Nd:YLF mode-locked 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. Harmonic 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 is standard feature 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 operated from master device or personal computer through USB (VCP, ASCII commands), RS232 (ASCII commands) or LAN (REST API) interfaces or from remote control pad with backlit display that is easy to read even while wearing laser safety glasses.

  1. Due to continuous improvement, all specifications are subject to change without notice. Parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise all specifications are measured at 1053 nm and for basic system without options.
  2. For -SH option. Outputs are not simultaneous. Please inquiry for pulse energies at other wavelengths.
  3. With auxiliary H400 harmonic generator unit. Outputs are not simultaneous. Please inquiry for pulse energies at other wavelengths.
  4. Inquiry for optional pulse durations in 20 – 80 ps range.
  5. With respect to optical pulse. <10 ps jitter is provided with PRETRIG standard feature.
  6. SYNC OUT lead or delay can be adjusted with ~0.25 ns steps in specified range. PRETRIG standard feature provide -1000..5000 μs lead/delay time adjustment range.
  7. Mains voltage should be specified when ordering.

Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.


Provides low jitter pulse for streak camera triggering with delay in -1000…5100 µs  range and <10 ps rms jitter.
