Illuminator for High Pulse Repetition Rate

Up to 10 kHz – 20 W average power

That illuminator can generate pulses from 100 to 200 ns with energies from 1 to 2.5 mJ depending on the pulse width. It can support high pulse repetition rates (up to 10 kHz) with a maximum average power of 20 W.
That module integrates a laser diode and a driver board into a closed protecting housing. Components of that module have been selected to provide the highest possible efficiency, leading to a low power consumption. Additional equipment required to operate that illuminator, such as external 12 VDC power supplies, function generator and thermoelectric assembly for active cooling, can be provided as an option.

  • Energy and pulse width from 1mJ/100ns to 2.5mJ/200ns
  • Up to 10 kHz pulse repetition rate
  • Up to 20 W average power
  • Single wavelength emission among 808, 915, 940 or 980 nm (other wavelengths in option)
  • Fast axis collimation of diode bars included
  • High reliability (> 100 x 109 shots)
  • Robust design integrated into a closed protective housing



That illuminator integrates a laser diode and a driver board whose combination allows generation of nanosecond pulses. Laser diode design and manufacturing benefit from the sound know-how of Quantel’s Diode Department in hard solder technology already developed for QCW laser diodes to ensure efficiency and reliability. With its proprietary technology for nanosecond pulsed laser diode illuminators, Quantel offers unique laser sources that are compact, low-cost and highly efficient. While high output average power (typically higher than 2 W) will require a suitable cooling system, low output average powers make these laser diode sources ideal for integration into portable and even hand held devices. Typical applications are photoacoustics, NIR spectroscopy, ultrasound generation, 3D flash LIDAR or time of flight measurements.
