Illuminateur à pulses courts version intégrée dans un boitier

Illuminateur impulsionnel à diode laser

coche-blanche

Illuminator for short pulses (30-100 ns)

From 30 ns - 1 mJ to 100 ns - 4 mJ

That illuminator can generate pulses from 30 to 100 ns with energies from 1 to 4 mJ depending on the pulse width. It can support pulse repetition rates in the range 1-6 kHz, depending on output energy per pulse, with a maximum average power of 6 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, and the brightest possible emission. Additional equipment required to operate that illuminator, such as external low voltage power supplies, function generator and thermoelectric assembly for active cooling, can be provided as an option.

  • Energy and pulse width from 1 mJ/30ns to 4mJ/100ns
  • Maximal pulse repetition rate between 1 and 6 kHz
  • Up to 6 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.
