Description

NanoFlux series electro-optically Q-switched nanosecond Nd:YAG amplifier systems deliver high energy pulses at high repetition rates.

A diode-pumped Q-switched nanosecond laser, based on industry-tested technology is used as a master oscillator of the system. It produces high-intensity, high-brightness pulses and is well suited for further amplification in linear amplifiers for high-energy Super-Gaussian output pulses. Employing electro-optical cavity dumping, the master oscillator can produce pulses which are as short as several ns with uniform beam profile and low divergence.

Alternatively customers own seed source can be implemented as master oscillator and amplified to required energy level for further amplification in main power amplifiers.

Power amplifiers are a chain of low-maintenance diode-pumped single and double pass amplifiers where pulses are amplified up to the required energy. During amplification, spatial beam shaping is employed in order to get a Super-Gaussian beam shape at the output.

Angle-tuned non-linear crystals harmonic generators mounted in temperature stabilized heaters are used for second and third harmonic generation. Harmonic separation system is designed to ensure high spectral purity of radiation and direct it to the output ports.

System control is available through control pad, USB and LAN interfaces (RS232 as optional). The system can be controlled from personal computer with supplied software for Windows operating system.

To tailor the laser for specific applications or requirements, various customization possibilities are available such as industrial grade, portable laser housing with integrated power supplies and cooling units; customer’s seed integration; multi-channel outputs; burst amplification and various other.

  1. Due to continuous improvement, all specifications are subject to change without notice. The parameters marked ‘typical’ are indications of typical performance and will vary with each unit we manufacture. Presented parameters can be customized to meet customer‘s requirements. All parameters measured at 1064 nm if not stated otherwise.
  2. Harmonic outputs are optional. Specifications valid with respective harmonic module purchased. Outputs are not simultaneous.
  3. Second harmonic specification is valid when only SH option is ordered. If TH/FH options are orders second harmonic efficiency is reduced to ~50%.
  4. Standard pulse duration is 5 ns. Other pulse durations can be ordered within range of 0.2 – 500 ns. Output energy might differ depending on duration.
  5. Under stable environmental conditions, normalized to average pulse energy (RMS, averaged from 60 s). Energy stability in burst mode heavily depends on temporal burst shape.
  6. Measured over 8 hours period after 30 min warm-up when ambient temperature variation is less than ±2 °C.
  7. Super-Gaussian spatial mode of 6-11th order in near field.
  8. Beam diameter is measured at signal output at 1/e2 level for Gaussian beams and FWHM level for Super-Gaussian beams.
  9. Beam pointing stability is evaluated as movement of the beam centroid in the focal plane of a focusing element (RMS, averaged from 60 s).
  10. Optical pulse jitter with respect to electrical outputs: Trig out > 3.5 V @ 50 Ω.
  11. System sizes are preliminary and depend on customer lab layout and additional options purchased.
  12. Longer umbilical with up to 5 m available upon request.
  13. The laser and auxiliary units must be settled in such a place void of dust and aerosols. It is advisable to operate the laser in air conditioned room, provided that the laser is placed at a distance from air conditioning outlets. The laser should be positioned on a solid worktable. Access from one side should be ensured.
  14. Voltage fluctuations allowed are +10 % / -15 % from nominal value.
  15. Power consumption and water supply requirements deviate depending on system configuration.

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.
