Description

ANL series electro-optically Q-switched nanosecond Nd:YAG lasers 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 flat-top 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.

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 flat top shape at the output. Optional second and third harmonic generators are based on angle-tuned nonlinear crystals placed in heaters.

For convenience, PC software for Windows™ (LabVIEW™ drivers are supplied as well) is used for laser operation, monitoring and internal system diagnostics.
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.

  1. Due to continuous improvement, all specifications subject to change without notice. Parameters marked typical may vary with each unit we manufacture.Unless stated otherwise, all specifications are measured at 1064 nm and for basic system without options.
  2. For NL94X-SH harmonic generator option. Harmonic outputs are not simultaneous; only single wavelength beam is present at the output at once.
  3. Standard deviation value averaged over 30 s after 20 minutes of warm-up.
  4. Deviation from average value measured over 8 hours of operation when room temperature variation is less than ±2 °C.
  5. Measured with photodiode with 100 ps rise time and oscilloscope with 600 MHz bandwidth.
  6. Standard deviation value, measured with respect to triggering pulse.
  7. Beam diameter is measured at 1064 nm at laser output at the 1/e² level and can vary with each unit we manufacture.
  8. Full angle measured at the 1/e² level at 1064 nm.
  9. Mains voltage should be specified when ordering.
