of customer‘s equipment with lead up to 500 ns. The lead of triggering pulse can be adjusted in ~0.25 ns steps from control pad or PC. PRETRIG option is offered for streak camera triggering  and can provide pulse with up to 1000 μs lead that can be adjusted from PC with approx. 33 ns step.

Simple and Convenient Laser Control

For customer convenience the laser can be controlled via user-friendly remote control pad. The remote pad allows easy control of all the parameters and features a backlit display that is easy to read even when wearing laser safety eyewear. Alternatively, the laser can be controlled from personal computer via USB port using supplied software for Windows™ operating system. LabView™ drivers are supplied as well. Read more.
